Summary:
This paper has an interesting way to find the corners. Its actually based on primitive shape recognition. This algorithm has two steps- Stroke Approximation and Post processing.In Stroke Approximation, The algorithm tries to fit a stroke into some primitive. If it fails, it splits the stroke into two substrokes at point of highest curvature then feeds back to the algorithm. This paper proposes different recognition criteria for primitives (lines,arcs, curves, circles, ellipse, helix and spiral) which is similar to that discussed in PaleoSketch. The second step, post processing , involves merging corners and cleaning up false positives. This is very similar to mergeCF . Removing short lines, merging overlapping curves/arcs .
Discussion:
This paper forsees creation of a system which allows to configure it for any shape. LADDER framework achieves this. Its an interesting approach to find corners based on the primitives. Accuracy of 98% for polylines and 94% for arcs are impressive.

I agree that the accuracy rates are impressive.
