Abstract

We study three transformation-invariant shape descriptors and evaluate their relative strengths in the context of content-based retrieval of graphical sketches. We show that the use of a combination of different shape representations may lead to a significant improvement of retrieval performance and identify an optimal combination that proves robust across different data sets and queries.
