matlab下图文并茂的分析了fft算法，分析了如何从频谱如何看频率，相位，幅值(Here to enter through the abundant of matlab analyzed fft, and analyzed from the frequency spectrum how to see that phase, should be translated text)

刀刃法获取靶标图像的MTF,PSF.适用于遥感图像中的MTF提取。(The blade method for target images MTF, PSF. Apply to the remote sensing image MTF extraction.)

采用最小交叉熵，最大熵，OTSU阈值分割(Using minimum cross entropy, maximum entropy, OTSU thresholding)

利用最小二乘法实现图像变形,提出一种基于控制曲线集的移动最小二乘图像变形算法。根据图像的形状拓扑关系或轮廓信息设置点，生成控制曲线，移动控制曲线生成图像的仿射变换、相似变化、刚性变换。 (The technology of image deformation.Using Moving Least Squares.)

图像抠图是将图像的目标物体从背景图像分割出来的技术，这段代码是用MATLAB实现的一段抠图的代码(Image matting is the image of the target object from the background image segmentation techniques, this code is implemented using MATLAB code section of matting)

最大熵图像复原方法，效果还好，这是最近努力的结果，不过或许需要适当的改进之后会有更好的结果，分享一下(Maximum entropy image restoration method, the effect Fortunately, this is the result of recent efforts, but may need to be appropriate to improve after the better results, share)

灰度图生成程序 可以生成BMP/JPG格式的灰度图 大家可以随便使用下载(Grayscale generator can generate BMP/JPG format, you can easily use the download grayscale)

基于梯度下降的稀疏约束 NMF 算法(NMFsc)，之前pudn上也有类似的，但缺少一个程序，这里面都包括了 (Based on gradient descent sparse constraint NMF algorithm (NMFsc), before the pudn has a similar, but the lack of a program, there are included)

说明：  区域生长法的图像分割，可以较好地提取脑部图像。(The region growing method can extract brain image well.)

Perona-Malik的线性和非线性融合多尺度提边算法代码(Perona-Malik of the linear and nonlinear fusion algorithm for multi-scale edge mention code)
