用于图像精确匹配以及目标检测的SIFT算法(Sift algorithm matlab version for object detection and image match)

本matlab函数实现微分编码，可以处理通信信道中的偶发“倒相”现象，避免误码。(Matlab function of the differential encoding, communication channels can handle the occasional " down phase" phenomenon, to avoid error.)

This code is about Gabor convolution.

利用matlab演奏的生日快乐歌，别有一番风味，不妨一听(Using matlab played Happy Birthday, do not have a flavor, might one)

using gall function for measure the algorithm

使用小波变换提取信号的特征值，实现故障信号的视频分析，利用matlab进行仿真，证明判据的真实可信(wavelet based fault line detection)

bch编码技术的信道仿真,而且附加了解释(bch coding technology channel simulation, and an additional explanation)

hough transform to detect line

说明：  变模态分解（EMD）的代码，适用于对非平稳非线性信号的分解，分解后得到多个IMF和一个残基。(The code of variable modal decomposition (EMD) is suitable for the decomposition of non-stationary and nonlinear signals, and after decomposition, multiple IMFs and one residue are obtained.)

可以用Matlab画坐标系，使用比较方便。(Coordinate system using Matlab painting, more convenient to use.)
