Sketch recognition
Encyclopedia
Sketch recognition is the automated recognition of hand-drawn diagram
s by a computer
. Research in sketch recognition lies at the crossroads of Artificial Intelligence
and Human Computer Interaction. Recognition algorithms usually are gesture
-based, appearance-based, geometry
-based, or a combination thereof.
Diagram
A diagram is a two-dimensional geometric symbolic representation of information according to some visualization technique. Sometimes, the technique uses a three-dimensional visualization which is then projected onto the two-dimensional surface...
