blind source separation in matlab

A matlab gui for basic image processing operations

这是基于数字信号处理的滤波器设计，有FIR的和IIR的有6种不同的窗函数(IIR and FIR )

曲面光照matlab演示例程，通俗易懂，简单易学(Surface light matlab demo routines, user-friendly)

说明：  MAT LAB HACKING TOOLS

matched field processing定位仿真。根据porter的kraken模型跑出来的。(matched field processing positioning simulation. According porter ran out of the kraken model.)

说明：  林家浩教授和张亚辉教授的专著《随机振动的虚拟激励法》(Professor Lin Jiahao and Professor Zhang Yahui the monograph random vibration of the pseudo-excitation method)

四路抢答题，输入可以为四路不同信号，通过锁存抢答信号进行抢答。(Four-way scramble answer, for four different input signals, signals through the latch Answer Answer.)

说明：  add noise to a signal

该算法把计算出的图像不变质心作为对其进行对数极坐标变换的原 点, 再作傅立叶变换, 取出中频段幅值作为水印嵌入域。该算法具有较好的鲁棒性、可检测性, 能同时抵抗几何攻击和信号 处理攻击, 它在数字图像的版权保护等领域有广泛的应用前景。(The algorithm to calculate the heart of the image does not degenerate as the number of its polar transformation of the origin, further Fourier transform, remove the watermark embedding in the frequency domain as amplitude. The algorithm has better robustness, detectability, can also resist geometric attacks and signal processing attacks, which in the digital image copyright protection and other fields have a wide range of applications.)
