Wavelet transform is being widely used in classical image processing. One-dimension
quantum wavelet transforms (QWTs) have been proposed. Generalizations of the 1-D QWT …

In this paper, we have proposed a design strategy for the derivation of memory-efficient
architecture for multilevel 2-D DWT. Using the proposed design scheme, we have derived a …

The classical wavelet transform has been widely applied in the information processing field.
It implies that quantum wavelet transform (QWT) may play an important role in quantum …

We have suggested a new data-access scheme for the computation of lifting two-
dimensional (2-D) discrete wavelet transform (DWT) without using data transposition. We …

In this paper, we present a novel memory-efficient high-throughput scalable architecture for
multi-level 2-D DWT. We studied the existing DWT architectures and observed that data …

When working with the line-based wavelet transform, JPEG2000 needs to buffer many sub-
band lines for future block coding. This coding buffer occupies the majority of the memory …

In this brief, we propose a new parallel lifting-based 2-D DWT architecture with high memory
efficiency and short critical path. The memory efficiency is achieved with a novel scanning …

In this article, a novel approximate hybrid multiplier design is proposed to reduce the data-
path width of lifting 2-D discrete wavelet transform (DWT) especially for wireless visual …

This paper proposes a low memory architecture of fractional wavelet filter for computing two-
dimensional discrete wavelet transform of gray-scale images. The proposed architecture …

This article proposes a fractional wavelet filter (FrWF)-based 2-D discrete wavelet transform
(DWT) architecture for the 9/7 Cohen–Daubechies–Feauveau (CDF) filter employed at the …
