Introduction
The Segzin Stahovich Davis system is meant to take sketch data and clean it up and recognize basic shapes within a drawing. There are several steps to this process. The first is vertex detection which requires filtering out noise to find vertexes on straight edge objects. The second is detecting curves and drawing/approximating them with bezier curves. Finally the figures are beautified and then basic object recognition.
Discussion
This paper gives a fair amount of description about the vertex and curve detection processes, however it does not give very many specifics on beautification or recognition or for that matter what sort of recognition applications this system would be used for. I can only assume it was an early paper that is further expounded upon later, or that most of the other concepts were explored sufficiently in the related work.
