A Corner-Finding Algorithm for Chain-Coded Curves
March 1977 (vol. 26 no. 3)
pp. 297-303
H. Freeman, Department of Electrical and Systems Engineering, Rensselaer Polytechnic Institute
A method for detecting sharp "corners" in a chain-coded plane curve is described. A measure for the prominence ("cornerity") of a corner is introduced. The effectiveness of the method is illustrated by means of a number of examples.
Index Terms:
Corner detection, image processing, incremental curvature, line-drawing processing.
