Paper Abstract

The discrete wavelet transform (DWT) has been widely proposed for image and video compression. In many systems the DWT represents a large proportion of the codec complexity. In order to reduce the complexity, and as results manufacturing cost, it is desirable to choose filer bank which has low complexity, without compromising compression performance. This paper presents several multiplier free filter banks for use within image and video compression system. The filter banks are compared to alternative designs which are known to be well suited to image and video compression. The proposed filters offer almost identical performance with a significant reduction in complexity.
