图像去噪

this code is for the paper of image segmentation based on level set methods. in this paper improves Tony Chan s paper and improves the speed.

此程序计算图像的七个不变矩，提取出图像的形状特征，可用于图像检索。(This procedure of calculating the image of seven invariant moments, the shape of extracted image features, can be used for image retrieval.)

说明：  tiff图像的读取与处理，并且说明清新，有很大的帮助。(The reading and processing of the tiff image, and the description of the fresh, is of great help.)

fft去噪，及效果图。供大家参考！欢迎有需要的朋友下载参考(fft bianhuan)

使用matlab来实现图像的处理，比如直方图均衡化等等(Using matlab to achieve image processing, such as histogram equalization)

基于kalman滤波的图像目标识别的matlab代码，将运动目标从背景中分离出来(Kalman filter based on image recognition of matlab code, will be moving targets separated from the background)

进行简单的数字图像处理，用MATLAB进行图像旋转，灰度，亮度调节(Perform simple digital image processing)

matlab实现的SGM算法，我只是搬运工(SGM method on matlab, it is quite good)

给各种格式的图片或者相片加噪声 原代码 方便应用(To a variety of formats pictures or photos plus noise of the original code to facilitate their application)

基于OPENCV的SIFT特征提取与匹配算法。包含完整的从图像高斯金字塔、DOG、空间极值点提取、关键点描述、KDtree匹配等关键步骤的全部函数实现，对全面深入理解Lowe的SIFT算法有莫大帮助。程序运行前须安装（1）OpenCV: http://opencvlibrary.sourceforge.net （2）SIFT: http://web.engr.oregonstate.edu/~hess/index.html，并配置其环境参数。(OPENCV the SIFT-based feature extraction and matching algorithm. Contains a complete Gaussian pyramid from the image, DOG, space extremum point extraction, description of key points, KDtree matching key step in the realization of the full function of the comprehensive and in-depth understanding of Lowe s SIFT algorithm of tremendous help. Program to run before the installation of (1) OpenCV: http://opencvlibrary.sourceforge.net (2) SIFT: http://web.engr.oregonstate.edu/ ~ hess/index.html, and configure the parameters of their environment.)
