FPSoC using Xilinx Zynq for medical image coding based on the quaternionic paraunitary filter banks

Abstract

In this paper, we have introduced a low-cost FPSoC for medical image coding and implemented to telemedicine applications based on the Xilinx Zynq. We have recently introduced a generalized block-lifting structure using the 2-D CORDIC algorithm as a block of 4- and 8-band linear phase paraunitary filter banks (LP PUFB) based on the quaternionic algebra (Q-PUFB) with one-regularity constraints on hypercomplex coefficients of the schemes for the lossy-to-lossless image coding. Its structure can implement the integer-to-integer transform (I-Q-PUFB). The parallel-pipelined efficient architecture (P2E_Q-PUFB) has been proposed. The low latency separable image processing is implemented in the given architecture.
