When applying sparse representation techniques to images, the standard approach is to independently compute the representations for a set of overlapping image patches. This …
Guided-wave (GW) approaches have shown potential in various initial laboratory demonstrations as a solution to structural health monitoring (SHM) for damage prognosis …
The paper considers the task of recognizing environmental sounds for the understanding of a scene or context surrounding an audio sensor. A variety of features have been proposed …

We propose the audio inpainting framework that recovers portions of audio data distorted due to impairments such as impulsive noise, clipping, and packet loss. In this framework, the …
A seismic trace may be decomposed into a series of wavelets that match their time- frequency signature by using a matching pursuit algorithm, an iterative procedure of wavelet …

Interest in parameterized time-frequency analysis for non-stationary signal processing is increasing steadily. An important advantage of such analysis is to provide highly …
Many algorithms have been proposed to find sparse representations over redundant dictionaries or transforms. This paper gives an overview of these algorithms by classifying …
