LDPC码的matlab仿真程序，希望对大家有用，不客气，(LDPC codes matlab simulation program, in the hope that useful, at worst,)

说明：  BP神经网络数字图像几何畸变矫正L-M优化算法(BP neural network LM digital image geometric distortion correction algorithm)

this code is a simple one_seeded region growing to segment the bones in MRI prostate images.

对Lena图像128*128，进行QF=50和QF=40的压缩，然后解压缩，并分别计算压缩图像的PSNR，给出图像压缩后的图像(Lena image of 128* 128,QF=50 and 40 compression, then uncompress, and calculate the PSNR compressed image, after image compression)

说明：  实现图像的分割。改程序是在matlab环境下运行的，程序中用到了k-means算法，实现的结果很不错(This is the program of image segmentation based on the following work: S. Chen, L. Cao, J. Liu, and X. Tang, "Image Segmentation by MAP-ML Estimations", submitted to IEEE Transactions on Image Processing. Note that this program was only tested on 32-bit PCs installed with Windows XP or Windows Server 2003. Since the K-means algorithm used in this program is from Matlab Statistics Toolbox, the program runs slower than when a faster K-means algorithm is used which can be obtained at http://vision.ucsd.edu/~pdollar/toolbox/doc/. The program was tested using Matlab R14 and the image processing Matlab Toolbox is required to run it.)

数字图像滤波的程序，包括散斑噪声的生成，中值，均值，Lee，Kuan滤波算法的实现，还计算了三个指标：峰值信噪比，等效视数，散斑指数。(Digital image filtering process, including the generation of speckle noise, median, mean, Lee, Kuan filtering algorithm, also calculated three indicators: the peak signal to noise ratio, equivalent number, speckle index.)

Powerline noise removal from ECG signals

matlab 混沌时间工具箱 用时需要自己更改数据(matlab chaotic time toolbox need to change the data)

This is the first tutorial of a series of image processing tutorials
