利用OPENCV函数库所进行的极坐标变换。利用Hough变换进行直线、圆检测。计算一副彩色图像的色度-饱和度直方图。用卡尔曼滤波器跟踪一个旋转点。-OPENCV library use conducted by polar transformation. The use of a straight-line Hough transform, circle detection. Calculating a color image of the color- saturation histogram

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
