jpeg-matlab

产生正弦信号，加入高斯白噪声，并用小波方法去噪(Produce sine signals, add white gaussian noise, and wavelet denoising method )

用matlab实现三维数据的成像，绘制三维切片图。(3Ddata display 3dsilce)

JSteg隐写技术matlab实现代码--基本思想：用秘密信息比特直接替换JPEG图像中量化后DCT系数的最低比特位，但若量化后DCT系数为0或者1，则不进行处理。（DCT系数的LSB嵌入） (JSteg steganography matlab code- the basic idea: direct replacement with the secret information bits JPEG image quantized DCT coefficients in the least significant bit, but if the quantized DCT coefficient is 0 or 1, no processing. (DCT coefficients LSB embedding))

这是一个灰度图像进行哈夫曼编码的Matlab程序，包括编码和解码部分。绝对能用！(Huffman Code)

在灰度图像中进行直线检测，带实验效果图像。利用快速Hough变换，能够正确查找线段端点。(In the gray image in a straight line detection, the experiment with the effect of the image. Using fast Hough transform, to correctly segment endpoint search.)

通过基于纹理的图像修复算法对具有较大的破损区域的图像进行了修复；MATLAB代码(Texture based image restoration,MATLAB)

数字图像处理中的常用图，LEANNA图，大米图等等，超多图像。(Digital image processing in commonly used map, LEANNA maps, map of rice, etc., super multi-image.)

数字水印技术攻击试验，实现噪声、滤波、剪切、压缩、旋转攻击(Digital Watermarking attack test, realize noise, filtering, shear, compression, rotation attack)

nca,近邻成分分析，距离度量学习里常用的。(nca)

基于拉haar小波的图像增强，与传统直方图均衡化相比较，效果更好。(Pull-based haar wavelet image enhancement, with the traditional histogram equalization compared to better.)
