International conference on signal processing and Communications
作者: Shivamurti, M. Narasimhan, S. v. Natl Aerosp Labs CSIR Digital Signal Proc & Syst Grp Aerosp Elect & Syst Div Bangalore 560017 Karnataka India
A new simple and efficient analytic wavelet transform based on Discrete Cosine Harmonic wavelet Transform DCHWT (ADCHWT) has been proposed and is applied for signal and image denoising. The analytic DCHWT has been rea... 详细信息

conference on wavelet applications in signal and image processing v
作者: Klappenecker, A May, FU Nuckel, A Univ. Karlsruhe (Germany)
In this paper we give a brief introduction to filter banks over commutative rings. In contrast to filter banks over the real numbers, we employ finite ring arithmetic to control the number of bits in the signal repres... 详细信息

conference on wavelet applications in signal and image processing v
作者: Nowak, R Baraniuk, R Michigan State Univ. (United States) Rice Univ. (United States)
Many imaging systems rely on photon detection as the basis of image formation. One of the major sources of error in these systems is Poisson noise due to the quantum nature of the photon detection process. Unlike addi... 详细信息

4th IEEE International conference on signal and image processing (ICSIP)
作者: Yang, Jianbin Zhang, Enlin Wang, Cong Hohai Univ Dept Math Coll Sci Nanjing Jiangsu Peoples R China Xidian Univ Sch Electromech Engn Xian Shaanxi Peoples R China
image segmentation aims at partitioning an image into its constituent parts, which plays a crucial role in practical applications. In this paper, we present a wavelet frame-based model for color images segmentation, w... 详细信息

SPIE conference on wavelet applications v
作者: Siddiqui, KJ SUNY Coll Fredonia Dept Math & Comp Sci Fredonia NY 14063 USA
Modern image and signal processing methods strive to maximize signal to noise ratios, even in the presence of severe noise. Frequently,real world data is degraded by under sampling of intrinsic periodicities, or by sa... 详细信息

wavelets - applications in signal and image processing X conference
作者: Aston, J Turkheimer, F Cunningham, v Gunn, R US Bur Census Div Stat Res Washington DC 20233 USA
Typical neuroimaging studies place great emphasis on not only the estimation but also the standard error estimates of underlying parameters derived from a temporal model. This is principally done to facilitate the use... 详细信息

DIGITAL signal processing 2014年 33卷 148-155页
作者: Nezhadarya, Ehsan Ward, Rabab K. Univ British Columbia Dept Elect & Comp Engn Vancouver BC V5Z 1M9 Canada
A transform that estimates the first and higher-order derivatives of images at multiple scales is proposed. The proposed transform, called Multi-Scale Derivative Transform (MSDT), is specially designed for image water... 详细信息
