DCT

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))

我用VC编的一个画图程序：其中使用了切分视图(I VC series a drawing program : the use of split View)

点云插值，离散点云插值，孔洞填充，使用python语言(Point cloud interpolation, discrete point cloud interpolation, hole filling, using Python language)

WaterShed图像分割方法，使用C++来编写的程序，分割效果还不错，不过要用的话，自己还是要调一下的。(WaterShed image segmentation method, using C++ to write programs, segmentation results were pretty good, but use the words that he is still would like to stress the.)

首次适应算法First Fit： 从空闲分区表的第一个表目起查找该表,把最先能够满足要求的空闲区分配给作业,这种方法目()

连续小波变换寻找脊线，用在信号处理、图像处理等方面（MATLAB）(Continuous wavelet transform for ridge line（MATLAB）)

采用自适应非局部降噪的算法对图像进行去噪处理，能够实现不同算法的降噪处理(Using adaptive non-local denoising algorithm to denoise image can achieve denoising processing of different algorithms.)

基于字典学习和矩阵低秩稀疏分解的SAR图像处理新方法，拓展了低秩稀疏分解的应用领域，有很好的应用前景。(Dictionary Learning and Low-rank Sparse Matrix Decomposition for Sparsity-driven SAR Image Reconstruction)

采用matlab代码进行超像素分割，可以很好使用，效果好(Super-pixel segmentation using matlab code can be used well and the effect is good.)

本程序是一幅512*512的lena.raw图像进行快速DCT和其逆变换，整个程序均调试通过，是在C语言环境下编写的，在整个关于快速DCT的源码中，本代码可以说是集大成者，很值得一看。(This procedure is mainly of a float or double type of data, rounding, the float data can be positive or negative, can be, take the whole principle of rounding.)
