The image analysis feature automatically generates tags, descriptions, and color data for image assets using Microsoft Azure AI services, which is an image recognition tool. The image analysis feature does not process video assets, as they have their own flow.
The Image analysis section is located on the asset details page, as shown in the following example. The asset type in this example is Social Media Asset, which is a defined taxonomy. Only the Tags and Colors properties can be edited.
You cannot train the AI and you cannot improve the results; however, you can change the confidence level in the vision media processing flows, which is by default set to 0.5.
