将原图与一幅模板图像进行计算相关 以图像显示相关函数(The original image and a template image to calculate correlation functions related to image display)

level set分割算法的matlab实现,by Chunming Li(image segmentation based on level sets algorithm.composed by Chunming Li)

说明：  基于局部Fisher准则的非线性核Fisher辨别分析，应用于有监督的特征提取与高维数据的有效降维。(Kernel Local Fisher Discriminant Analysis for Supervised Dimensionality Reduction.)

该程序是对输入的数字图片进行特征提取，以得到图片对应的向量，从而为下一步的识别提供帮助。(The program is to input the number of picture feature extraction in order to obtain the corresponding vector images, so as to identify the next step to help.)

blkproc.m,DCHuffmanEncoding.m,ACHuffmanEncoding.m,zigzag.m,PSNR.m, 对灰度图像进行DCT变换,量化,ZigZag扫描,Huffman编解码,反量化,反DCT变换而重建图像。 其中，blkproc.m为分块DCT变换函数； DCHuffmanEncoding.m，ACHuffmanEncoding.m分别为DC和AC变换系数的Huffman码表函数； zigzag.m为ZigZag扫描函数；PSNR.m为求图像峰值信噪比函数。 Copyright 2008 Reserved @ Wang Chengyou @ Tianjin University, P.R.China.

对图像稀疏编码和字典学习有个大致的了解，以及当前的研究现状(Sparse Coding and Dictionary)

在matlab环境下对两幅图像进行配准，输出配准参数，显示配准结果(In the matlab environment for registration of two images, output registration parameters, shows the registration results)

matlab,图像分割手势，不是用摄像头的，是将图片输入进去识别使用MATLAB进行图像分割(Matlab, image segmentation gesture, not with the camera, is to input pictures to identify the use of MATLAB image segmentation)

图像处理缩放，大小随意改变，平滑处理，基于vb6.0设计(Zoom image processing, size change, smooth deal, based on the design VB6.0)
