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.
Corner detection, image processing, incremental curvature, line-drawing processing.
