This paper proposes a novel algorithm to compute the 2-D discrete wavelet transform (DWT)
of high-resolution (HR) images on low-cost visual sensor and Internet of Things (IoT) nodes …

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 …

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 …
