作者: I.M. Po Y. Zhang K.W. Cheung C.H. Cheung CityU Image Processing Laboratory Department of Electronic Engineering City University of Hong Kong Hong Kong China Department of Planning Developing & Importing Guangdong Posts and Telecommunications Guangzhou China
A novel wavelet subtree partitioning algorithm is proposed, which divides a subtree into scalar quantized wavelet coefficients and a fractal coded sub-subtree. Based on this new technique, a variable size wavelet subt... 详细信息

SPIE conference on Acquisition, Pointing, and Tracking
作者: Wang, S Chen, G Knight, T ID Vis Inc Gainesville FL USA
Tracking multiple targets in a cluttered environment using Eletro-Optical(EO) and Infrared (IR) imagery is Important to airborne video surveillance (AVS). However, existing systems often fail when a target encounters ... 详细信息

International conference on Acoustics, Speech, and signal processing (ICASSP)
作者: S. Masud J.V. McCanny DSiP Laboratories School of Electrical Engineering and Computer Science Queen''s University Belfast Ireland Queen's University Belfast Belfast Belfast GB
In this paper we assess the relative merits of various types of wavelet functions for use in a wide range of image compression scenarios. We have delineated different algorithmic criteria that can be used for wavelet ... 详细信息

IEEE International conference on image processing
作者: M. Helsingius T. Tran T. Nguyen Department of Electrical and Computer Engineering University of Wisconsin Madison WI USA
The popular EZW (embedded zerotree wavelet) and its improved version SPIHT (set partitioning in hierarchical trees) are high-performance progressive transmission image coders based on the wavelet transform which gives... 详细信息

International conference on Acoustics, Speech, and signal processing (ICASSP)
作者: J.G. Apostolopoulos J.S. Lim Research Laboratory of Electronics Massachusetts Institute of Technology Cambridge MA USA
Transform/subband representations form an important element of many signal processing algorithms and applications. Until recently, representations have typically been designed for signals with convenient supports, e.g... 详细信息

7th Storage and Retrieval for image and Video Databases conference
作者: Schonfeld, D Lelescu, D Univ Illinois Dept EECS Signal & Image Res Lab Chicago IL 60680 USA
In this paper, we present topics related to tracking of video objects in compressed video databases in the context of video retrieval applications. We developed a video retrieval and tracking system (VORTEX) to enable... 详细信息

International conference on Acoustics, Speech, and signal processing (ICASSP)
作者: D. Nister C. Christopoulos HF/ETX/PN/XML CLAB Ericsson Telecom AB Stockholm Sweden
An embedded DCT-based image coding algorithm is described. The decoder can cut the bitstream at any point and therefore reconstruct an image at lower rate. The quality of the reconstructed image at this lower rate wou... 详细信息

作者: Mingqi Kong J.-P. Leduc B.K. Ghosh J. Corbett V.M. Wickerhauser Department of Systems Science and Mathematics Washington University of Saint Louis Saint Louis MO USA Department of Mathematics Washington University of Saint Louis Saint Louis MO USA
This paper addresses the problem of estimating, analyzing and tracking objects moving with spatio-temporal rotational motion (spin or orbit). It is assumed that the digital signals of interest are acquired from a came... 详细信息

European signal processing conference (EUSIPCO)
作者: Charles D. Creusere Naval Air Warfare Center Weapons Division China Lake CA US
An embedded coding algorithm creates a compressed bit stream which can be truncated to produce reduced resolution versions of the original image. This property allows such algorithms to precisely achieve fixed bit rat... 详细信息

International conference on Acoustics, Speech, and signal processing (ICASSP)
作者: J.M. Lewis C.S. Burrus Electrical and Computer Engineering Department Rice University Houston TX USA
We describe a generalized scale-redundant wavelet transform which approximates a dense sampling of the continuous wavelet transform (CWT) in both time and scale. The dyadic scaling requirement of the usual wavelet tra... 详细信息
