系统可以利用声音信号产生带有回声的声音文件，并可以从带有回声的文件中消除回声而得到原声音信号；另外，系统还能从中估计反射物的距离(System can make use of the voice signals of the sound files with echoes and echoes from the document with echo and obtain the elimination of the original voice signal In addition, the system can also have to guess the distance from the reflective material)

说明：  用DCT算法做数字水印，水印为伪随即序列。对整个图做DCT变换(DCT algorithm used as a digital watermark, watermark for the pseudo-then sequence. The entire plan to do DCT)

利用BLACKMANHARRIS窗口设计一个频率采样型FIR滤波器，对一段含噪音的音乐信号进行滤波去噪处理并根据滤波前后的波形和频谱分析滤波性能。(design a frequency-sampling FIR filter utilizing BLACKMANHARRIS window to filter and de-noise some of the music signal,and analysis filtering performance based on waveform and spectral before and after filtering.)

图像处理的梯度算法，本身还行，有兴趣的可以研究一下(Gradient image processing algorithms, their okay, are interested can look at)

我用matlab写的一个corner detector, 效果比现在流行的harris，susan，CSS等效果要好。 Algorithm is derived from: X.C. He and N.H.C. Yung, Curvature Scale Space Corner Detector with Adaptive Threshold and Dynamic Region of Support , Proceedings of the 17th International Conference on Pattern Recognition, 2:791-794, August 2004. Improved algorithm has been included in A Corner Detector based on Global and Local Curvature Properties and submitted to Optical Engineering. (err)

斯坦福大学机器学习课程的一个源代码例子，对于机器学习和deep learning的学习研究很有帮助(this codes are from standford university,which are about machine learning and deep learning.they will be helpful in this research field)

小波图像二次压缩，MATLAB简单编程,改下路径即可用(Wavelet image compression)
