图像压缩相关代码，基于小波域的矢量量化算法实现图像编码功能(Image compression code image coding, wavelet-based vector quantization algorithm)

说明：  八值图像连通区域标记，为每个连通区域分配一个唯一的标号，处理后的图像按照从左到右，从上到下的顺序获得连续的标号(Binary image connected region eight marks, for each connected region a unique label distribution deal with in accordance with the image from left to right, from top to bottom order of access to continuous labeling)

Matlab的GUI中选择图像的感兴趣区域ROI(正方形和矩形)(Matlab GUI to select the image region of interest ROI (square and rectangular))

用Matlab写的投影法提取嘴唇 输入图像必须是规定大小的人脸(Written using Matlab projection extraction lips input image must be provided for the size of face)

三种图像分割法，有全局阈值otsu分割、迭代法全局阈值分割、局部阈值分割程序。(Three image segmentation method, there are global threshold otsu segmentation, iterative method global thresholding, local threshold segmentation program.)

基于感兴趣区域的图像检索。matlab的，希望对大家有所帮助。(Region of interest based image retrieval. matlab, and want to help everyone.)

说明：  提供激光雷达点云数据的读取，滤波及分类功能(LIDAR point cloud data available to read, filter and sorting functions)

斯坦福大学概率图模型课程作业，利用马尔科夫随机场进行图像分割，能运行，附有英文说明文档(Stanford University Probability Chart Model Assignment, using Markov random field for image segmentation, operation, with English documentation)

二维码形变校正，扭曲检测，初定位,边缘检测(calibration of a distorted QR code)

SIFT匹配算法，能够提取出具有尺度不变性的特征点，且能够对两幅图像进行鲁棒的匹配。(SIFT matching algorithm, able to extract with the scale invariance of the feature points, and the two images to be able to match robust.)
