Problems solved by technology

[0003] At present, there is no mature face detection and tracking method or system that can be applied to complex monitoring environments. The real-time detection and continuous tracking method and system" Chinese patent application, which can only solve the real-time detection and tracking of frontal upright faces, and in actual application conditions, the frontal upright faces can only reach about 25%

Embodiment Construction

[0053] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0054] Such as figure 1 and figure 2 As shown, the present invention provides a kind of multi-pose human face detection and tracking method, comprising:

[0055] Step S1, decoding the image captured by the camera and restoring it into a frame picture, and performing preprocessing of light compensation on the frame picture;

[0056] Preferably, in the step S1, since the face will reflect various light from the outside world, the face image collected by the camera will not only include the specific information of the face, but also include other external information, such as illumination changes, etc., so Before acquiring the face picture, the present invention preprocesses the collected image, which is a very important link in the...

Abstract

The present invention relates to a method and a system for detecting and tracking a multi-pose face. The method includes the following steps of :1) decoding an image acquired by a camera, and restoring the decoded image into a frame picture, and performing pre-process of illumination compensation on the frame picture; 2) acquiring a facial picture from the pre-processed frame picture; 3) determining whether a face in the facial picture is a false face or not, if not, predicting a moving track of the face, and tracking the face and judging whether the track is missing or not according to a predicted result, if not, positioning and acquiring a location of a next facial picture in a next frame picture according to the predicted result, and repeating the operations from step 1) to step 3), if yes, selecting five facial pictures with optimal rotation angles and definitions; and discarding the facial picture if the face is a false face. The method and the system provided in the invention can overcome influences of instability of facial poses and changes in ambient light, distinguish the facial poses in a real-time manner and screen out facial pictures with optimal poses.

Description

technical field [0001] The invention relates to a multi-pose human face detection and tracking method and system. Background technique [0002] The multi-pose face detection and tracking problem is a research topic developed in recent years. At present, the face detection algorithm of static pictures is gradually becoming mature. However, due to the dynamic scenes or faces in real-time videos may encounter various Such external environmental disturbances, such as illumination changes, face poses, partial occlusions, etc., limit the application of face detection systems in actual monitoring. [0003] At present, there is no mature face detection and tracking method or system that can be applied to complex monitoring environments. "Method and system for real-time detection and continuous tracking" of the Chinese patent application, which can only solve the real-time detection and tracking of frontal upright faces, and the frontal upright faces can only reach about 25% in actu...
