چکیده

In the design of maximally decimated lter banks, conventional practice is to use Johnston lters at both the analysis and synthesis ends. This paper proposes a two-step procedure: First, select suitable Johnston lters for the analysis side for good coding of the input; then design the synthesis lters to optimize the signal to reconstructed noise ratio SNR. A detailed example shows that one can do somewhat better than Johnston lters at the synthesis end.

New S’ubband Geometries for Image Texturie Segmentation

The usefulness of multichannel filtering for image texture segmentation has been demonstrated in the literature [l, 2, 3 , 4, 5, 61. Based on psychophysical studies, it has been largely believed that Gabor filters are optimal for segmentation [7, 81. In this paper, the application of maximally decimated, non-separable, perfect reconstruction filter banks (subband systems) are investigated for t...

Report on US ARMY AWARD DAAD19-00-1-0534 Optimal Subband Coders for Cyclostationary Signals

We consider optimal orthonormal filter banks for subband coding of wide sense cyclostationary signals, with -periodic second order statistics. An -channel over decimated uniform filter bank, with -periodic analysis and synthesis filters, is used as the subband coder. An average variance condition is used to measure the output distortion. We show that for at least three potential bit allocation ...

Linear Phase Cosine Modulated Maximally Decimated Filter Banks with Perfect Reconstruction

We propose a novel way to design maximally decimated FIR cosine modulated filter banks, in which each analysis and synthesis filter has linear phase. The system can be designed to have either the approximate reconstruction property (pseudoQMF system) or perfect reconstruction property (PR system). In the PR case, the system is a paraunitary filter bank. As in earlier work on cosine modulated sy...

Two-Channel Linear-Phase FIR Filter Banks Utilizing the Frequency Response Masking Approach

The frequency-response masking (FRM) approach was introduced as a means of generating narrow transition band linear-phase FIR filters with a low arithmetic complexity. This paper proposes an approach for synthesizing two-channel maximally decimated FIR filter banks utilizing the FRM technique. Compared to conventional quadrature-mirror filter (QMF) banks, the proposed banks lower significantly ...

Theory and Design of A4-Channel Maximally Decimated uadrature Mirror Filters with Arbitrary

Based on the concept of losslessness in digital filter structures, this paper derives a general class of maximally decimated Mchannel quadrature mirror filter hanks that lead to perfect reconstrnction. The perfect-reconstruction property guarantees that the reconstructed signal f ( a ) is a delayed version of the input signal x (n), i.e., 2 ( n ) = n ( n a,,). It is shown that such a property c...
