说明：  用来解决压缩感知里求解优化问题的算法matlab代码(solves the minimization problem. min_u ||u||_1+ lambda ||a*u- f||_2^2. algorithms are based on greedy coordinate descent and the bregman iterative method. matlab 7.5 (r2007b) image processing, mathematics, optimization, resconstruction . )

To find and estimate of the best solution and parameter in our problem we can use the evolutionary programming. PSO (particle swarm optimization) is an applicable method to catch this target. In these files I show the Simple PSO that it can be base of solve complicated problem, the code could run by MATLAB.

其中包括颜色矩特征提取，四层小波特征提取以及kmeans聚类算法，Matlab编程实现，希望对学习有帮助(Including the extraction of color moment feature, the four layer wavelet feature extraction and kmeans clustering algorithm, Matlab programming, and they hope to help with learning)
