TV算法图像处理。total variation减少图像噪声算法源代码(TV algorithm for image processing. total variation image noise reduction algorithm source code)

基于差值的可逆水印算法源码，及详解说明。还包括一篇英文论文和该作者的一些理解和解释，希望对大家有帮助(Reversible watermarking algorithm based on difference of source code, and the Detailed Description. Also includes an English papers and some of the author' s understanding and interpretation, we hope to help)

该上传的256张CT图片是高质量的DICOME格式人类头骨的连续序列切片图，可直接用于医学三维重建或体绘制。(The upload of 256 CT images are of high quality DICOME form a continuous sequence of the human skull slice diagram can be directly used in medical 3D reconstruction or volume rendering.)

说明：  实现信号的小波分解，绘制小波不同尺度下的信号分解图形，同时去除噪声，实现信号的小波重构(The realization of the wavelet decomposition of signals, mapping at different scales of wavelet signal decomposition graphics, while removing noise, the realization of the signal wavelet reconstruction)

说明：  按照最邻近原则把待分类样本点分到各个簇。然后按平均法重新计算各个簇的质心，从而确定新的簇心。一直迭代，直到簇心的移动距离小于某个给定的值。(According to the nearest neighbor principle, the sample points to be classified are divided into clusters. Then the centroid of each cluster is recalculated according to the average method to determine the new cluster center. Iterate until the moving distance of the cluster center is less than a given value)

本代码用于实现.nc文件的IDL代码打开，并且可以实现，根据经纬度找到相应的像元值(This code is used to implement. Nc file IDL code open, and can be implemented, according to the longitude and latitude as yuan values can be found)

适用于Matlab的图像拼接，图形配准等(Matlab applied to the image mosaic, image registration, etc.)

利用matlab实现Patchwork算法，包括各种处理攻击(Using matlab Patchwork algorithm, including the attack of various treatment)

click energie of image , we can use it to calculate markov field ... and other

This matlab code is used to encode and decode digital still images into Jpeg2000 format
