Flexible allocation approach for GPU implementation of 2D IIR filters in satellite images processing

Abstract

This paper considers a GPU implementation of a two-dimensional infinite impulse-response filter. The presented flexible allocation approach makes it possible to efficiently implement the polytope model in a single GPU kernel. Some theoretical performance estimations of the proposed flexible allocation algorithm are given in the paper. The proposed IIR filtering technique is efficient when applied to de-blurring satellite images of large size.
