I'm not quite sure I understand the bag-of-visual-words representation, so I may misformulate my question.What I'm currently looking for is an open source library (possibly with python API). I give it pictures as input, and its output is a set of (sparse) features, so that I can perform my stuff base on this features. Idealy, I would like this piece of software to work without internet connection (so that I can work with it while in the plane).EDIT: I just learnt that facebook recently (summer 2016) released some of its image recognition code (namely multipathnet, deepmask and sharpmask)
Is there an open source implementation for bag-of-visual words?

There is one implementation of BoVW in openCV. You can find the documentation here :http://docs.opencv.org/2.4/modules/features2d/doc/object_categorization.html
