图像分类精度评估算法

对视频图像序列使用卡尔曼滤波器生成背景。卡尔曼滤波是利用其的记忆特性，对一定时间长度的视频图像信息进行加权平均从而获得与实际背景图像近似的初始背景，同时达到滤除颗粒噪声、消除摄像机抖动的目的。

转,matlab(边界提取,链码生成,差分链码生成及频率向量生成程序)具有旋转不变性了的链码-Turn, matlab (border extraction, chain code generation, differential chain code generation and the frequency of vector generation procedure) has the rotation invariance of the chain code

This Matlab code implements an edge based geometric active contour model without reinitialization. MATLAB Release: R13SP1 This Matlab code implements the level set method in Chunming Li et al s paper "Level Set Evolution without Re-initialization: A New Variational Formulation", in IEEE Proc. of CVPR 2005. EVOLUTION.m: core function that performs level set evolution. Demo1.m: a demo for a real cell images Demo2.m: a demo for a synthetic noisy image Demo1_ManualBinaryInitial: demo for the same image in Demo1, allows manual initialization by the user Demo2_ManualBinaryInitial: demo for the same image in Demo2, allows manual initialization by the user

本程序是基于边缘的图像配准 伸用图像的边缘进行图像配准 先检测图像的边缘 选取图像中 最长的边缘 检测边缘上的角点信息 利用角点处的曲率 生成向量 自量匹配 进行图像配准

一种改进的SIFT双向匹配算法，sift是经典的旋转不变特征提取算法，本文对其匹配方式进行了改进-An improved two-way matching SIFT algorithm, sift the classic rotation invariant feature extraction algorithm, this method has been improved to its matching
