Microsoft Azure Cognitive Services: Inside-Out
As mentioned above, this product’s capabilities reach human parity. So, what exactly does Azure Cognitive Services have under the hood? Let’s explore in more detail.
Microsoft’s Vision APIs analyze visual content (images, video and digital ink) and identify objects within it. The APIs therefore enable apps to authenticate and group faces according to specific characteristics, or to detect specified objects and details.
Vision APIs include:
- Computer Vision. The service helps analyze and enhance the discoverability of visual content: it extracts and recognizes text, tags and categorizes images, generates descriptions, and recognizes human faces and other objects.
- Custom Vision. The service customizes computer vision models to specific business requirements.
- This API helps detect human faces in an image with attribute features such as age, gender, pose, smile and facial hair, and emotions.
- Form Recognizer. This API helps detect and extract required forms of content.
- Video Indexer. This API tracks and identifies visual content in videos, extracts audio transcriptions, detects scenes, interprets text, analyzes sentiment, searches images and events in a video, and then indexes this information.
