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.

ImagePro
本人研究生阶段做的项目,线结构光视觉传感器的标定中的激光光条中心的提取。
1、通过JPG、PCX、GIF解码方法,来打开BMP、JPG、PCX、GIF格式图像。
2、大津展之法阈值变换,效果较好。
3、三种细化方法,Rosenfold细化、Hildith细化、Pavlidis细化。
4、基于灰度重心法的全分辨率的激光光条中心亚像素坐标的提取。(Calibration )
