An agent-based paradigm for free-hand sketch recognition

Natural interfaces for CAD applications based on sketching devices have been explored to some extent. Former approaches used techniques to perform the recognition process like invariant features extracted with image analysis techniques as neural networks, statistical learning or fuzzy logic. Currently, more flexible and robust techniques are being introduced, which consider other information as context data and other relationships. However, this kind of interfaces is still scarcely extended because they still lack scalability and reliability for interpreting user inputs. © Springer-Verlag 2009.
