    Computer Vision

    Extract rich information from images to categorize and process visual data—and perform machine-assisted moderation of images to help curate your services.

    Analyze an image

    This feature returns information about visual content found in an image. Use tagging, domain-specific models, and descriptions in four languages to identify content and label it with confidence. Use Object Detection to get location of thousands of objects within an image. Apply the adult/racy settings to help you detect potential adult content. Identify image types and color schemes in pictures.
