Discrete biorthogonal wavelets and PR finite impulse response (FIR) filter banks via block circulant matrices
收藏 引用
Proceedings of SPIE - The International Society for Optical Engineering 1994年 2303卷 56-63页
作者: Kautsky, Jaroslav Turcajova, Radka Flinders Univ. Adelaide SA Aust
Factorization of orthogonal block circulant matrices can not be generalized in a straightforward way for block circulant matrices which are merely invertible. However, they can be decomposed into an orthogonal matrix ... 详细信息

1997 IEEE International conference on Acoustics, Speech, and signal processing (ICASSP 97)
作者: Nadaud, S Trouilhet, JF Lab d'Acoustique de Metrologie et d'Instrumentation Toulouse France
This article presents two modelling methods using wavelet networks. Both methods are intended to be used for an acoustic pulse signal classifier. We present a few results obtained with signals coming from a recording ... 详细信息

conference on wavelet applications in signal and image processing Vii
作者: He, Y Krim, H N Carolina State Univ Dept Elect & Comp Engn Ctr Adv Comp & Commun Raleigh NC 27695 USA
In this paper, we propose a new algorithm for extracting a non smooth shape from its noisy observation. The key ideal is to project the noisy shape onto a set of orthogonal subspaces at different resolutions, and cons... 详细信息

4th conference on wavelet applications in signal and image processing
作者: Yaroslavsky, LP TEL AVIV UNIV FAC ENGN DEPT INTERDISCIPLINARY STUDIES IL-69978 TEL AVIV ISRAEL
On the base of local criteria of processing quality, a class of local adaptive linear filters for image restoration and enhancement is introduced. The filters work in a running window in the domain of DFT of DCT and h... 详细信息

wavelets - applications in signal and image processing X conference
作者: Kutyniok, G Univ Gesamthsch Paderborn Dept Math D-33095 Paderborn Germany
Density conditions have turned out to be a powerful tool for deriving necessary conditions for weighted wavelet systems to possess an upper or lower frame bound. In this paper we study different definitions of density... 详细信息

IEEE International conference on image processing (ICIP 2000)
作者: Takano, S Niijima, K Kyushu Univ Dept Informat Kasuga Fukuoka 8168580 Japan
This paper proposes a method for extracting subimages from a huge reference image by using lifting wavelet transforms that map integers to integers. Our integer-type lifting wavelet transform contains controllable fre... 详细信息

IEEE International conference on Acoustics, Speech, and signal processing
作者: Frajka, T Zeger, K Dept. of Elec. and Comp. Engineering University of California San Diego La Jolla CA 92093-0407 United States
We present a packetization method for robust image transmission over packet erasure channels. The packets are formed in such a way that the image information is spread over different frequency bands and spatial locati... 详细信息

conference on wavelet applications in signal and image processing ii
作者: WANG, WL YAN, YB JIN, GF WU, MX TSING HUA UNIV DEPT PRECIS INSTRUMENTS100084 BEIJINGPEOPLES R CHINA
Textured image is considered as the repetition of some primitives with a certain rule of displacement, thus every region in the image has different periodic structure. The segmentation is realized by its self-imaging ... 详细信息

conference on wavelet applications in signal and image processing ViiI
作者: Khalil, MI Bayoumi, MM Queens Univ Dept Elect & Comp Engn Kingston ON K7L 3N6 Canada
Dyadic wavelet transform has been used to derive affine invariant functions. The invariant functions are based on the dyadic wavelet transform of the object boundary. Two invariant functions have been calculated using... 详细信息

IEEE International conference on image processing (ICIP 2000)
作者: Romberg, J Choi, H Baraniuk, R Kingsbury, N Rice Univ Dept Elect & Comp Engn Houston TX 77005 USA
Multiresolution signal and image models such as the hidden Markov tree (HMT) aim to capture the statistical structures of smooth and singular (textured and edgy) regions. Unfortunately, models based on the orthogonal ... 详细信息
