改进的图像拼接算法，基于sift算法，实现图像的自动拼接，测试，完美运行(Improved image mosaic algorithm based the sift algorithm to achieve automatic image stitching, test, run perfectly)

线性非时变系统的卷积的demo，有助于对卷积的理解。欢迎大家分享之-As one would learn in a basic signal processing/controls/dynamical systems class, the multiplication by an LTI transfer function F(s) in the frequency domain is the same operation as convolution with f(t) in the time domaininformation hiding that is known as self-embedding. In essence, the process embeds a copy of the media into itself, of course it goes without saying that the copy has to be encrypted before the embedding takes place. The program is written purely in MATLAB with some scripts in PHP and HTML.
