Abstract
Lifting based wavelet transform implementation not only helps in reducing the number of computations but also achieves lossy to lossless performance with finite precision. In this paper we first do a precision analysis for the set of seven filters proposed by the JPEG2000 verification model. We determine the precision required to implement the filters using fixed point 2's complement arithmetic for lossless as well as lossy coding. Next we propose a unified architecture for implementing this set of filters for both the forward and the inverse transform.
