abstract = {Similarity-based retrieval of visual shapes is performed
using a vector space technique originally developed for document
retrieval. In that technique, a document is represented by a vector in
which component is the frequency of occurence of a specific term (word
or phrase) in that document. Similarity between query and database
documents is measured by the normalized inner product of the vectors.
In the shape retrieval system, contours are partitioned into
perceptually significant segments that have a role analogous to words
in a document. Short sequences of segments are analogous to phrases.
Each shape is represented by a vector of the frequency of occurences of
each term (segments or segment sequences). Fast retrieval is achieved
by using a $B+$ tree and inverted lists. Additionally, a new similarity
measure is introduced and shown to result in improved performance over
the normalized inner product},
