Abstract

In order to provide an efficient way to processing with limited resources, we propose a novice wavelet coder that operates with little memory usage on the portable embedded system. In order to reduce redundancy in coding process caused by repetitive scanning of wave let coefficients, the proposed coder uses a 2-D significance coefficient array (SCA) which records the bit-level information of wavelet coefficients. The 2-D SCA improves memory usage and processing speed required for image coding because it can perform significance check and bit coding of coefficients simultaneously.
