An exhaustive analysis of two-dimensional architectures for discrete wavelet transform in the system view is also given. The first proposed architecture is for 1-level decomposition, which is presented by introducing the categories of internal line buffers, the strategy of optimizing the line buffer size, and the method of integrating any 1-D wavelet filter. The other two proposed architectures are for multi-level decomposition. One applies the recursive pyramid algorithm directly to the proposed 1-level architecture, and the other one combines the two previously proposed architectures to increase the hardware utilization. According to the comparison results, the proposed architecture outperforms previous architectures in the aspects of line buffer size, hardware cost, hardware utilization, and flexibility. © 2005 IEEE.application/pdf703621 bytesapplication/pdfen-USDiscrete wavelet transform (DWT); Lifting scheme; Line-based method; Recursive pyramid algorithm; VLSI architectureDiscrete wavelet transforms (DWT); Lifting scheme; Line-based methods; Recursive pyramid algorithms; VLSI architecture; Algorithms; Architectural design; Bandwidth; Computational complexity; High pass filters; Low pass filters; Microprocessor chips; Optimization; Two dimensional; VLSI circuits; Wavelet transforms; Random access storagejournal article10.1109/TCSVT.2005.8483072-s2.0-23744446736http://ntur.lib.ntu.edu.tw/bitstream/246246/141447/1/33.pdf
