德国MVTec公司开发的HALCON机器视觉开发软件,提供了许多的功能,在这里我主要学习和研究了其中的形状匹配的算法和流程。HDevelop开发环境中提供的匹配的方法主要有三种,即Component-Based、Gray-Value-Based、Shape-Based,分别是基于组件(或成分、元素)的匹配,基于灰度值的匹配和基于形状的匹配。这三种匹配的方法各具特点,...
1、使用程序自带图片进行roi裁剪 2、将 std::vector<int> T; T.push_back(4); T.push_back(8); line2Dup::Detector detector(50, T); 特征数量改为50 3、打开vs的openMP支持 没有其他任何改动,最后的匹配时间为,基本都在122ms左右。这个时间应该不对吧 Owner meiqua commented Nov 14, 2019 vs需要...

5. Shape Matching using Hu Moments As mentioned earlier, all 7 Hu Moments are invariant under translations (move in x or y direction), scale and rotation. If one shape is the mirror image of the other, the seventh Hu Moment flips in sign. Isn’t that beautiful?
