SYSTEM AND METHOD FOR RECOGNISING SHAPE OF HAND-WRITTEN OBJECTS Russian patent published in 2009 - IPC G06K9/00 G06T7/00 

FIELD: information technologies.

SUBSTANCE: invention allows recognising the shape of hand-written objects irrespective of the entry order of marks and/or the number of marks required for forming any specified shape. Shape recognising unit can recognise the picture such as a diagram or a graph on the hand-written entry with inks by recognising closed containers and/or open connectors on the picture. Closed containers can represent any number of recognised shapes, including circles, ellipses, triangles, quadrangles, pentagons, hexagons, etc. Open connection links can represent any type of connection link, including lines, curves, arrows, etc. Polylines can be used for approximating the frame of the connection link in order to process the continued parts of marks, which are overlapped with fusion of marks and overlapped without fusion of marks of the frame.

EFFECT: by using this invention, user can freely draw diagrams and flow charts of algorithms without any restrictions imposed on hand-written entry.
