Implementing the Discrete Wavelet Transform, which is being increasingly recognized in image/video compression standards, in hardware is highly area-consuming. In this paper, a new high-performance lifting-based architecture with optimized error vs. hardware cost is proposed for the 9-7 DWT. In the proposed architecture each constant coefficient multiplier of the conventional lifting structure is...
Discrete Wavelet Transform (DWT) is increasingly recognized in image/video compression standards, as indicated by its use in JPEG2000. The lifting scheme algorithm is an alternative DWT implementation that has a lower computational complexity. In this paper, a new high performance lifting-based architecture with optimized error vs. hardware complexity is presented for DWT. The proposed architecture...
