阵列信号处理的几个程序，是自己找的，可以看看(array signal processing)

Function to calculate the principal curvatures on a triangular mesh. Approximations of curvature are based on local (N=1) neighborhood elements and vertices. Note: Directions of curvatures aren t calculated appropriately. Will post an updated version once this is implemented. Note that calculations at vertices with few adjacent triangles, and hence few adjacent vertices, are expanded to a greater neighborhood.

利用LSB算法嵌入隐藏图像，可在广义LSB中设置修改的位平面，返回误码率和峰值信噪比。含各种经典的攻击方式，可用于实验。并可控制攻击的强弱。利用Matlab编写。(LSB embedding algorithm using hidden images, can be generalized to set up modified LSB bit-plane and returned to the bit error rate and peak signal to noise ratio. Containing a variety of classic attack methods can be used for the experiment. Can control the strength of the attack. Prepared using Matlab.)
