边缘检测VS梯度图像edge detection based on the sobel 这个算法比较完整，不错算法比较完整-edge detection based on the sobel 这个算法比较完整，不错算法比较完整

这个程序是用matlab实现的车辆跟踪。用到的算法是协方差，包括梯度，rgb颜色，边缘，距离等多种元素。-This program is a vehicle tracking using matlab. The algorithm used is the covariance, including gradient, rgb color, the edge from the other elements.

根据能量密度梯度对细胞图像及边缘进行加强。-According to the energy density gradient on cell image and edge enhanced.
