Abstract :
The purpose of this paper is to presents an approach to extend the functionality and the application fields of the JPEG2000 image coding systems by choosing various wavelet kernels such as CDF 9/7, LT 5/3, BT 7/5a, BT 7/5b, standard 7/5, Antonini 7/5, LS 9/7 etc. This paper gives a general procedure for extending the JPEG2000 coding system by using 7/5 wavelet which includes 7/5 wavelet lifting scheme, quantization algorithm, EBCOT coding and their optimization design. Experimental results show that the compression performances of the extensible image coding system for various image properties, and various needs and requirements of the image compression are always excellent by choosing appropriate wavelet kernel. The image compression performances of the 7/5 wavelet kernel in extended JPEG2000 coding system very close to CDF9/7 wavelet kernel, and 7/5 wavelet filter have rational coefficients, so that reduces computational complexity and are suitable for implementation via VLSI than CDF 9/7 wavelet kernel
