Problems solved by technology

However, face detection is still a task with a huge amount of computation, especially on embedded devices that do not have floating-point computing functions, most of them can only rely on adding one or more digital signal processors (DSP) with relatively strong computing capabilities. To specialize in the calculation of face detection algorithms, obviously, such hardware cost investment is very high

Abstract

The invention relates to a face detection and tracking method based on statistic data, wherein the existing statistic data of a digital signal processor in a system is taken as the basis, a mass of non-face region is eliminated, then face detection is realized on CPU, a fast face detection algorithm which supports a vector machine and is based on local binary mode characteristic is run, and finally face tracking is carried out according to motion vector data. The face detection and tracking method based on statistic data is clear and is high in detection precision and fast in speed.

Description

technical field [0001] The invention relates to the field of embedded intelligent video analysis and monitoring, in particular to a face detection and tracking method based on statistical data of a digital signal processor (DSP). Background technique [0002] Face detection (Face Detection) is to detect the existence of faces from various scenes and determine their positions. Face tracking is to track the detected faces on the basis of face detection. Face detection and tracking technology can be applied to a new generation of human-machine interface, security access and video surveillance, and content-based retrieval and other fields. Today, with the rapid development of video cameras, cameras and security monitoring equipment, face detection and tracking are getting more and more attention, and gradually become a standard configuration. Currently, mainstream digital cameras and video cameras have this function. , it can provide entertainment and focus assist functions in ...
