Matlab 实现的带阻滤波器设计。基于高斯带阻滤波器。实现冈萨雷斯《数字图像处理》第五章的实例。(Matlab implementation of the band stop filter design. Based on Gaussian band-stop filter. Achieve Gonzalez, " Digital Image Processing" Chapter V of the instance.)

基于规格化Hough变换的天波超视距雷达检测前跟踪算法(Hough transform based on the normalized horizon radar detection and tracking algorithms)

对图像进行二值化处理的源代码，编译后的可执行文件须带参数运行),非常好的代码.欢迎使用和下载!呵呵,真的,不信下下看啊!(two pairs of images of the value of the source code, compile the executable files carry parameters run), very good code. welcome to download and use! Oh, really, do not look at the next letter ah!)

水印嵌入及多种攻击源码，源码当中有整个源码的详细说明(watermark embedding and various attacks source, which is the entire source of detailed source)

：介绍了一种基于小波变换的图像融合算法，它利用像素邻域平均梯度作为选择依据，对小 波变换后的高频系数进行选择，再逆变换完成图像融合．通过对红外热图与可见光图像的融合实验表明： 基于小波系数区域平均梯度的融合能使红外热图更加清晰，融合的图像光谱变异性较小，图像效果较好(: This paper presents a wavelet-based image fusion algorithm, which uses an average gradient of pixel neighborhood as selected on the basis of high frequency coefficients of wavelet transform to choose, and then inverse transform of image fusion. Through the infrared image and visible image fusion experiments show that: Based on the average gradient of wavelet coefficients of the regional integration of thermal infrared images can be more clarity, variability in integrated spectrum of images smaller, better image)

说明：  使用matlab做分水岭算法，分水岭算法是图像分割中常用的算法，算法的理论依据待考究，适用场景可供分析讨论。(watershed algorithm using matlab)

此程序为matlab的噪声添加程序，可添加周期函数的噪声(matlab for noise adding)

说明：  KM算法，通过对图片的像素点特征分类，实现图片杂质检测等功能(KM algorithm, through the image of the pixel classification to achieve image impurity detection and other functions)

计算指纹方向场的代码。。。。。。。。。。。。(code for computing orientation of fingerprint )
