Abstract

This paper discusses a newly developed high-speed image filtering processor, aiming at high-accuracy and high-speed isotropic filtering. The isotropic filtering is made efficient by the following features. (1) The image is sampled over the triangular lattice and processed by the hexagonal finite-impulse response (FIR) filter. (2) The filter is realized by the Fermat number transform (FNT) with hexagonal sectioning procedure. The authors describe the features, architecture and operation of the proposed system. Then the result of correcting the isotropic blur is presented, indicating that a practically sufficient accuracy is obtained.
