A developer needs to detect faces in photos and retrieve 27 facial landmark points, head-pose angles, and a limited age-estimate attribute. Which Azure service should they use?
Azure Face service
Azure Video Indexer service
Azure Computer Vision service
Azure Cognitive Search service
The Azure Face service is designed for detailed facial analysis. Its Detect API can return bounding boxes, 27-point landmarks, head-pose roll/yaw/pitch values, and (in approved scenarios) an age attribute. The Azure Computer Vision Image Analysis API only returns a basic face rectangle without these detailed attributes. Azure Cognitive Search indexes data, and Azure Video Indexer extracts insights from video, making them unsuitable for fine-grained face analysis in still images.
