①之前修改SIFT内部函数时发现如下的size_t
size_t是无符号的,并且是平台无关的,表示0-MAXINT的范围,具体参考
② 关于resize中area和InputArray的使用
详见:

http://blog.csdn.net/yang_xian521/article/details/7755101 觉得里面的仿射变换程序错啦 没有计算y坐标啊
③openmp的功能就那么少?

暂时就那么些吧
④特征点的读写
http://blog.csdn.net/wd1603926823/article/details/48969039 实现了特征点的坐标与描述符矩阵的写
//This will store your keypoints in a file named keypoints.yml and the node containing the data is named "aNameYouLike". vector<Keypoint> mykpts; FileStorage fs("keypoints.yml", FileStorage::WRITE); write( fs , "aNameYouLike", mykpts ); fs.release(); //This will be used to read back the keypoints from the file vector<Keypoint> mykpts2; FileStorage fs2("keypoints.yml", FileStorage::READ); FileNode kptFileNode = fs2["aNameYouLike"]; read( kptFileNode, mykpts2 ); fs2.release();
参考 或看opencv读写xml、yml的规范
⑤qt入门
