How to update Surf descritor Map dynamicaly

asked 2013-06-10 07:11:53 -0500

Hi,

To make better SURF detection, i need to aggregate results coming from different good matches to save only those who are working.

After finding the first good SURF detection (keypoints and descriptors), i need to update these data. I cannot find how to do it for the Mat descriptor object.

Do you have any exemple of how to do this.

Thanks

You can either create a new matrix and copy the old and new descriptors to it or you can use push_back(new_descriptor_matrix) to your old descriptor-matrix and append the new descriptors at the end of it (of course this only works it the descriptor-size == number of columns doesn't change).
