It is a kind of method which is from arc supposition to arc verification. Firstly extract the skeleton ofthe line-drawing image, then use the piecewise linear polygon to approximate the skeleton for more simplificationand reducing the quantum of data. After that, the local discrete curvature of every dominant point of the linearpolygon is calculated and the discrete curvature is used to assume some arcs exist locally. Finally the hypothesesare verified by mapping the hypothetical arcs back into the original image according to the arcs circle parameters.This proposed method has the advantages that it can deal with the conditions of rupture, intersection andoverlapping and it is robust and fast.
