Wave Structure Detection through Two-Dimensional Filtering.

Abstract

This report contains an analysis of the potential of using a noncoherent two-dimensional filter technique to extract a ridge-like signal from a two-dimensional surface. The two-dimensional surface consists of the signal plus white Gaussian noise. It is demonstrated that the technique shows promise both in visual ridge detection and in automatic energy ratio detection. It is suggested that a more elegant form of the filter used here (complex coefficient) be used to further enhance the ridge-like signal structure. (Author)
