基于数字图像跟matlab对车辆空位统计系统的实现，实现灰度图像的二值化，边缘检测等-Based on digital image with matlab of vehicle space statistical system, realize the gray image binarization, edge detection and so on

对彩色图像进行二值化，灰度图像非线性变换，指数变换，幂次变换从而得到直方图进行分析。(The binarization of the color image, the non-linear transformation of the gray image, the exponential transformation and the power conversion are carried out to obtain the histogram for analysis)
