Automatic infrasound signal detection using the Hough transform

Brown, David J; Whitaker, Rodney; Kennett, Brian; Tarlowski, Chris


The Hough transform is a mathematical device that allows the retrieval of parametric curve information from binary-pixelated data in the presence of noise. This slope-intercept transform maps each point in the image space S into a straight line in parameter space P and has the very useful property that all points in S that lie along the same straight-line map to the same number of straight lines in P with a common intersection point. Thus with a suitable counting procedure, the problem of...[Show more]
