随机中点位移法模拟分形地形的MATLAB源代码，用于分形几何，实用！(Random midpoint displacement fractal terrain simulation of MATLAB source code for the fractal geometry, and practical!)

实现BM3d denoising的源代码。 (BM3d denoising implementation source code)

细节增强的直方图均衡法，在增强图像对比度的同时还能保留细节细心，避免了细节吞噬现象(Detail enhancement, histogram equalization, but also retained the same time enhance the image contrast details carefully, to avoid the details of phagocytosis)

Criminisi方法修复灰度图像（单通道）图像(Criminisi algorithm for gray image or single channel image )

获取灰度图像LBP特征的matlab程序，两种LBP算子(LBP to obtain the characteristics of gray image matlab procedures, both LBP operator)

说明：  使用matlab工具箱进行的图像配准，需提取特征点来实现配准(Using matlab toolbox for image registration, extraction of feature points needed to achieve alignment)

图片极坐标转换,可实现极坐标转换，以及求傅里叶变换(Picture polar coordinate conversion, convert polar coordinates can be realized, as well as seeking the Fourier transform)

说明：  小波变化是对傅里叶变换和短时傅里叶变换的一个突破，其改变就在于，将无限长的三角函数基换成了有限长的会衰减的小波。(Wavelet transform is a breakthrough of Fourier transform and short-time Fourier transform. Its change lies in that the infinite trigonometric function base is replaced by the finite attenuation wavelet.)

压缩文件是CNN卷积神经网络图像处理的数据库mnist_uint8.mat(Compressed file is the database of CNN convolution neural network image processing mnist_uint8.mat)

对图像切割成若干任意大小图像，并进行滤波平滑。(Cut image into little ones and make the little pictures more smoth ,so well ,ha ha ha .)
