Sift-Tree-File for the Vocabulary-tree

Hello

I'd like to know if someone has generated a tree-file for the vocab_tree-stack for other descriptors than only calonder. I would like to use it for loop-closing in the RGBD-Slam. The stack only provides one for calonder-desctiptors, but I'm not really happy with their perfomance, so I'm looking for a way to compare the perfomance of the tree with different descriptors.

Nikolas, in the

https://tum-ros-pkg.svn.sourceforge.net/svnroot/tum-ros-pkg/perception/objects_of_daily_use_finder/src/odu_finder.cpp

file we have done so for the SIFT feature. Look into the following function:

void ODUFinder::build_database(std::string directory).

Hello Dejan

I already used this function to create a sift-tree. I'm just not sure which (and how many) images and parameters should be used. I'm mainly working on a different approach, so I currently don't want to spend too much time with experiments on the tree generation. Therefore I hoped that someone could give me some tested tree-files. If I just generate a tree and it doesn't perform too well, I can't be sure if the approach just doesn't work for this problem, or if I just build a bad tree.
