Abstract

The present invention relates to a face detection and tracking method based on FPGA. Firstly, video is collected, and then skin color threshold detection is performed, and the collected video data is converted from YUV format into a binary image, and then spatial filtering is performed to determine skin color pixels, and then Time filtering, to obtain the average value of the pixels of the current frame, to further determine the skin color pixels, and then to filter other skin color interference, to perform face tracking, to obtain real-time face detection results, and finally to use VGA for real-time display. The invention overcomes the cost of existing human face detection and the real-time problem of detection and tracking, the algorithm is relatively simple, the accuracy, speed and real-time performance are high, and the system cost is low.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an FPGA-based face detection and tracking method. Background technique [0002] At present, the detection object of the face detection method is a static image, but cannot accurately detect and track the face in the video sequence. For some face detection, if the background image is complex, it is difficult to distinguish the face from other objects; some detection results are greatly affected under different lighting conditions; some face is blocked by three points More than one is difficult to detect. The existing face detection processing system is not parallel processing like FPGA, so the real-time performance of detection and tracking is limited. Contents of the invention [0003] In view of this, the purpose of the present invention is to propose a FPGA-based face detection and tracking method, which overcomes the cost of existing face detection and the real-ti...
