This paper describes a novel approach for extracting a library of symbols from a large collection of line drawings. This symbol library is a compact and indexable representation of the line drawings. Such a representation is important for efficient symbol retrieval. The proposed approach first identifies the candidate patterns in all images, and then it clusters the similar ones together to create a set of clusters. A representative pattern is chosen from each cluster, and these representative patterns form a library of symbols. We have tested our approach on a database of line drawings, and it achieved high accuracy in capturing and representing the contents of the line drawings.
