Generally used functions of face recognition interface: (Take Alibaba Cloud face recognition interface as an example)

Face detection and facial features positioning

Identify whether there is a face in the image you have authorized and give the face area. After face detection, return the coordinates of the detected face rectangular frame. It can support the simultaneous detection of up to thousands of faces, support plane 360-degree rotating face detection, and support left and right side face detection up to 90 degrees. At the same time, the key points of facial features in the image are extracted in milliseconds, and 105 key points of the face are identified and positioned.

Face comparison 1:1

Based on the two images that have been authorized to be input, the face in the two images can be detected, and the largest face in the two images can be selected for comparison to determine whether it is the same person. At the same time, the coordinates of the rectangular frame of the two faces, the confidence of the comparison, and the confidence thresholds of different misrecognition rates are returned.

Face Search 1:N

Based on the authorized input image or video, it is compared with the customer’s authorized registration database to achieve 1:N face recognition. It is suitable for face login, VIP face recognition and other scenarios that do not require card verification. Provide SDK calling method, support non-interactive or motion live body detection, support multiple platforms, CPU and GPU computing modes, and flexible deployment. Through massive data sample training and continuous training and tuning of CNN network models, an identity comparison network takes into account efficiency and accuracy.
