Angular modulation
A Matlab implementation of the angular modulation proposed in our ECCV 2014 paper. It implements modulation of VLAD, modulation of monomial embedding, and the trigonometric polynomial for efficient similarity computation of multiple rotations.

Selective match kernels
A Matlab/Mex implementation of the ASMK* variant (good compromise accuracy/speed/memory) is available here. The method is described in this paper.

Hough Pyramid Matching for Large Scale Image Retrieval
Binary code which implements the method described in our paper for large scale image retrieval. See the project page.
