Dyadic frames of directional wavelets as texture descriptors
Dyadic frames of directional wavelets as texture descriptors
收藏 引用
Conference on wavelet applications in signal and image processing viii
作者: Menegaz, G Rivoldini, A Thiran, JP Swiss Fed Inst Technol Biomed Imaging Grp CH-1015 Lausanne Switzerland
We propose a wavelet-based texture classification system. Texture descriptors are local energy measures within the feature images obtained by projecting the samples on Dyadic Frames of Directional wavelets. Rotation i... 详细信息

Conference on wavelet applications in signal and image processing viii
作者: Hogan, JA Lakey, J Univ Arkansas Dept Math Sci Fayetteville AR 72701 USA
We investigate several issues surrounding the general question of when a function in a finitely generated shift invariant subspace of L-2(R) can be determined by certain of its sample values just as a function bandlim... 详细信息

The Curvelet Transform
收藏 引用
IEEE signal processing MAGAZINE 2010年 第2期27卷 118-133页
作者: Ma, Jianwei Plonka, Gerlind Tsinghua Univ Inst Seism Explorat Beijing Peoples R China Univ Duisburg Essen Essen Germany INRIA Grenoble Grenoble France Ecole Mines Paris Paris France
Multiresolution methods are deeply related to image processing, biological and computer vision, and scientific computing. The curvelet transform is a multiscale directional transform that allows an almost optimal nona... 详细信息

IET image processing 2021年 第5期15卷 1072-1082页
作者: Sevcenco, Ioana Agathoklis, Panajotis Univ Victoria Dept Elect & Comp Engn Victoria BC V8P 5C2 Canada
This paper presents a new method for light field applications such as content replacement and fusion in the gradient domain. This approach is inspired by successful gradient domain based image and video editing techni... 详细信息

收藏 引用
Conference on wavelet applications in signal and image processing viii
作者: Dinsenbacher, T Rohde, G Hardin, D Vanderbilt Univ Nashville TN 37240 USA
When performing registrations, it is often crucial to maintain certain structure of the template data T-the data being deformed into the subject data S-as well as to keep the deformation field smooth. Current approach... 详细信息

Conference on wavelet applications in signal and image processing viii
作者: Lee, TC Lewicki, M Univ Calif San Diego Inst Neural Computat La Jolla CA 92093 USA
We are interested in learning efficient codes to represent classes of different images. The image classes are modeled using an ICA (independent component analysis) mixture model that assumes that the data was generate... 详细信息

Audio signal compression using circular wavelet packets
收藏 引用
Proceedings of SPIE - The International Society for Optical Engineering 1994年 2303卷 518-529页
作者: Scholl, James F. Rogovin, Daniel N. Rockwell Int. Science Cent. Thousand Oaks CA USA
We have successfully compressed audio signals using wavelet packets based on a recently developed fast wavelet transform (FWT) scheme using circular convolution with an adaptive hybrid filter/basis system. This algori... 详细信息
