Title

Shape measures for content based image retrieval : a comparison

Source

Information processing and management. 33(1997) no.3, S.319-337

Abstract

Discusses effectiveness of several shape measures for content based similarity retrieval of images in multimedia and image database systems. Describes the different shape measures implemented. Given an image all these shape feature measures are computed automatically, and the feature vector can either be used for the retrieval purpose or can be stored in the database for future queries. Tests all thes shape features for image retrieval on a database of 500 trademark images. The average retrieval efficiency values computed over a set of 15 representative queries for all the methods is presented. The output of a sample shape similarity query using all the features is also shown
