The Image Analyser Extension for Dynamics NAV

Article
12/01/2017

The Image Analyser extension uses powerful image analytics provided by the Computer Vision API for Microsoft Cognitive Services to detect attributes in the images that you import for items and contact persons, so you can easily review and assign them. For items, attributes could be whether the item is a table or a car, and whether it is red or blue. For contact persons, attributes can be gender or age.

Image Analyser suggests attributes based on tags that the Computer Vision API finds, and a confidence level. By default, it suggests attributes only if it is at least 80% sure that the attribute is correct. You can set another confidence level, if needed. To learn more about how the tags and confidence level are determined, see Computer Vision API.

Image Analyzer is free in Dynamics NAV, but there is a limit to the number of items that you can analyze during a certain period of time. By default, you can analyse 100 images per month.

After you enable the extension, Image Analyser runs each time you import an image to an item or contact person. You will see the attributes, confidence level, and details right away, and can decide what to do with each attribute. If you imported images before you enabled the Image Analyzer extension, you must go to the item or contact cards and choose the Analyze Picture action.

[!NOTE]
By enabling this extension you agree that Microsoft may store your data and use it to improve Microsoft services, such as making the Computer Vision API better. To help protect your privacy, we take steps to make your data anonymous and keep it secure. We will not publish your data or let other people use it. You can remove the image from the item in Dynamics NAV, however, the Computer Vision API will still have the image in its de-identified form. For more information, see Microsoft Trust Center.

Requirements

There are a few requirements for the images:

Image formats: JPEG, PNG, GIF, BMP
Maximum file size: Less than 4 MB
Image dimensions: Greater than 50 x 50 pixels

Blacklisting suggested attributes

If the analysis suggests an attribute that you do not want to see you can blacklist the attribute. Use caution, however. Blacklisted attributes are not suggested for other items or contact persons either. If you regret blacklisting an attribute, you can choose Blacklisted Attributes, and then delete the attribute from the list.

The Image Analyzer extension is built-in to Dynamics NAV. You just need to turn it on.
