在图像识别领域中，图像提取是最基础也是最重要的一个环节．如果前期图像提取错误，无论识别技术多么高超，也不会识别出正确的对象．本程序演示如何从图象中提取人物轮廓-In the field of image recognition, image extraction is the most basic and most important aspect. If the pre-image extraction error, no matter how superb recognition techn

用于物体目标轮廓的提取与跟踪，能更好的识别出物体轮廓。-Target contour for object extraction and tracking, to better identify the contours of objects.

基于opencv的车牌识别源码，使用了canny算法进行边缘检测，然后二值化，接着用cvFindContours搜索轮廓，最后从找到的轮廓中根据角点的个数，角的度数和轮廓大小确定，矩形位置。-Opencv-based license plate recognition source code, using the canny edge detection algorithm, and then two values, followed by cvFindContours search profi
