Design of FIR Filters for Fast Multiscale Directional Filter Banks

Abstract

Fast multiscale directional filter bank (FMDFB) is a multiscale image representation scheme that is suitable for several image processing applications such as image denoising, texture retrieval, and pattern recognition. It is constructed using the iterative filter structures namely Laplacian pyramid and directional filter bank. In this paper, we present the method for designing the FIR filters required to construct FMDFB. Also, we demonstrate the perfect reconstruction and critically sampled property of FMDFB.
