Problems solved by technology

However, these convolutional neural networks have too many layers, need to train more than 100 million parameters, the model is complex, and the processing speed is slow. The processing speed of most algorithms is lower than 10 frames per second, so it is difficult to be directly used in practical application scenarios. middle

Embodiment Construction

[0047] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0048] see figure 1 As shown, the embodiment of the present invention provides a real-time video face recognition method based on visual tracking technology:

[0049] (1) Key frame processing

[0050] Divide every n frames of the video stream into an image group, the first frame of each image group is a key frame, and the second to nth frames are non-key frames, and the face detection algorithm is used to detect the video for each image group key frame The position of all faces in the frame and the facial key point position of each human face are aligned with the facial key point position of each human face; the facial feature value corresponding to the facial key point position of each human face is extracted, and the human The face in the video frame with the highest similarity of face feature value is the face recognition result.

Abstract

The invention discloses a real-time video face recognition method based on a vision tracking technology, which relates to the technical field of computer vision tracking. A video is divided into imagegroups. In each image group, the first frame is used as a key frame, and the other frames are non-key frames. In each key frame, a face recognition result is obtained through face detection and alignment, face feature extraction and face matching. In each non-key frame, a face recognition result is obtained by tracking a face detected in the non-key frame. Space position matching is carried out on two adjacent video frames of two adjacent image groups. If the space positions are consistent, the face is taken as the face recognition result of the latter image group. If the space positions areinconsistent, a face of which the face feature value is more similar to the face feature value of a face to be recognized is taken as the face recognition result of the latter image group. The speed of face recognition is greatly improved. The face recognition result of the former image group can be corrected in time.

Description

technical field [0001] The invention relates to the technical field of computer vision tracking, in particular to a real-time video face recognition method and system based on visual tracking technology. Background technique [0002] With the rapid development of the Internet, information security is becoming more and more important in social life, and identity authentication technology has a very important application status in all aspects of society. Traditional identity verification methods mainly include marked objects (keys, ID cards, etc.), specific knowledge (passwords, passwords, etc.) and the combination of marked objects and specific knowledge (bank card + password, etc.). Avoid problems such as loss, forgery, forgetting or misappropriation, and have the disadvantages of being unsafe, inconvenient, and unreliable. With the continuous expansion of the influence of cyberspace on human beings, traditional identity verification methods are increasingly unable to meet ...
