A study on improvement of SPIHT algorithm using redundancy bit removing
중복비트 제거를 이용한 SPIHT알고리즘의 개선에 관한 연구
Abstract
This paper presents compression rate improvement for SPIHT algorithm though redundancy bit removing. Proposed SPIHT algorithm uses a method to select of optimized threshold from feature of wavelet transform coefficients and removes sign bit if coefficient of LL area. Experimental results show that the proposed algorithm achieves more improvement bit rate and more fast progressive transmission with low bit rate.
