International conference on image processing (ICIP-96)
作者: Gasti, W INST NATL POLYTECH GRENOBLE LAB TIRFF-38031 GRENOBLEFRANCE
Considering the forthcoming spaceborne imaging instruments, on-board image compression is now essential due to the limited on-board resources such as storage and telemetry. Meanwhile, the impact of compression on scie... 详细信息

wavelets - applications in signal and image processing X conference
作者: Dragotti, PL Vetterli, M Univ London Imperial Coll Sci Technol & Med London SW7 2BT England
In this paper, we consider classes of not bandlimited signals, namely, streams of Diracs and piecewise polynomial signals, and show that these signals can be sampled and perfectly reconstructed using wavelets as sampl... 详细信息

wavelets - applications in signal and image processing X conference
作者: Song, XM Fan, GL Oklahoma State Univ Sch Elect & Comp Engn Stillwater OK 74078 USA
In this paper, we study unsupervised image segmentation using wavelet-domain hidden Markov models (HMMs), where three clustering methods are used to obtain the initial segmentation results. We first review recent supe... 详细信息

International conference on Graphic and image processing (ICGIP)
作者: Gholipour, Morteza Noubari, Hossein Ahmadi Kamarei, Mahmoud Univ Tehran ECE Dept Tehran Iran Univ British Columbia Vancouver BC Canada
Discrete wavelet Transform (DWT) is widely used in signal processing applications. In this paper, we describe hardware implementation of a lifting-based DWT, which is used in image compression. The CDF(2,2) lifting-ba... 详细信息

1997 IEEE International conference on Acoustics, Speech, and signal processing (ICASSP 97)
作者: Boland, S Deriche, M Queensland Univ of Technology Brisbane Australia
In this paper, we propose a new combined harmonic-wavelet representation for audio where a harmonic analysis-synthesis scheme is used, first, to approximate each audio frame as a sum of several sinusoids. Then, the di... 详细信息
