The quest for the reliable direct detection of hydrocarbons from seismic data is probably as old as seismic data processing and interpretation itself. Over the years a few different methods have been ...

The multi-resolution decomposition of a function is similar to passing the signal through a bank of orthogonal filters. In signal-detection applications, a signal in the presence of noise is ...

Consider the situation when we have training data containing many time series having known group membership and testing data with unknown group membership. The goals are to find timescale features ...

ABSTRACT A new method to quantify changes in El Niño–Southern Oscillation (ENSO) variability is presented, using the overlap between probability distributions of the wavelet spectrum as measured by ...

Wavelets provide new capabilities for analyzing real-time signals. This introductory article provides an overview and presents the basic mechanisms involved in wavelets. In many signal processing ...
