In this paper, we present a VLSI architecture for separable 2-D Discrete Wavelet Transform (DWT). Based on 1-D DWT Recursive Pyramid Algorithm (RPA), a complete 2-D DWT output sch...
Abstract Polyphase channelizer is an important component of subband adaptive filtering systems. This paper presents an energy-efficient hardware architecture and VLSI implementatio...
This paper introduces a reconfigurable architecture for ensuring secure and real-time video delivery through a novel parameterized construction of the Discrete Wavelet Transform (D...
We present an efficient algorithm for nonlocal image filtering with applications in electron cryomicroscopy. Our denoising algorithm is a rewriting of the recently proposed nonloc...
We present iClusterDL, a self-organising overlay network that supports information retrieval and filtering functionality in a digital library environment. iClusterDL is able to han...
