Performance analysis and implementation method of VMF and EVMF for removing of impulse noise on FPGA

In this paper a reconfigurable hardware architecture of vector median filter (VMF) and Entropy vector median filter (EVMF) is proposed and their performance on removing impulse noise from color images is presented. Performance of the filters is measured using MATLAB 2012.a simulation tools and the hardware architecture is designed using Xilinx system generator tool supported by xlSgRoot library for hardware co-simulation. Due to the complex architecture of the VMF and EVMF and to minimize the resource consumption we used data reuse technique. The result shows that Entropy vector median filter (EVMF) is consuming more hardware resources but its noise removal efficiency better than the vector median filter (VMF).
