FBOW (Fast Bag of Words) is an extremmely optimized version of the DBow2/DBow3 libraries.
Hello @rmsalinas @shinsumicco , When creating my own vocabulary I noticed that the weight of all nodes is the same (1) and that creating a BoW vector just counts the...
Hi, Does the words "Not yet implemented indexing of images" means that it can not support ORB-SLAM2, which needs invert index from descriptor to image, for the moment?
I've noticed that the weights of the words in the fbow map are computed without any form of normalization. https://github.com/rmsalinas/fbow/blob/e148dbcbd8ee1976b1b07988b5761a9171b9f01a/src/fbow.h#L434 What's more, it appears that the vocabulary itself is not...
 If I want to change the size the descriptor from 128 bytes to 256 bytes,how should I do?
Wanted to check if there is an option to create a database from a set of images using an existing vocabulary and then query the database for matches with test...

Hello @rmsalinas @shinsumicco , I had to test DBoW2, DBoW3, and FBoW, and I didn't understand something important. On DBoW2, a demo.cpp code has been provided with a dataset of...
I added and modified database from DBow3. Check fbow_demo with argument "orb ../../utils/images/image0.png ../../utils/images/image1.png ../../utils/images/image2.png ../../utils/images/image3.png"
