图像频域滤波，实现图像频域滤波，加深对频域图像增强的理解(Image frequency domain filtering, image frequency domain filtering, to deepen understanding of the frequency-domain image enhancement)

基于小波变换的人脸识别代码本代码对图像进行小波分解，然后又用最近邻方法实现了图像的识别。(Face Recognition Based on Wavelet Transform code-wavelet based face recognition, the code of the image wavelet decomposition, and then with the nearest neighbor method to achieve the image recognition!)

通过maketform和cp2form指令将倾斜图形通过放射变换和投影变换纠正过来(By maketform and cp2tform instructions diagonal pattern by affine transformation and projection transformation corrected)

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!)

用六种算子(分别是gabor、拉普拉斯、priwitt、robert、sobel、wallis),对三种图象进行边缘检测比较，强烈推荐哦，是本人的毕业设计中的关键程序(The six operators (respectively gabor, Laplace, priwitt, robert, sobel, wallis), images of three edge detection comparison, strongly recommend Oh, my graduation project is a key process)

矩阵 pca或者低秩方法去噪，利用svd分解，实现对图像矩阵的去噪，该方法支持对rgb图像的去噪。使用代码请 文章中表明出处，感谢。 感谢重庆市研究生科研创新项目支持，项目号CYS16183(image denoise by low-rand regularizer or pca method. the low rank is evaluted by svd, and this method is also support for rgb image.)
