rice大学CHOI写的一个关于小波域HMT模型的图像去噪算法。算法比较经典。对研究HMT模型的同行有很大参考价值。(rice university CHOI written on wavelet-domain HMT model for image denoising algorithm. Comparison of the classical algorithm. HMT model of research has great reference value counterparts.)

图像处理中的多尺度分割程序，使用matlab开发环境(Image processing procedures for multiscale segmentation)

本文主要是针对传统混合高斯模型运动目标检测算法的不足做出了一些改进(This article is for the shortcomings of traditional Gaussian mixture model moving object detection algorithm made some improvements)

利用双线性插值，获取亚像素位置的灰度值。适用于得到sift、surf得到的特征点坐标处的灰度值获取(The gray value of sub-pixel position is obtained by bilinear interpolation)

说明：  基于hessian矩阵的frangi血管增强算法(An algorithm of vascular enhancement based on Hessian matrix)

matlab中dftfilt.m文件函数源代码(Matlab dftfilt.m file function source code)

传统的相位编组，将梯度分为8个方向，对边缘检测有很好的效果。(Traditional phase grouping, will be divided into eight direction of the gradient of edge detection are very good results.)

光斑中心提取算法，在VS2010下，用opencv2.3.1编写的控制台程序，主要功能是利用hession矩阵和高斯滤波进行光斑中心点提取，里面附测试图片，提取精度为亚像素级别。(Spot center extraction algorithm, in VS2010, written by opencv2.3.1 console program, the main function is to use hession matrices and Gaussian filter for extracting the center spot, which is attached test images, the extraction accuracy of sub-pixel level.)
