Efficient implementation of a 3-D medical imaging compression system using CAVLC

Abstract

This paper describes the design and implementation of context-based adaptive variable length coding (CAVLC) and comparative analysis of trade-off offered by integer transform (IT) and discrete wavelet transform (DWT) for three dimensional 3-D medical image compression systems. The proposed system architectures were synthesised using VHDL and implemented on Xilinx University Program XUPV5-LX110T prototyping board and processed medical volumes were also simulated in MATLAB. An in-depth performance analysis for both software and hardware implementations is presented and reveals a significant achievement.
