ecc encryption decryption image matlab

snake算法，主动几何模型，用来进行基于区域的图像分割。(snake algorithm,for image sementation。)

这是一个用Matlab程序写的模拟退火算法，用于解决旅行商问题(It s a matlab code for TSP problem using SA Algorithm)

Gridding is a method of interpolating data from an arbitrary 2D sampling pattern to a uniform grid. In MRI, this allows rapid image reconstruction. There are numerous publications on MR gridding reconstruction. The tar file includes numerous .m scripts, and C code that can be compiled to a .mex function. You will need to compile the MEX functions - in Matlab try "mex gridlut_mex.c" and "mex calcdcflut_mex.c" These should result in files gridlut_mex.mex??? and calcdcflut_mex.mex??? where ??? depends on your operating system. Run the function spiralexample.m in Matlab. (Gridding is a method of interpolating data from an arbitrary 2D sampling pattern to a uniform grid. In MRI, this allows rapid image reconstruction.

1. m-file powspec computes the powerspectrum of the input signal. 2. m-file ispecgram computes the inverse of the output of specgram

实现快速傅立叶变换的程序，是matlab下的M文件，内部还和含有一个介绍PDF文件(fast Fourier transform procedures, the Matlab M paper Internal also contains an introduction and PDF files)

分水岭分割在matlab下实现，希望大家多提意见。(watershed segmentation in Matlab achieve, we hope to do so.)

详细介绍了机器学习中非监督学习的内容、分类和方法(This document introduces the unsupervised learing of Machine learning with details.)

简易模拟时钟，使用MATLAB的GUI开发而成，可以获取桌面时钟数然后在模拟钟面上显示，每隔一秒刷新显示！(Simple analog clock, a GUI was developed using MATLAB, you can get a desktop clocks and analog clock face on display, refresh the display every second!)

小电流接地系统发生接地故障时，利用prony算法提取暂态特征分量并利用相关分析法实现选线取得很好的效果，有效的排除了干扰信号的影响，结论明显、准确性高。(When the small current grounding system occurs ground fault , we use prony algorithm to extract the transient characteristics of the component and line selection by using correlation analysis. The simulation present that the algorithm effectively eliminate the influence of interfering signal. The result has a good effect and high accuracy obviously.)
