Application of the Fourier-Mellin transform to translation-, rotationand scale-invariant plant leaf identification

用以图像分类，可以设计自己的数据集训练模型(For image classification, you can design your own data set training model)

Graph Cutshi是最近在计算机视觉中研究和应用比较多的优化算法，典型的用于stereo matching, image restortion, texture synthesis等应用，以上代码给出了graph cut，mean shift, 以及相关的ppm/pgm图像借口，本来是用于stereo matching的，已经把相关的matching的实现代码给去掉了。大家可以以此为平台做一些相关的研究和应用。 (Graph Cutshi recently in computer vision research and application of a relatively large number of optimization algorithms, typical for the stereo matching, image restortion, texture synthesis applications, the above code gives the graph cut, mean shift, and the associated ppm/pgm images an excuse, it is used for stereo matching, and has been related to matching the code to realize removed. U.S. can also be used as a platform to do some related research and applications.)

超像素分割图像，将彩色图像转化为CIELAB颜色空间和XY坐标下的5维特征向量，然后对5维特征向量构造距离度量标准，对图像像素进行局部聚类的过程(simple linear iterativeclustering)

说明：  图像拼接 采用SIFT+RANSAC的特征匹配方法实现图像拼接(Image mosaic is realized by SIFT + RANSAC feature matching method)

meanshift 图像分割及平滑 包括meanshift的论文及ppt(Code for the Edge Detection and Image Segmentation system and the paper)

基于模板匹配的另一种人脸识别的算法，很实用，利用肤色建模来建立人脸皮肤模型(Another based on template matching algorithm for face recognition, very practical, using skin color modeling to create a human face skin model)

很好的点云滤波的文章，主要介绍了K-d树的滤波方法(Good point cloud filtering articles, Kd tree filtering method)

小波分解，db4小波分解，分解为4层，可以直接运行(Wavelet decomposition, db4 wavelet decomposition, decomposition level of three layers, can be directly run)

说明：  svm 图像分割 用kmeans得到两类分割的图，在显示的图像中用鼠标取点得到2*num个坐标位置的二维向量，前num个为正样本，后num各为负样本(image segmentation)
