Building skeletal graphs for structural feature extraction on handwriting images
Hanhong Xue, Venu Govindaraju · 2002
Presents a method of building skeletal graphs for handwriting images, aiming at extraction of high-level structural features such as loops, turns, ends, and junctions. Block adjacency graphs are used as the base representation and transformed at locations where deformation occurs to obtain satisfactory skeletal graphs. Then the identification and ordering of structural features are considered based on skeletal graphs.
