说明：  运用低通滤波器，中心削波和自相关技术估计一段男性和女性语音信号的基音周期，画出基音轨迹曲线，给出估计准确率。(The use of low-pass filter, the center clipping and related technologies is estimated from a male and female speech signal pitch period, pitch trajectory drawn curves of estimated accuracy.)

说明：  图像识别的matlab程序实现，基于神经网络的图像识别(Image recognition matlab program implementation, image recognition based on neural networks)

基于象素的图像配准程序,要配准的两幅图像,通过多对对控制点来配对(Pixel-based image registration procedures are based on the registration of two images, through a multi-right right control point to the matching)

是图像处理中常用的测试图库，非常实用,如lena图片， 青椒图片，以及zelda图片等(is the test pictures used in image processing very useful)

用于求解凸优化问题，恢复低秩密度矩阵问题(this matlab Algorithm can be used for the convey optimal problen, and also for the low-rank density matrix reconstruction)

说明：  灰度图像异或加密，函数需要输入一个要加密的图片，图片的灰阶以及一个伪随机比特流(Gray image XOR encryption, the function needs to input a picture to be encrypted, the gray scale of the picture and a pseudo-random bit stream)

实例如图所示

我自己写的用hilbert曲线扫描图像后，进行图像检索的代码，里面有很多有用的代码，有部分是在国外网上淘的(I wrote it myself using hilbert curve scanned image after image retrieval code, which has many useful code, some of the Amoy abroad online)

车辆检测跟踪,采用matlab编程，可对车辆进行目标跟踪与检测(Vehicle detection and tracking)

N-FINDR算法，高光谱图像无先验知识下的端元提取算法，最后计算每种端元的丰度(N-FINDR algorithm for hyperspectral image without prior knowledge of endmember extraction, and calculate the abundance)
