Item ShortStraw: A Simple and Effective Corner Finder for Polylines(The Eurographics Association, 2008) Wolin, Aaron; Eoff, Brian; Hammond, Tracy; Christine Alvarado and Marie-Paule CaniIn this paper we introduce ShortStraw, a simple and highly accurate polyline corner finder. ShortStraw uses a bottom-up approach to find corners by: (1) resampling the points of the stroke, (2) calculating the straw distance between the endpoints of a window around each resampled point, and (3) taking the points with the minimum straw distance to be corners. Using an all-or-nothing accuracy measure, ShortStraw achieves an accuracy more than twice that of the current best benchmark.
