conference on wavelet applications in signal and image processing V
作者: He, WJ Lai, MJ Univ. of Georgia (United States)
We give many examples of bivariate nonseparable compactly supported orthonormal wavelets which are supported over [0,3]x[0,3]. The Holder continuity properties of these wavelets are studied.

conference on wavelet applications in signal and image processing VII
作者: Choi, H Baraniuk, R Rice Univ Dept Elect & Comp Engn Houston TX 77005 USA
We discover a new relationship between two seemingly different image modeling methodologies;the Besov space theory and the wavelet-domain statistical image models. Besov spaces characterize the set of real-world image... 详细信息

14th International conference on Digital signal processing (DSP 2002)
作者: Papakostas, GA Karras, DA Mertzios, BG Democritus Univ Thrace Dept Electr & Comp Emg GR-67100 Xanthi Greece
In this paper, we present a new method of image coding using two popular imaging tools, Zernike moments and wavelets. The main idea is that we can produce appropriate image descriptors by involving an appropriate numb... 详细信息

IEEE International conference on image processing (ICIP 2007)
作者: He, Zhihai Univ Missouri Dept Elect & Comp Engn Columbia MO 65203 USA
In this work, we introduce a nonlinear geometric transform, called peak transform, for efficient image representation and coding. Coupled with wavelet transform and subband decomposition, the peak transform is able to... 详细信息

IEEE International conference on image processing (ICIP 2000)
作者: Berkner, K Gormish, MJ Schwartz, EL Boliek, M Ricoh Silicon Valley Inc Menlo Park CA 94025 USA
The problem of image enhancement arises in many applications such as scanners, copiers and digital cameras. Enhancement often includes a denoising and a deblurring or sharpening step. Similar to image compression, sta... 详细信息

conference on wavelet applications in signal and image processing V
作者: Vassiliou, A Wickerhauser, MV Amoco EPTG (United States) Washington Univ. (United States)
wavelet transform coding image compression is applied to two raw seismic data sets. The parameters of filter length, depth of decomposition, and quantization method are varied through 36 parameter settings and the rat... 详细信息

IEEE International conference on Acoustics, Speech, and signal processing
作者: Fekri, F McLaughlin, SW Mersereau, RM Schafer, RW Georgia Inst Technol Ctr Signal & Image Proc Atlanta GA 30332 USA
The primary goal of this paper is to give examples of the recently developed (finite-field) wavelet coding method by studying the encoder and decoder for some half-rate codes. We propose a decoding methodology based o... 详细信息
