基于dct变换，实现matlab图像压缩源码，很有意思(Based on DCT transform, matlab image compression source code, very interesting)

说明：  基于非线性PCA准则的两个盲信号分离算法， 利用矩阵广义逆递推得到一种盲信号分离算法，采用梯度下降算法和线性寻优而得到另一种自适应盲信号分离算法(sourceseparation based nonlinear pca princple)

船舶垂荡时的波浪力计算程序。给需要的朋友。(Ship wave force calculation procedure.If anyone need can download it. equations)

This toolbox has functions to perform nonlinear diffusion images. This kind of image filtering is particularly useful for reducing noise and to simplify images for further segmentation. Much of these functions are based on Perona and Malick s work, and also on J. Weickert s papers. The fast AOS diffusion is implemented. There is also 3D diffusion functions, color image diffusion and Coherence-Enhancing diffusion (This toolbox has functions to perform nonl inear diffusion images.
