The proposed architecture is comprised of a stage-based boundary extension strategy and the shape-adaptive boundary handling units. The former could reduce the complexity of multiplexers that are introduced to solve the shape-adaptive boundary extension. The latter consists of two multiplexers and can solve the shape-adaptive boundary extension locally without any additional register. Two case studies are presented, including the JPEG 2000 default (9, 7) filter and MPEG-4 default (9, 3) filter. According to comparison results with previous architectures, the efficiency of the proposed architectures is proven. © 2005 Springer Science + Business Media, Inc.Boundary extension; Discrete wavelet transform; Shape-adaptive; VLSI architectureBinary codes; High pass filters; Image analysis; Image quality; Multimedia systems; Signal processing; Signal to noise ratio; Textures; Wavelet transforms; Boundary extension; Discrete wavelet transform; Shape-adaptive; VLSI architecture; VLSI circuitsjournal article10.1007/s11265-005-4960-42-s2.0-17444386385
