原图象加上水印-dct1_embed

混沌粒子群算法。将混沌搜索方法，用在粒子群算法中，避免了粒子群的陷入极小值的缺点。(Chaotic particle swarm algorithm. The chaos search method, use on the particle swarm algorithm, avoid the particle swarm into the minimum faults.)

实现matlab中figure窗口的最大化、最小化、移动等功能。(Matlab maximize the figure window is minimized, mobile and other functions.)

包括内插，还有成形滤波器等等调制时所用的matlab文件(Including interpolation, as well as shaping filter modulation, etc. used by the matlab file)
