Design and implementation of an RGB to HMMD color conversion module on FPGA

Abstract

In this paper, we propose a hardware architecture to implement a RGB to HMMD Color space converter. This converter presents a fundamental module for the color structure descriptor (CSD) extraction. The CSD provides a high satisfactory image indexing and retrieval results among all MPEG-7color-based descriptors, but the real time implementation of this descriptor still having problems. We propose a hardware implementation of the RGB to HMMD block using Field Programmable Gate Arrays (FPGAs). The proposed implementation architecture can efficiently operate under real time video processing constraints. We have used a new FPGA family to implement the proposed architecture. Synthesis and simulation results of the developed hardware module are given to demonstrate the effectiveness of the implemented architecture and to show the simulations results for a real input image.
