实现了图像的加水印，去噪，加噪声等功能，部分实现了追踪测速迭代松弛算法，独立成分分析算法降低原始数据噪声。( Realize image watermarking, de-noising, plus noise and other functions, Partially achieved tracking speed iterative relaxation algorithm, Independent component analysis algorithm reduces the raw data noise.)

亚像素边缘检测，对图像的边缘检测达到亚像素级别(Sub-pixel edge detection, image edge detection to sub-pixel level)

冈萨雷斯第三版 10.3.6节 关于双 ostu阈值处理的算法(digital image processing,third edition the code about two ostu threshold processing)

说明：  将小波和各向异性扩散结合，对超声图像进行去噪。效果较好(The combination of wavelet and anisotropic diffusion for ultrasonic image denoising. Better)

图像重采样，根据新旧图像像元大小的比例进行图像的重采样，(This function resamples the images at the new grid points defined by the new pixel sizes. It assumes that intensities are defined at the pixel centers)

图像的读入，放大，cany检测，二值化，灰度化，任意角度旋转(Read image, zooming, cany detection, binarization, gray, and arbitrary rotation angle)

计算图像处理中的评价指标NPCR和UACI(Calculate the evaluation indexes NPCR and UACI)

说明：  OFDM中的降低PAPR中的pts方法的程序，里面包括随机，交织，相邻分割(it is a simulation papr of pts)

实现了一个基于颜色、纹理、形状综合特征的MatlabGUI图像检索系统。(Bulit an image retrieval system based on which combines these three features and realizes user-defined weights.)
