Abstract :
A parallel 9/7-tap wavelet (PA97) based on the lifting structure is introduced. Compared to the Cohen-Daubechies-Feauveau 9/7-tap (CDF97) wavelet adopted by JPEG2000, it results in smaller, faster hardware with exactly the same image compression performance, and is therefore an ideal alternative to CDF97.
