Simplegabor - Multiresolution Gabor Feature Toolbox


This package contains a Matlab toolbox for multiresolution Gabor filtering of 2-D signals (images). The implementation is intended to be as efficient as possible within limitations of Matlab. This toolbox replaces an older Gabor filtering toolbox.

Version 0.2.2 includes only frequency domain filtering. Spatial domain filtering would be faster in some cases, namely when filter responses are needed only for some points and not for all of the image. As of version 0.2.1 the toolbox no longer requires statistics toolbox.
