Fast reconstruction of subband-decomposed progressively transmitted signals
We propose a fast reconstruction method for a subband-decomposed, progressive signal coding system. We show that unlike the conventional approach which requires a fixed computational complexity, the computational complexity of the proposed approach is proportional to the number of refined coefficients at each level of progression. Therefore, unrefined coefficients do not add to the computationa...
متن کاملFast Reconstruction of Subband Decomposed Signals for Progressive Transmission
In this paper we propose a fast reconstruction method for a progressive subband-decomposed signal coding system. It is shown that unlike the normal approach which contains a xed computational complexity, the computational complexity of the proposed approach is proportional to the number of reened coeecients. Therefore, using the proposed approach in image coding applications, we can update the ...

متن کاملCorrelation over Decomposed Signals: A Non-Linear Approach to Fast and Effective Sequences Comparison
A novel non-linear approach to fast and effective comparison of sequences is presented, compared to the traditional cross-correlation operator, and illustrated with respect to DNA sequences.
متن کاملSubband-domain filtering of MPEG audio signals
The cosine modulated filter bank is commonly used for the timefrequency decomposition of audio signals. For example, it is a basic element of the MPEG-1 and MPEG-2 audio coding standards. While this filter bank is not perfectly-reconstructing, it does provide for the cancelation of aliasing components that are introduced during the analysis decomposition. If the subband signals are to be proces...
