选择其中图像中的矩形及正方形等感兴趣区域ROI(pfop fp[d p fiope f)

文件主要是对利用压缩感知对MRI进行数据重构，重构方式是基于全变分共轭梯度法(the folder contains some Matlab codes used for applying compressed sensing(CS) in MRI. morever, these codes are based on BP-TV.)

轨迹绘制。点击鼠标左键确定轨迹典型点，点击右键结束绘制。(Trajectory drawn. Click the left mouse button to determine the trajectory of a typical point, right-click to end the drawing.)

说明：  mylsb.m是个非常完整的LSB密写源码并且密写和提取都在里面，图片我没上传，你只需要添加一个图片文件就可以了，记住图片必须是灰度图片，如果是RGB，我转换的代码也在里面很有意思哦。weipingmian.m是个提取图像位平面的程序，图片也是需要你自己加载，最后一个就是8*8块的图像DCT变换。(mylsb.m is a very complete source of LSB Steganography Steganography and extraction, and are on the inside, I did not upload pictures, you only need to add a picture file on it, remember the image must be a grayscale image, if it is RGB, I converted the code is also very interesting inside Oh. weipingmian.m is a program to extract bit-plane images, pictures, you also need to load the last one is 8* 8 DCT transformed image.)

NSC program calculates BER of NSC

说明：  BIRCH (balanced iterative reducing and clustering using hierarchies) is an unsupervised data mining algorithm used to perform hierarchical clustering over particularly large data-sets.[1] An advantage of BIRCH is its ability to incrementally and dynamically cluster incoming, multi-dimensional metric data points in an attempt to produce the best quality clustering for a given set of resources (memory and time constraints). In most cases, BIRCH only requires a single scan of the database.
