Abstract

Sketch matching algorithms are commonly used for indexing and retrieval of documents based on printed or hand-drawn sketches.One could use a hand-held computer to do sketch-based queries to a database containing hand-drawn and printed sketches.We present an on-line hand-drawn sketch matching algorithm based on a line-based representation of sketches.A distance measure is defined for comparing two sketches based on this representation. The algorithm is computationally efficient and achieves a recall rate of 88.44% at the same precision, when tested on a database of 150 sketches collected from 5 users.
