Abstract

The invention discloses a face detection tracking method and device. The method comprises: acquiring a to-be-detected image and a target face image; detecting and describing feature points in the to-be-detected image and the target face image; matching feature points in the to-be-detected image and the target face image according to detection and description results; and performing face detectionand tracking according to a matching result. According to the method, the problem of accumulation during feature point extraction and the problem of noise during feature point description in an existing face detection tracking method are solved, and the face detection tracking accuracy is improved.

Description

Technical field [0001] The invention relates to the field of face recognition, in particular to a face detection and tracking method and device. Background technique [0002] Face detection technology means that for any given image, a certain strategy is used to search it to determine whether there is a face in it. If there is a face, it returns information such as the position and size of the face. The current face detection technology can be used in fields such as identity authentication and security protection, media and entertainment, and image search. Target tracking technology is generally based on processing a series of images, identifying targets from a complex background, and predicting the motion law of the targets to achieve continuous and accurate tracking of targets. This technology is used in modern military and civilian security. It occupies a very important position, and most of the targets are human faces. [0003] The process of face detection and tracking techn...
