针对图像处理中边缘检测器普遍存在的漏检问题，提出了一种漏检的自动补偿方法，该法可准确而快速地实现指定方向上单边缘跟踪与漏检补偿．实验结果表明，将该法用于人脸轮廓线的跟踪与补偿，准确、速度快、效果好 In view of the ubiquitous detection problem of edge detector in image processing, a method of automatic detection of missing detection is proposed, which can accurately and quickly compensate single-edge tracking and missing detection in specified direction. The experimental results show that this method can be used to track and compensate the contour lines of human face, which is accurate, fast and effective
