Description

在bagofwords.cpp文件下的compute函数，其中最后一个参数Mat* _descriptors是用来返回检测出keypoints对应的descriptors，但是返回结果始终为空。经过跟踪代码发现函数体中的Mat descriptors是用来保存检测的descriptors。估计原因是在Mat descriptors = _descriptors ? *_descriptors : Mat(); 而在调用compute函数时_descriptors 是不为空的，descriptors 的值应该指向 _descriptors 内存空间，不知道为什么最后结果为空。如果在函数体最后加入一条语句
if (_descriptors) {
*_descriptors=descriptors.clone();
}
函数就正常返回keypoints对应的descriptors。
