提取纹理特征，现在最流行的是gabor小波变换，它的集具有一定的方向性，和纹理特征吻合-Extraction of texture features, and now the most popular is the gabor wavelet transform, it sets a certain direction, and texture characteristics of anastomosis

MULTIGEN公司VEGA PRIME中对于物体碰撞检测的算法源码，对于碰撞检测的必看程序。-MultiGen Inc. VEGA PRIME for objects in the collision detection algorithm source code for the collision detection procedure of the must-see.

图形图像处理函数命令及详细列表，很详细地介绍了图形图像处理函数接口.-Graphic image processing function and a detailed list of commands, it is a detailed description of the graphic interface of image processing functions.

（1）应用9×9的窗口对上述图象进行随机抽样，共抽样200块子图象； （2）将所有子图象按列相接变成一个81维的行向量； （3）对所有200个行向量进行KL变换，求出其对应的协方差矩阵的特征向量和特征值，按降序排列特征值以及所对应的特征向量； （4）选择前40个最大特征值所对应的特征向量作为主元，将原图象块向这40个特征向量上投影，所获得的投影系数就是这个子块的特征向量。 （5）求出所有子块的特征向量。 -(1) the application of 9 × 9 window of these images at random, a total sample of 200 sub-image (2) all sub-images according to out-phase into a 81-dimensional row vector (3) all 200 lines for KL transform vector, derived its corresponding covariance matrix of eigenvectors and eigenvalues, in descending order by eigenvalue and the corresponding eigenvector (4) a choice to 40 corresponding to the largest eigenvalue eigenvector as the PCA, the original image block to the 40 feature vectors on the projection, the projection coefficients obtained by this sub-block eigenvector. (5) calculated for all sub-block eigenvector.

背景差分法（Frame difference）这种方法是基于前景和背景的不同场景，根据视频采集的背景信息获取更稳定的可信信息，计算前景中固定的背景像素差分，从而实现基于Su（pixel-based）和高端basic的融合区域（基于区域的）信息
