Luttrell S P, July 1993, The application of mixture distributions to the detection of linear anomalies in cluttered images: a preliminary survey, DRA technical report (Malvern, UK), 4787
This memorandum outlines a new method of detecting anomalies (specifically, linear anomalies) in cluttered images. The novelty of the proposed technique lies in its use of so-called probability images (derived from mixture distributions) as an intermediate representation, to which standard Hough transform techniques are applied in order to locate linear features. The proposed technique is simple enough to be readily implemented in any standard image processing package.
