数字图像处理，dct频谱，低通滤波，高通滤波之后的图像。(Digital image processing, DCT spectrum, low pass filtering, high-pass filtering after the image.)

说明：  Jsteg_Mu可批量对JPEG图像进行Jsteg隐写。 Jpeg_Or 为jpeg密写的原始图像的文件夹， Jpeg_Di 为jpeg密写后密写了的图像的文件夹,code_file 为密写的文件,rate 为密写嵌入率.(Jsteg_Mu JPEG images can be batch Jsteg on steganography. Jpeg_Or jpeg steganography for the original image folder, Jpeg_Di as jpeg steganography written after the close of the images folder, code_file written document for the dense, rate for the steganography embedding rate.)

RGB 颜色选择器，可以自由选择颜色，也可以用吸管吸取屏幕颜色色值，便于程序员们开发(RGB color picker, you can choose colors freely, or you can suck the color value of the screen with a straw, which is easy for programmers to develop)

基于K均值聚类的图像分割，灰度图像分割案例，真彩图像分割案例(K-means clustering-based image segmentation, image segmentation case, the true color image segmentation case)

一个计算频率域的带通滤波器，图像处理中常用的滤波方式之一。(Computes frequency domain band filters)

用atrous小波变换与EMD算法相结合的图像融合(Combination of image fusion with atrous wavelet transform and EMD algorithm)

对三帧差法进行改进后的多帧融合差分法，改变原有提取帧的方法(Improved multi-frame to fusion difference method, a change in the original extract frames of three poor law)

基于暗通道先验理论的去雾算法，使用rgb暗通道计算大气光及透射率获得去雾图像(Since the scene radiance is usually not as bright as the atmospheric light, the image after haze removal looks dim. So we increase the exposure of J(x) for display.)

基于LDA的人脸识别技术，从ORL数据库读数据，然后从中取一部分进行训练，一部分进行测试。(This code is LDA base face recognition programme. It reads nots faces from ORL database and the rest (noc-nots) are used as test. LDA_Performance shows the recognition performance. )

采用平均图像融合算法，设计并实现基于小波变换的图像融合算法（选择同一场景的三对可见图像、红外图像或SAR图像进行试验）(Average image fusion algorithm is adopted to design and implement image fusion algorithm based on wavelet transform (three pairs of visible images, infrared images or SAR images of the same scene are selected for testing))
