Quickstart: Image Analysis 4.0
Get started with the Image Analysis 4.0 REST API or client SDK to set up a basic image analysis application. The Image Analysis service provides you with AI algorithms for processing images and returning information on their visual features. Follow these steps to install a package to your application and try out the sample code.
Use the Image Analysis client SDK for .NET to analyze an image to read text and generate an image caption. This quickstart analyzes a remote image and prints the results to the console.

Tip
The Analysis 4.0 API can do many different operations. See the Analyze Image how-to guide for examples that showcase all of the available features.
Prerequisites
- An Azure subscription - Create one for free
- The Visual Studio IDE with workload .NET desktop development enabled. Or, if you don't plan on using Visual Studio IDE, you need the .NET SDK installed.
- Once you have your Azure subscription, create a Computer Vision resource in the Azure portal. In order to use the captioning feature in this quickstart, you must create your resource in one of the supported Azure regions (see Image captions). After it deploys, select Go to resource.
- You need the key and endpoint from the resource you create to connect your application to the Azure AI Vision service.
- You can use the free pricing tier (
F0
) to try the service, and upgrade later to a paid tier for production.
Set up application
Create a new C# application.
Open Visual Studio, and under Get started select Create a new project. Set the template filters to C#/All Platforms/Console. Select Console App (command-line application that can run on .NET on Windows, Linux and macOS) and choose Next. Update the project name to ImageAnalysisQuickstart and choose Next. Select .NET 6.0 or above, and choose Create to create the project.
Install the client SDK
Once you've created a new project, install the client SDK by right-clicking on the project solution in the Solution Explorer and selecting Manage NuGet Packages. In the package manager that opens select Browse, check Include prerelease, and search for Azure.AI.Vision.ImageAnalysis
. Select Install.
Create environment variables
In this example, write your credentials to environment variables on the local machine that runs the application.
Go to the Azure portal. If the resource you created in the Prerequisites section deployed successfully, select Go to resource under Next Steps. You can find your key and endpoint under Resource Management in the Keys and Endpoint page. Your resource key isn't the same as your Azure subscription ID.
To set the environment variable for your key and endpoint, open a console window and follow the instructions for your operating system and development environment.
- To set the
VISION_KEY
environment variable, replace<your_key>
with one of the keys for your resource. - To set the
VISION_ENDPOINT
environment variable, replace<your_endpoint>
with the endpoint for your resource.
Important
If you use an API key, store it securely somewhere else, such as in Azure Key Vault. Don't include the API key directly in your code, and never post it publicly.
For more information about AI services security, see Authenticate requests to Azure AI services.
setx VISION_KEY <your_key>
setx VISION_ENDPOINT <your_endpoint>
After you add the environment variables, you may need to restart any running programs that will read the environment variables, including the console window.
Analyze Image
From the project directory, open the Program.cs file that was created previously with your new project. Paste in the following code:
Tip
The code shows analyzing an image URL. You can also analyze a local image file, or an image from a memory buffer. For more information, see the Analyze Image how-to guide.
using Azure;
using Azure.AI.Vision.ImageAnalysis;
using System;
public class Program
{
static void AnalyzeImage()
{
string endpoint = Environment.GetEnvironmentVariable("VISION_ENDPOINT");
string key = Environment.GetEnvironmentVariable("VISION_KEY");
ImageAnalysisClient client = new ImageAnalysisClient(
new Uri(endpoint),
new AzureKeyCredential(key));
ImageAnalysisResult result = client.Analyze(
new Uri("https://learn.microsoft.com/azure/ai-services/computer-vision/media/quickstarts/presentation.png"),
VisualFeatures.Caption | VisualFeatures.Read,
new ImageAnalysisOptions { GenderNeutralCaption = true });
Console.WriteLine("Image analysis results:");
Console.WriteLine(" Caption:");
Console.WriteLine($" '{result.Caption.Text}', Confidence {result.Caption.Confidence:F4}");
Console.WriteLine(" Read:");
foreach (DetectedTextBlock block in result.Read.Blocks)
foreach (DetectedTextLine line in block.Lines)
{
Console.WriteLine($" Line: '{line.Text}', Bounding Polygon: [{string.Join(" ", line.BoundingPolygon)}]");
foreach (DetectedTextWord word in line.Words)
{
Console.WriteLine($" Word: '{word.Text}', Confidence {word.Confidence.ToString("#.####")}, Bounding Polygon: [{string.Join(" ", word.BoundingPolygon)}]");
}
}
}
static void Main()
{
try
{
AnalyzeImage();
}
catch (Exception e)
{
Console.WriteLine(e);
}
}
}
Build and run the application by selecting Start Debugging from the Debug menu at the top of the IDE window (or press F5).
Output
The console output should show something similar to the following text:

Clean up resources
If you want to clean up and remove an Azure AI services subscription, you can delete the resource or resource group. Deleting the resource group also deletes any other resources associated with it.
Next steps
In this quickstart, you learned how to install the Image Analysis client SDK and make basic image analysis calls. Next, learn more about the Analysis 4.0 API features.
- Image Analysis overview
- Sample source code can be found on GitHub.
Use the Image Analysis client SDK for Python to analyze an image to read text and generate an image caption. This quickstart analyzes a remote image and prints the results to the console.

Prerequisites
- An Azure subscription - Create one for free
- Python 3.x. Your Python installation should include pip. You can check if you have pip installed by running
pip --version
on the command line. Get pip by installing the latest version of Python. - Once you have your Azure subscription, create a Computer Vision resource in the Azure portal. In order to use the captioning feature in this quickstart, you must create your resource in one of the supported Azure regions (see Image captions for the list of regions). After it deploys, select Go to resource.
- You need the key and endpoint from the resource you create to connect your application to the Azure AI Vision service.
- You can use the free pricing tier (

setx VISION_KEY <your_key>
setx VISION_ENDPOINT <your_endpoint>
After you add the environment variables, you may need to restart any running programs that will read the environment variables, including the console window.
Analyze image
Open a command prompt where you want the new project, and create a new file named quickstart.py.
Run this command to install the Image Analysis SDK:
pip install azure-ai-vision-imageanalysis
Copy the following code into quickstart.py:
Tip
The code shows analyzing an image URL. You can also analyze an image from the program memory buffer. For more information, see the Analyze Image how-to guide.
import os from azure.ai.vision.imageanalysis import ImageAnalysisClient from azure.ai.vision.imageanalysis.models import VisualFeatures from azure.core.credentials import AzureKeyCredential # Set the values of your computer vision endpoint and computer vision key # as environment variables: try: endpoint = os.environ["VISION_ENDPOINT"] key = os.environ["VISION_KEY"] except KeyError: print("Missing environment variable 'VISION_ENDPOINT' or 'VISION_KEY'") print("Set them before running this sample.") exit() # Create an Image Analysis client client = ImageAnalysisClient( endpoint=endpoint, credential=AzureKeyCredential(key) ) # Get a caption for the image. This will be a synchronously (blocking) call. result = client.analyze_from_url( image_url="https://learn.microsoft.com/azure/ai-services/computer-vision/media/quickstarts/presentation.png", visual_features=[VisualFeatures.CAPTION, VisualFeatures.READ], gender_neutral_caption=True, # Optional (default is False) ) print("Image analysis results:") # Print caption results to the console print(" Caption:") if result.caption is not None: print(f" '{result.caption.text}', Confidence {result.caption.confidence:.4f}") # Print text (OCR) analysis results to the console print(" Read:") if result.read is not None: for line in result.read.blocks[0].lines: print(f" Line: '{line.text}', Bounding box {line.bounding_polygon}") for word in line.words: print(f" Word: '{word.text}', Bounding polygon {word.bounding_polygon}, Confidence {word.confidence:.4f}")
Then run the application with the
python
command on your quickstart file.python quickstart.py
Output
The console output should show something similar to the following text:

Clean up resources
If you want to clean up and remove an Azure AI services subscription, you can delete the resource or resource group. Deleting the resource group also deletes any other resources associated with it.
Next steps
In this quickstart, you learned how to install the Image Analysis client SDK and make basic image analysis calls. Next, learn more about the Analysis 4.0 API features.
- Image Analysis overview
- Sample source code can be found on GitHub.
Use the Image Analysis client SDK for Java to analyze an image to read text and generate an image caption. This quickstart analyzes a remote image and prints the results to the console.
Reference documentation | Maven Package | Samples
Tip
The Analysis 4.0 API can do many different operations. See the Analyze Image how-to guide for examples that showcase all of the available features.
Prerequisites
- A Windows 10 (or higher) x64, or Linux x64 machine.
- Java Development Kit (JDK) version 8 or above installed, such as Azul Zulu OpenJDK, Microsoft Build of OpenJDK, Oracle Java, or your preferred JDK. Run
java -version
from a command line to see your version and confirm a successful installation. Make sure that the Java installation is native to the system architecture and not running through emulation. - Apache Maven installed. On Linux, install from the distribution repositories if available. Run
mvn -v
to confirm successful installation. - An Azure subscription - Create one for free
- Once you have your Azure subscription, create a Computer Vision resource in the Azure portal. In order to use the captioning feature in this quickstart, you must create your resource in one of the supported Azure regions (see Image captions). After it deploys, select Go to resource.
- You need the key and endpoint from the resource you create to connect your application to the Azure AI Vision service.
- You can use the free pricing tier (
F0
) to try the service, and upgrade later to a paid tier for production.
Set up application
Open a console window and create a new folder for your quickstart application.
Open a text editor and copy the following content to a new file. Save the file as
pom.xml
in your project directory<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.example</groupId> <artifactId>my-application-name</artifactId> <version>1.0.0</version> <dependencies> <!-- https://mvnrepository.com/artifact/com.azure/azure-ai-vision-imageanalysis --> <dependency> <groupId>com.azure</groupId> <artifactId>azure-ai-vision-imageanalysis</artifactId> <version>1.0.0-beta.2</version> </dependency> <!-- https://mvnrepository.com/artifact/org.slf4j/slf4j-nop --> <!-- Optional: provide a slf4j implementation. Here we use a no-op implementation just to make the slf4j console spew warning go away. We can still use the internal logger in azure.core library. See https://github.com/Azure/azure-sdk-for-java/tree/main/sdk/vision/azure-ai-vision-imageanalysis#enable-http-requestresponse-logging --> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-nop</artifactId> <version>1.7.36</version> </dependency> </dependencies> </project>
Update the version value (
1.0.0-beta.2
) based on the latest available version of the azure-ai-vision-imageanalysis package in the Maven repository.Install the SDK and dependencies by running the following in the project directory:
mvn clean dependency:copy-dependencies
Once the operation succeeds, verify that the folders
target\dependency
were creating and they contain.jar
files.
Create environment variables
In this example, write your credentials to environment variables on the local machine that runs the application.
Go to the Azure portal. If the resource you created in the Prerequisites section deployed successfully, select Go to resource under Next Steps. You can find your key and endpoint under Resource Management in the Keys and Endpoint page. Your resource key isn't the same as your Azure subscription ID.
To set the environment variable for your key and endpoint, open a console window and follow the instructions for your operating system and development environment.
- To set the
VISION_KEY
environment variable, replace<your_key>
with one of the keys for your resource. - To set the
VISION_ENDPOINT
environment variable, replace<your_endpoint>
with the endpoint for your resource.
Important
If you use an API key, store it securely somewhere else, such as in Azure Key Vault. Don't include the API key directly in your code, and never post it publicly.
For more information about AI services security, see Authenticate requests to Azure AI services.
setx VISION_KEY <your_key>
setx VISION_ENDPOINT <your_endpoint>
After you add the environment variables, you may need to restart any running programs that will read the environment variables, including the console window.
Analyze Image
Open a text editor and copy the following content to a new file. Save the file as ImageAnalysis.java
import com.azure.ai.vision.imageanalysis.*;
import com.azure.ai.vision.imageanalysis.models.*;
import com.azure.core.credential.KeyCredential;
import java.util.Arrays;
public class ImageAnalysisQuickStart {
public static void main(String[] args) {
String endpoint = System.getenv("VISION_ENDPOINT");
String key = System.getenv("VISION_KEY");
if (endpoint == null || key == null) {
System.out.println("Missing environment variable 'VISION_ENDPOINT' or 'VISION_KEY'.");
System.out.println("Set them before running this sample.");
System.exit(1);
}
// Create a synchronous Image Analysis client.
ImageAnalysisClient client = new ImageAnalysisClientBuilder()
.endpoint(endpoint)
.credential(new KeyCredential(key))
.buildClient();
// This is a synchronous (blocking) call.
ImageAnalysisResult result = client.analyzeFromUrl(
"https://learn.microsoft.com/azure/ai-services/computer-vision/media/quickstarts/presentation.png",
Arrays.asList(VisualFeatures.CAPTION, VisualFeatures.READ),
new ImageAnalysisOptions().setGenderNeutralCaption(true));
// Print analysis results to the console
System.out.println("Image analysis results:");
System.out.println(" Caption:");
System.out.println(" \"" + result.getCaption().getText() + "\", Confidence "
+ String.format("%.4f", result.getCaption().getConfidence()));
System.out.println(" Read:");
for (DetectedTextLine line : result.getRead().getBlocks().get(0).getLines()) {
System.out.println(" Line: '" + line.getText()
+ "', Bounding polygon " + line.getBoundingPolygon());
for (DetectedTextWord word : line.getWords()) {
System.out.println(" Word: '" + word.getText()
+ "', Bounding polygon " + word.getBoundingPolygon()
+ ", Confidence " + String.format("%.4f", word.getConfidence()));
}
}
}
}
Tip
The code analyzes an image from a URL. You can also analyze an image from the program memory buffer. For more information, see the Analyze Image how-to guide.
To compile the Java file, run the following command:
javac ImageAnalysis.java -cp ".;target/dependency/*"
You should see the file ImageAnalysis.class
created in the current folder.
To run the application, run the following command:
java -cp ".;target/dependency/*" ImageAnalysis
Output
The console output should show something similar to the following text:
Image analysis results:

Use the Image Analysis client SDK for JavaScript to analyze an image to read text and generate an image caption. This quickstart analyzes a remote image and prints the results to the console.
Reference documentation | Package (npm) | Samples
Tip
The Analysis 4.0 API can do many different operations. See the Analyze Image how-to guide for examples that showcase all of the available features.
Prerequisites
- An Azure subscription - Create one for free
- The current version of Node.js
- The current version of Edge, Chrome, Firefox, or Safari internet browser.
- Once you have your Azure subscription, create a Computer Vision resource in the Azure portal to get your key and endpoint. In order to use the captioning feature in this quickstart, you must create your resource in one of the supported Azure regions (see Image captions for the list of regions). After it deploys, select Go to resource.
- You need the key and endpoint from the resource you create to connect your application to the Azure AI Vision service.
- You can use the free pricing tier (
F0
) to try the service, and upgrade later to a paid tier for production.
Create environment variables
In this example, write your credentials to environment variables on the local machine that runs the application.
Go to the Azure portal. If the resource you created in the Prerequisites section deployed successfully, select Go to resource under Next Steps. You can find your key and endpoint under Resource Management in the Keys and Endpoint page. Your resource key isn't the same as your Azure subscription ID.
To set the environment variable for your key and endpoint, open a console window and follow the instructions for your operating system and development environment.
- To set the
VISION_KEY
environment variable, replace<your_key>
with one of the keys for your resource. - To set the
VISION_ENDPOINT
environment variable, replace<your_endpoint>
with the endpoint for your resource.
Important
If you use an API key, store it securely somewhere else, such as in Azure Key Vault. Don't include the API key directly in your code, and never post it publicly.
For more information about AI services security, see Authenticate requests to Azure AI services.
setx VISION_KEY <your_key>
setx VISION_ENDPOINT <your_endpoint>
After you add the environment variables, you may need to restart any running programs that will read the environment variables, including the console window.
Analyze image
Create a new Node.js application
In a console window (such as cmd, PowerShell, or Bash), create a new directory for your app, and navigate to it.
mkdir myapp && cd myapp
Run the
npm init
command to create a node application with apackage.json
file.npm init
Install the client library
Install
@azure-rest/ai-vision-image-analysis
npm package:npm install @azure-rest/ai-vision-image-analysis
Also install the dotenv package:
npm install dotenv
Your app's
package.json
file will be updated with the dependencies.Create a new file, index.js. Open it in a text editor and paste in the following code.
const { ImageAnalysisClient } = require('@azure-rest/ai-vision-image-analysis'); const createClient = require('@azure-rest/ai-vision-image-analysis').default; const { AzureKeyCredential } = require('@azure/core-auth'); // Load the .env file if it exists require("dotenv").config(); const endpoint = process.env['VISION_ENDPOINT']; const key = process.env['VISION_KEY']; const credential = new AzureKeyCredential(key); const client = createClient(endpoint, credential); const features = [ 'Caption', 'Read' ]; const imageUrl = 'https://learn.microsoft.com/azure/ai-services/computer-vision/media/quickstarts/presentation.png'; async function analyzeImageFromUrl() { const result = await client.path('/imageanalysis:analyze').post({ body: { url: imageUrl }, queryParameters: { features: features }, contentType: 'application/json' }); const iaResult = result.body; if (iaResult.captionResult) { console.log(`Caption: ${iaResult.captionResult.text} (confidence: ${iaResult.captionResult.confidence})`); } if (iaResult.readResult) { iaResult.readResult.blocks.forEach(block => console.log(`Text Block: ${JSON.stringify(block)}`)); } } analyzeImageFromUrl();
Run the application with the
node
command on your quickstart file.node index.js
Clean up resources
If you want to clean up and remove an Azure AI services subscription, you can delete the resource or resource group. Deleting the resource group also deletes any other resources associated with it.
Next steps
In this quickstart, you learned how to install the Image Analysis client library and make basic image analysis calls. Next, learn more about the Analyze API features.
- Image Analysis overview
- The source code for this sample can be found on GitHub.
Use the Image Analysis REST API to read text and generate captions for the image (version 4.0 only).
Tip
The Analysis 4.0 API can do many different operations. See the Analyze Image how-to guide for examples that showcase all of the available features.
Prerequisites
- An Azure subscription - Create one for free
- Once you have your Azure subscription, create a Computer Vision resource in the Azure portal to get your key and endpoint. In order to use the captioning feature in this quickstart, you must create your resource in certain Azure regions. See Region availability. After it deploys, select Go to resource.
- You'll need the key and endpoint from the resource you create to connect your application to the Azure AI Vision service. You'll paste your key and endpoint into the code below later in the quickstart.
- You can use the free pricing tier (
F0
) to try the service, and upgrade later to a paid tier for production.
- cURL installed
Analyze an image
To analyze an image for various visual features, do the following steps:
Copy the following
curl
command into a text editor.curl.exe -H "Ocp-Apim-Subscription-Key: <subscriptionKey>" -H "Content-Type: application/json" "<endpoint>/computervision/imageanalysis:analyze?features=caption,read&model-version=latest&language=en&api-version=2024-02-01" -d "{'url':'https://learn.microsoft.com/azure/ai-services/computer-vision/media/quickstarts/presentation.png'}"
Make the following changes in the command where needed:
- Replace the value of
<subscriptionKey>
with your Vision resource key. - Replace the value of
<endpoint>
with your Vision resource endpoint URL. For example:https://YourResourceName.cognitiveservices.azure.com
. - Optionally, change the image URL in the request body (
https://learn.microsoft.com/azure/ai-services/computer-vision/media/quickstarts/presentation.png
) to the URL of a different image to be analyzed.
- Replace the value of
Open a command prompt window.
Paste your edited
curl
command from the text editor into the command prompt window, and then run the command.
