通过摄像头图像的提取，在FPGA开发板上实现的，主要实现了图像轮廓的提取-Extraction of the image through the camera, in the FPGA implementation of the development board, the main achievement of the image contour extraction

Abstract—This paper proposes a new technique for face detection and lip feature extraction. A real-time field-programmable gate array (FPGA) implementation of the two proposed techniques is also presented. Face detection is based on a naive Bay
