A VLSI architecture for lifting-based forward and inverse wavelet transform
TLDR
We propose an architecture that performs the forward and inverse discrete wavelet transform (DWT) using a lifting-based scheme for the set of seven filters proposed in JPEG2000. Expand

A multi-bit binary arithmetic coding technique
TLDR
We propose a new methodology for binary arithmetic coding which reduces the number of arithmetic operations significantly at the expense of a mild reduction in compression ratio. Expand
