Abstract :
Based on a lifting scheme and the construction theorem of biorthogonal wavelets, we propose a new symmetric biorthogonal 9/7-tap wavelet called LS97. Compared to Cohen-Daubechies-Feauveau 9/7-tap (CDF 9/7-tap) wavelet adopted by JPEG2000, when the new wavelet is applied to image coding, the compression performance is exactly the same as that of the CDF 9/7-tap wavelet, while computational complexity is reduced remarkably
