4th conference on wavelet applications in signal and image processing
作者: Rue, F Bijaoui, A OBSERV COTE AZUR URA CNRS 1360DPT CERGAF-06304 NICE 4FRANCE
A multiscale vision model based on a pyramidal wavelet transform is described in the present paper. The pyramidal wavelet algorithm is modified in order to satisfy a correct sampling at each scale. Objects are defined... 详细信息

作者: Mehta, S Powers, EJ Park, IS UNIV TEXAS DEPT ELECT & COMP ENGNAUSTINTX 78712
The objective of this paper is to investigate and provide insight into wavelet-based higher-order time-scale analysis, with an emphasis on the third-order statistic, the bispectrum. We also use a wavelet-based higher-... 详细信息

作者: Keinert, F Kwon, SG IOWA STATE UNIV SCI & TECHNOL DEPT MATHAMESIA 50011
The accuracy of the wavelet approximation at resolution h equals 2-n to a smooth function f is limited by O(hn), where N is the number of vanishing moments of the mother wavelet (psi) . For any positive integer p, we ... 详细信息

作者: Li, JM Jin, JS UNIV NEW S WALES SCH COMP SCI & ENGNSYDNEYNSW 2052AUSTRALIA
An image compression method based on wavelet transforms and the human visual system (HVS) is presented in this paper. In the proposed method, we emphasize on the issue of designing a quantizer for wavelet transform co... 详细信息

作者: Aldroubi, A NIH BIOMED ENGN & INSTRUMENTAT PROGRAMBETHESDAMD 20892
Orthogonal, semiorthogonal and biorthogonal wavelet bases are special cases of oblique multiwavelet bases. One of the advantage of oblique multiwavelets is the flexibility they provide for constructing bases with cert... 详细信息

作者: Klappenecker, A Baumgarte, V Nuckel, A Beth, T UNIV KARLSRUHE INST ALGORITHMEN & KOGNIT SYSTD-76128 KARLSRUHEGERMANY
We investigate three approaches to VLSI implementation of wavelet filters. The direct form structure, the lattice form structure, and an algebraic structure are used to derive different architectures for wavelet filte... 详细信息

4th conference on wavelet applications in signal and image processing
作者: Rahman, ZU COLL WILLIAM & MARY WILLIAMSBURGVA 23187
The performance of wavelet compression algorithms is generally judged solely as a function of the compression ratio and the vidual artifacts which are perceivable in the reconstructed image. The problem then becomes o... 详细信息
