A parallel method for locating and representing 2D contours

Research output: Contribution to journalArticle

Abstract

A parallel procedure for locating and representing 2D contours is discussed. At first, circular templates are used to determine the edge pixels and the dominant points with high local curvatures. Then arcs are acquired from the edge pixels and the dominant points. The arcs are used to examine the validity of the dominant points and to represent the contours of surfaces. The method is mainly based on template-matching procedures and a modified Hough transform. © 1992.
