Signal Representation using Wavelet Transform Modulus Maxima
نویسنده
چکیده
Ab8tmctWe examine the representation of signals by the Wavelet 'lhansform Modulus Maxima together with the alternating projection reconstruction algorithm proposed by Mallat. We show that the projection algorithm of Mallat is not minimum distance and not necessarily nonexpansive. Convergence is therefore not guaranteed. We describe an alternative projection operator which is minimum distance and nonexpansive and show that it is monotonically converging.

Local regularity analysis at glottal opening and closure instants in electroglottogram signal using wavelet transform modulus maxima
This paper deals with singularities characterisation and detection in Electroglottogram (EGG) signal using wavelet transform modulus maxima. These singularities correspond to glottal opening and closure instants (GOIs and GCIs), Wavelets with one and two vanishing moments are applied to EGG signal. We show that wavelet with one vanishing moment is sufficient to detect singularities of EGG signa...
متن کاملA deblocking technique for block-transform compressed image using wavelet transform modulus maxima
In this work, we introduce a deblocking algorithm for Joint Photographic Experts Group (JPEG) decoded images using the wavelet transform modulus maxima (WTMM) representation. Under the WTMM representation, we can characterize the blocking effect of a JPEG decoded image as: 1) small modulus maxima at block boundaries oversmooth regions; 2) noise or irregular structures near strong edges; and 3) ...
متن کاملPost-Processing for Low Bit-Rate Wavelet-Based Image Coding Using Multiscale Edge Characterization
In this paper, we propose a new postprocessing method for low bit-rate wavelet-based image coding which uses the technique of wavelet modulus maximum representation (WMMR). The edge degradation from wavelet-based coding is discussed under the overcomplete wavelet expansion, and interpreted as the distortion of wavelet modulus maxima, i.e., magnitude decays. Based on the empirical analysis and e...
متن کاملA scale-space approach with wavelets to singularity estimation
This paper is concerned with the problem of determining the typical features of a curve when it is observed with noise. It has been shown that one can characterize the Lipschitz singularities of a signal by following the propagation across scales of the modulus maxima of its continuous wavelet transform. A nonparametric approach, based on appropriate thresholding of the empirical wavelet coeffi...
متن کاملTime-Scale Dependencies for Image Compression
The definition of an atomic representation of the wavelet transform of a signal allows us to write the evolution law through scales for modulus maxima of the transform. Although this result is very general and useful for various fields of image processing, we focus on its application to signal and image compression. We propose a simple trick for taking advantage from the law without directly so...
