conference on wavelet applications in signal and image processing vi
作者: Cornea, E Cornea, M Jawerth, B Univ S Carolina Dept Math Columbia SC 29208 USA
We present planar curve descriptors that allow a hierarchical representation of curves. The descriptors are based on wavelet and multiwavelet transforms and they decompose a curve into components of different scales.

conference on wavelet applications in signal and image processing vi
作者: Li, SD Ogawa, H San Francisco State Univ Dept Math San Francisco CA 94132 USA
We define and characterize a frame-like stable decomposition for subspaces in a separable Hilbert space. We call in pseudoframes for subspaces (PFFS). Properties of PFFS are discussed. A necessary and sufficient condi... 详细信息

conference on wavelet applications in signal and image processing vi
作者: Zuidwijk, RA de Zeeuw, PM Ctr Math & Comp Sci CWI NL-1090 GB Amsterdam Netherlands
Fast algorithms performing time-scale analysis of multivariate functions are discussed. The algorithms employ univariate wavelets and involve a directional parameter, namely the angle of rotation. Both the rotation st... 详细信息

conference on wavelet applications in signal and image processing vi
作者: Meyer, FG Averbuch, AZ Stromberg, JO Coifman, RR Yale Univ New Haven CT 06520 USA
The main contribution of this work is a new paradigm for image compression. We describe a new multi-layered representation technique for images. An image is encoded as the superposition of one main approximation, and ... 详细信息

conference on wavelet applications in signal and image processing vi
作者: Hebert, DJ Soundararajan, E none (United States)
We address the problem of improving the performance of wavelet based fractal image compression by applying efficient triangulation methods. We construct iterative function systems (IFS) in the tradition of Barnsley an... 详细信息

IEEE International conference on Acoustics, Speech, and signal processing
作者: Tian, J Baraniuk, RG Wells, RO Tan, DM Wu, HR Rice Univ Computat Math Lab Houston TX 77005 USA
The discrete wavelet transform (DWT) gives a compact multiscale representation of signals and provides a hierarchical structure for signal processing. It has been assumed the DWT can fairly well decorrelate real-world... 详细信息
