[Wavelet] 10.1.1.139.6915

Description: PERCEPTUAL OPTIMIZATION OF WAVELET IMAGE COMPRESSION NASA’s extensive image compression requirements may be met in part by the use of wavelet techniques.1 Wavelets form a large class of signal and image transforms, generally characterized by decomposition into a set of self-similar signals that vary in scale and (in 2D) orientation.2 The Discrete Wavelet Transform (DWT) is a particular member of this family which operates on discrete sequences, and which has proven to be an effective tool in image compression.

[Wavelet] dtcwt_toolbox4_3

Description: One of the advantages of the dual-tree complex wavelet transform is that it can be used to implement 2D wavelet transforms that are more selective with respect to orientation than is the separable 2D DWT. There are two versions of the 2D dual-tree wavelet transform: the real 2-D dual-tree DWT is 2-times expansive, while the complex 2-D dual-tree DWT is 4-times expansive. Both types have wavelets oriented in six distinct directions.

[Other] A memory and area‑efficient distributed arithmetic based modular VLSI architecture of 1D/2D reconfigurable 9/7 and 5/3 D

Description: In this article, we have proposed the internal architecture of a dedicated hardware for 1D/2D convolution-based 9/7 and 5/3 DWT filters, exploiting bit-parallel ‘distributed arithmetic’ (DA) to reduce the computation time of our proposed DWT design while retaining the area at a comparable level to other recent existing designs. Despite using memory extensive bitparallel DA, we have successfully achieved 90% reduction in the memory size than that of the other notable architectures. Through our proposed architecture, both the 9/7 and 5/3 DWT filters can be realized with a selection input, mode. With the introduction of DA, we have incorporated pipelining and parallelism into our proposed convolution-based 1D/2D DWT architectures. We have reduced the area by 38.3% and memory requirement by 90% than that of the latest remarkable designs. The critical-path delay of our design is almost 50% than that of the other latest designs. We have successfully applied our prototype 2D design for real-time image decomposition. The quality of the architecture in case of real-time image decomposition is measured by ‘peak signal-to-noise ratio’ and ‘computation time’, where our proposed design outperforms other similar kind of software- and hardware-based implementations.
