主要是对视网膜图像进行血管分割，效果还不错(Primarily on retinal vascular image segmentation, the effect was not bad)

yuv420 to_yuv420p 程序(yuv420 to_yuv420p )

关于图像配准中的交叉相关的实现，可以直接调用。(About Image Registration in the implementation of cross-correlation can be directly called.)

说明：  实现了图像与视频的信息隐藏，输入图片和视频可进行效果演示(The information hiding of image and video is realized)

图像经过Contourlet变换后，加水印(After Contourlet transform images, add watermark)

使用二维双密度小波2-D Double-Density DWT Thresholding Method，决定图像滤波门限值，实现图像去噪处理。(use of two-dimensional density Wavelet 2-D Double-Density DWT Thresho lding Method, the decision threshold image filtering, image denoising.)

矩阵卷积的几种版本：conv函数，矩阵乘法形式，纯矩阵乘法形式(Several versions of matrix convolution: convolutional vision, matrix vision, only-matrix vision)

室内定位的源码，基于指纹定位的算法，把指纹存储在数据库在，然后在在线阶段根据收到的wifi信号，蓝牙信号，手机基站信号作为一个向量与数据库中存储的指纹匹配，匹配距离最短的就是指纹数据对应的位置(Indoor positioning source, location-based fingerprint algorithm, fingerprint stored in the , then in the online stage according wifi signal, Bluetooth signals, cell phone base station signals received as a vector in the matches the stored fingerprint, matching the shortest distance is a position corresponding to the fingerprint data)

matlab图像处理中经典图片，包括lena，baboon，等(MATLAB image processing classic pictures, including Lena, baboon, etc.)

基于纹理分析的图像分割，matlab开发，用entropyfilt，stdfilt等(Image segmentation based on texture analysis, matlab development, with entropyfilt, stdfilt etc.)
