conference on wavelet applications in signal and image processing V
作者: Wu, RS Yang, F Univ. of California/Santa Cruz (United States)
We study the decomposition and compression of one-way wave propagation and imaging operators using wavelet transform. We show that the matrix representation of the Kirchhoff imaging operator (Kirchhoff migration opera... 详细信息

conference on image processing, signal processing, and Synthetic Aperture Radar for Remote Sensing
作者: Datcu, M Schwarz, G German Aerosp Res Estab DLR German Remote Sensing Data Ctr DFD D-82234 Oberpfaffenhofen Germany
The wavelet transform developed during the last years into a mature and very pragmatic formalism for the analysis of the scale behaviour of signals. However, it also remains a tool to serve its very initial goal: the ... 详细信息

Proceedings of the 1997 6th International conference on image processing and its applications. Part 2 (of 2)
作者: Livens, S. Scheunders, P. Van de Wouwer, G. Van Dyck, D. RUCA Univ of Antwerp Antwerp Belgium
The wavelet paradigm is now well established and has found many applications in signal and image processing. Since also some of its precursors can be reformulated into wavelet terminology, it has become a preferred to... 详细信息

conference on wavelet applications in signal and image processing V
作者: Strintzis, MG Malassiotis, S Univ. of Thessaloniki (Greece)
Optimal mechanisms are determined for the hierarchical decomposition of wire-frame surfaces. A family of box-splines with compact support, suitable for the approximation of wire-frames is first defined, generated by a... 详细信息

We present an improved type of image pyramid based on general approximation functions. The type of pyramid proposed maintains the good properties of symmetry and consistent boundary conditions of the Haar pyramid. Mor... 详细信息

作者: Weiss, LG Sibul, LH The Pennsylvania State Univ. (United States)
Maximum likelihood detectors of narrowband, non-stationary random echos in Gaussian noise can be efficiently implemented in the time-frequency domain. When the transmitted signals have large time-bandwidth products, t... 详细信息

作者: Aiazzi, B Alparone, L Baronti, S Carla, R Mortelli, L Nello Carrara Research Institute on Electromagnetic Waves (Italy) Univ. of Florence (Italy)
In this work, a multi-resolution procedure based on a generalized Laplacian pyramid (GLP), with p : q (i.e. rational) scale factor, is proposed to merge image data of any resolution and represent them at any scale. Th... 详细信息

Let U = (U-1,..., U-d) be an ordered d-tuple of distinct commuting unitary operators on a complex Hilbert space H, and Y = {y(1),..., y(s)} a finite subset of H. Let U-Zd(Y) = {U(n)y(j) : n is an element of Z(d),j = 1... 详细信息
