2013-04-16 21:20:06 -0600 | commented answer | When does the training exactly takes place in FlannBasedMatcher in OpenCV? True. This is the line where index is built: flannIndex = new flann::Index( mergedDescriptors.getDescriptors(), *indexParams ); |

2013-02-23 22:41:11 -0600 | asked a question | When does the training exactly takes place in FlannBasedMatcher in OpenCV? The following code is in C++ and I am using OpenCV for my experiment. Suppose I am using kd-tree (FlannBasedMatcher) in the following way: In the above code it seems that training takes place (i.e. kd-tree is built) on calling the train() function. But here is the catch, if we look inside the train() function: Both of these operations (setting training descriptors and flann index, I have already done before calling train()). So when exactly is the kd-tree built? |
