Advanced_extracting_algorithm_for_edge_feature_poi
: 对一种基于图像几何重心的特征点提取算法进行了改进 改进后的算法可以提取任何边缘线上凹凸处的特征点 其基本
思想是,首先提取图像的边缘轮廓线,计算封闭边缘线和非封闭边缘线的几何重心 然后以重心为极点,对边缘点极坐标化,形成
幅角-极径曲线,在该曲线上寻找局部极大极小值点 最后根据局部非极大(小)抑制原则对极大(小)值点进行取舍获得特征点 模
拟结果表明算法计算简单 稳定性好 该方法提取的特征点能准确地反映目标的形状,对目标的识别 跟踪以及三维表面重建等都
具有重要的价值(This paper modifiesakindoffeatureextractingalgorithmbasedonimageedge.First, imageedgeoutlineisextracted.

说明: 置信度传播立体匹配,matelab就能运行,比较简单
1、需要Matlab 2013a及以上版本;
2、运行demo_stereo.m,注意修改图片路径;
3、左右图像使用3通道灰度图;(Confidence propagation stereo matching, MATELAB can run, relatively simple
1. Matlab 2013a and above is required;
2. Run demo_ Stereo. M, pay attention to modifying the image path;
3. The left and right images use 3-channel gray-scale images)
