Performance Comparison of Three Arithmetic of Lifting Wavelet Transform

Dimensional discrete wavelet transform(DWT) is becoming one of the standard tools for audio and image signal processor,the 5/3 and 9/7 filter-pairs included in JPEG-2000 was considered for lossless and lossy image compression,instead of based on DCT image compression and improved using lifting scheme.This paper proposes three arithmetic based on lifting scheme of two-dimensional discrete wavelet transform(2D DWT) and compare with respect to their performance on a very long instruction-word(VLIW) digital signal processor(DSP).Here,we choose various image sizes usually using in compression.The experimental results show that each realization can reduce the amount of time requirement and performs better for different points of the parameter space.
