This is a presentation of the work that we have done in the field of 3D spatial filtering. We have focused on the convolution with many similar Gabor filters. The results were achieved with our in-house developed LinearFilters library .

 

Motivation

The motivation for fast and accurate computation of Gabor filtering was to be able to compute certain optical flow algorithms efficiently. Such group of algorithms employ multiple regularly spaced and oriented Gabor filters -- filter banks. The filtering has always been the major slowdown factor of the approach.

The overall goal is to equip such methods with fast and accurate implementation of algorithms which should be able to compute truly arbitrary, i.e. anisotropic with generaly-oriented main axis, Gabor filtering for 3D and time lapse 3D images. The LinearFilters library should serve this purpose.
