Description

libCRFH - Library for Building Composed Receptive Field Histograms
The libCRFH is an open-source package that consists of a C++ library and an application (crfh-extract) for building Composed Receptive Field Histograms (for a description of CRFHs, see below). libCRFH allows to build histograms of various dimensionality computed from several image descriptors at several different scales. Currently the following descriptors are implemented:
- luminance channel L
- first-order Gaussian derivatives Lx, Ly
- second-order Gaussian derivatives Lxx, Lxy, Lyy

The generated histograms are saved to a file using a sparse format compatible with the libsvm library.

The CRFHs were applied in the context of place classification e.g. in the following work:

A. Pronobis, O. Martínez Mozos, and B. Caputo. SVM-based discriminative accumulation scheme for place recognition. In Proceedings of the IEEE International Conference on Robotics and Automation (ICRA08), Pasadena, CA, USA, May 2008.
