Sketch Retrieval Based on Topological Relations
基于空间关系的手绘草图检索

Sketching is a natural way for recording and conveying ideas.Along with more and more sketches created in ubiquitous computing,sketch retrieval has become a new issues.This paper presented an effective approach for sketch retrieval to improve the retrieval performance The topological relationship of sketch constitutes is used as the feature of similarity matching of the sketches,based on a user-independent sketch representation.Relevance feedback was also introduced to adjustment to refine the retrieval results by adjustment of feature point.Experiments prove the effective- ness and efficiency of the method.
