OCR Demo on Vision Studio performs better than API call

Question

I've been testing out Optical Character Recognition using Azure. However, I've noticed that the online demo version performs far better than the API version. In addition, the API model version is stuck on 2023-10-01 instead of the 2024 version shown in the documentation. Can someone explain the discrepancy?

Answer 1

@Danny Zhang Thanks for getting back nd clarifying your ask. This api-version is supported 2024-02-01. However the SDK is not yet updated to use this new version and it is still using older version 2023-10-01.

.

So, if you want to use this 2024-02-01 api-version, try directly invoking it from the REST API as shown below:

POST https://XXXX.cognitiveservices.azure.com/computervision/imageanalysis:analyze?features=caption%2Cread&api-version=2024-02-01&gender-neutral-caption=true 
Content-Type: application/json 
Ocp-Apim-Subscription-Key: 337e4XXXXXXX4633cd7f 
Request Body:

{"url":"https://learn.microsoft.com/azure/ai-services/computer-vision/media/quickstarts/presentation.png"}

.

.

So, if you want to use this 2024-02-01 api-version, try directly invoking it from the Python code via REST API as shown below:

import requests

# Define the endpoint and parameters

url = "https://XXXX.cognitiveservices.azure.com/computervision/imageanalysis:analyze"

params = {

    'features': 'caption,read',

    'api-version': '2024-02-01',

    'gender-neutral-caption': 'true'

}

# Define the headers

headers = {

    'Content-Type': 'application/json',

    'Ocp-Apim-Subscription-Key': '337e4XXXXXXX4633cd7f'

}

# Define the request body

data = {

    'url': 'https://learn.microsoft.com/azure/ai-services/computer-vision/media/quickstarts/presentation.png'

}

# Make the POST request

response = requests.post(url, headers=headers, params=params, json=data)

# Print the response

print(response.status_code)

print(response.json())
