Contourlet

说明：  四叉树程序，图像处理，要做这个的可以看看(Quadtree procedures, image processing, that can do this look)

本程序为图像锐化的经典程序，源码里有详细的标注。(the procedures for sharpening images of the classic procedures are detailed source of tagging.)

de-speckling of noise in medical ultra sound images...

时域Gabor 滤波器 函数，需要用Gabor滤波器进行特征提取的可以用(spatial gabor filter)

快速剪切波变换的源程序，用于图像处理，运行速度快(Fast shear wave transform source, used for image processing, fast running)

说明：  根据：基于不变矩特征和神经网络的图像模式模糊分类 论文 在matlab上做的实验，有7个不变矩生成和神经网络分类的代码，还要论文原文(According to: Based on the characteristics of moment invariants and neural network image mode fuzzy classification papers in matlab to do the experiment, there are seven moment invariants and neural network classifier to generate the code, but also the original papers)

利用四元数对彩色图像进行各种图像处理的，如滤波、快速傅立叶变化、图像质量评价等。(Use quaternion various images for color image processing, such as filtering, fast Fourier transform, the image quality evaluation.)

bandelet 去噪，包含blsgsm和平移不变去噪，不过对大图像需要的内存比较大(bandelet denoising, including blsgsm and translation invariant denoising, but for large images need more memory)

角点检测程序，能够标记出图像中的角点。角点检测是图像匹配对第一步(corner detection procedures can mark up images of the corner. Corner detection is the first step in image matching)

一种新型的图像去噪方法，相较于已有的算法，优势在于较小的计算量以及相对更好的还原效果。(A new image denoising method, compared to the existing algorithms, the advantages and the relatively small amount of computation better reproduction.)
