This function links edge points together into lists of coordinate pairs. Where an edge junction is encountered the list is terminated and a separate list is generated for each of the branches.

用于计算图像纹理特征的灰度共现矩阵。可计算水平，竖直，45，135度方向的共现矩阵。(Used to calculate the image texture gray co-occurrence matrix. Calculate the horizontal, vertical, 45,135 degrees direction co-occurrence matrices.)

算法是原始对偶算法，该方法充分的剖析了优化问题的结构，是求解二次规划问题的一个较好的算法。求解比采用matlab 的Quardprog求解速度快许多！(Algorithm is the original dual algorithm, this method is fully analyzed the optimization of structure, is to solve the quadratic programming problem of a good algorithm. To solve the fast Quardprog than using matlab to solve many!)

用matlab实现的快速均值算法，可以实现对图像去除噪声。(Using matlab to achieve fast means algorithm, can achieve an image to remove noise.)

说明：  ：Mean—shift算法是一种非参数密度估计算法，可以实现快速的最优匹配，在目标的实时跟踪领域起着非常 重要的作用。为了有效的将Mean—shift算法应用到灰度图像中，采用了以方向直方图建立目标模型的策略，提出了在灰 度图像中以Mean—shift为核心的目标跟踪算法。实验结果表明，该算法具有不受光照条件影响的优点，在低对比度的情 况下仍能实现稳定、实时的跟踪目标。(: Mean-shift algorithm is a nonparametric density estimation algorithm, the optimal matching can be fast, real-time tracking fields in the target plays an important role. In order to effectively Mean-shift algorithm will be applied to the gray image, the histogram used to establish the direction of the strategy target model is proposed in the gray image to Mean-shift tracking algorithm as the core. Experimental results show that the algorithm has the advantage of not lighting conditions, in the case of low contrast can still achieve stability, real-time tracking of targets.)
