Detection of linear features using a localized Radon transform
Abbie L. Warrick, Pamela A. Delaney · 2002
The Radon transform accentuates linear features and has been applied to detection and enhancement problems in images with linear features. However, several difficulties occur when the Radon transform is applied to images which have features with some curvature or features which do not cover the entire extent of the image. A localized Radon transform was established in Copeland et al. (1995) which successfully enhanced line segments and slightly curved features. In this paper an alternate derivation of the localized Radon transform to that of Copeland et al. is provided. Several properties not considered in in that paper are derived and a detection scheme for line segments is developed.
