Summary:
In this paper, the author presents a framework for simultaneous grouping and recognition of shapes and symbols in free-form ink diagram. This paper has also adopted the graph method to recognize shapes. One advantage of this method is it does not require the order how user draw the strokes. For every symbol, a graph is build and then separated into smaller sub graph. The recognition is done between each sub graph.
Discussion:
A matching between whole graph is hard, however, if this matching could be applied to smaller sub graph, it is much easier. That is really the smartness of this paper.
Why didn't you guys to subgraph isomorphism in the final project?
