Image Transmultiplexing using Ramanujan Sums

摘要

Ramanujan Sums have recently aroused interest in signal processing community owing to its special properties. These sums have been used in many signal processing applications such as periodicity detection of sequences and bio molecules, filter bank design, formulation of new signal transforms, etc. In this paper, it is proposed to use Ramanujan Sums based filter banks for image transmultiplexing. Transmultiplexer filter coefficients derived by this method are integer valued and the designed filter bank obeys perfect reconstruction condition.
