图像分割，二维图像分割，ostu算法，阈值分割(Segmentation, two-dimensional image segmentation, ostu algorithm, thresholding)

用matlab写的sift算法的全过程，用于提取特征点，是图像识别的一种好算法(The algrithm of sift)

自写的一种基于局部对比增强的GVFsnake图像分割方法，参考了xu的gvf，但本方法分割效果更好。(Since the writing of a local contrast enhancement based on image segmentation method of GVFsnake reference xu the gvf, but this method is better segmentation.)

双数复小波变换及其图像去噪算法。。。。。(Double the number of complex wavelet transform and image denoising algorithm. . . .)

实现了对误拍角度的矫正，基于轮廓提取以及旋转矩阵变换实现图像错误识别和矫正(It realizes the correction of misalignment angle, and realizes image error recognition and correction based on contour extraction and rotation matrix transformation.)

图像去噪，采用GUI界面形式，里面包括高斯滤波，低通滤波和理想滤波三种方法。(Image denoising, using GUI interface form, which includes Gaussian filtering, low-pass filtering and ideal filtering three methods.)

数字图像copy-move篡改检测。特征提取，相似块搜索(detection of copy-move forgery in digitial image)

) 使用分块的主成分分析方法(PCA)对人脸图像进行压缩编码。针对PCA方法计算量大的缺点,首先把问题转化成奇异值分解(SVD)问题,然后设计了特征空间的更新算法,通过递推,简化每一步计算的计算量,达到了实时编码的要求。 4) 在Windows平台下基于Video for Windows(VFW)接口开发了人脸视频图像编码和解码的实验系统,该系统实现了图像采集、图像显示、编码、解码等功能。() The use of sub-blocks of principal component analysis (PCA) on the human face image coding. PCA method for large defects, first of all the issues into a singular value decomposition (SVD) problem, and then design a feature space of the update algorithm, recursive, simplifying the calculation of the amount calculated at each step to achieve real-time encoding requirements. 4) In the Windows platform based on Video for Windows (VFW) interfaces, the human face image coding and decoding video experimental system, the system achieved image acquisition, image display, encoding, decoding functions.)

说明：  Gabor滤波器的MATLAB实现，可用于边缘检测(Gabor filter by matlab)

用所写算子进行边缘检测，对matlab自身图片进行分析，其中的suanzi.m是自定义的边缘检测算子(operator with written for edge detection, right Matlab own photo analysis suanzi.m which is the definition of edge detection operator)
