Summary
SketchREAD (Sketch recognition ending for many domains) is a multi domain sketch recognition system capable of understanding freely drawn, messy, two dimensional diagrammatic sketches. The system provides a method for users to describe shapes which can be used to setup appropriate recognizers for the same. The system builds a Bayesian network and assigns probabilities for each interpretation given by the system.
Discussion
The system tries to model each shape by the set of rules and these rules can be used for recognizing objects later. It is much more intuitive than earlier methods as writing domain specific recognizer for each domain can be very tedious tasks. Rather the system lets the user to describe the shapes. An example showing the pattern used to describe a new shape:
