Abstract:

This paper describes a novel method of online composite shape recognition in terms of the relevance feedback technology to capture a user’s intentions incrementally, and a dynamic user modeling method to adapt to various users’ styles.First, the relevance feedback is adapted to refine the recognition results and reduce the ambiguity incrementally based on the establishment of a feature-based vector model of a user’s sketches.Secondly, a dynamic user modeling is introduced to model the user’s sketching habits based on recording and analyzing historical information incrementally.A model-based matching strategy is also employed in the method to recognize sketches dynamically.Experiments prove that the proposed method is both effective and efficient.
