Abstract

Lifting structures and rounding operations are main tools to construct integer wavelet transforms (IWT) that are well applied in lossless/lossy compression. However, the rounding operation generates its non-linear noise that makes its performance worse. In this report, we propose a new optimum-rounding 5/3 IWT based on 2-level decomposition for lossless/lossy image compression. Our proposed 5/3 IWT is designed to reduce rounding operation as much as possible. Filter characteristics of our proposed 5/3 IWT are the same as the conventional 2-level 2D 5/3 IWT excluded rounding effect. Coding performances of the proposed 5/3 IWT are better than those of conventional 5/3 IWT in lossy performance, because of reduction of rounding effects. Especially, its performance in near lossless compression is much better than the conventional one. However, they have almost the same lossless performance. Simulation results confirm effectiveness of our proposed 5/3 IWT.
