Face Recognition Face Recognition

https://ai.aliyun.com/face

Face Recognition Based on face detection in the image or video analysis and matching techniques, to provide positioning face detection, face recognition and face attributes other than an independent service module. Can provide high-performance online service API for developers and businesses, applied to the face AR, face recognition and certification, large-scale search of the human face, photo management and other scenes.

Product features include:

Face detection and location

It was identified whether a face image and the face region are given, for face to face return detection coordinates detected rectangle. Can support up to thousands of simultaneous detection of human faces, a plane support face detection 360 degree rotation, supports a maximum of 90 degrees left and right side face detection. Meanwhile millisecond extracted face image features key, identifying key face 105 is positioned.

Face Recognition Properties

In the face detection based on the recognition of each person's face to detect gender (male / female), age, facial expression (smiling / laughing), glasses (wearing / not wearing) four attributes. Return to face the 1024 feature-dimensional depth study, based on the characteristics and features in accordance with the rules of comparison, users can achieve high performance of face recognition. Our algorithm in the open test set lfw reached 99.58% recognition accuracy.

Face alignment

Two pictures based on user input, can detect human faces in the two pictures, and pick two pictures of the largest face, and determines whether the same person. Returning the two men face rectangle coordinates, than the confidence level, confidence threshold and the error rate is different.
