利用opencv对图像进行哈夫变换，Hough变换利用图像空间和Hough参数空间的点－线对偶性，把图像空间中的检测问题转换到参数空间。通过在参数空间里进行简单的累加统计，然后在Hough参数空间寻找累加器峰值的方法检测直线。-Opencv use the Hough transform to the image, Hough transformation point- line Duality image space and Hough parameter space to the image

霍夫变化直线检测程序，用于检测图像中的直线，本算法涉及梯度变化，感觉检测效果还不错。望指正。-Hough variation straight line detection procedures, is used to detect the image of straight line, the present algorithm involves gradient change, the feeling detection effect Huan pretty good. Look corre

实现图像边缘检测，采用的是canny算法，需要改变程序中的图像路径，因人而异~-Realization of image edge detection, using a canny algorithm, the program needs to change the image path, vary ~
