Abstract

A new class of algorithms, based on triangle inequality, has recently been proposed for use in content-based image retrieval. These algorithms rely on comparing a set of key images to the database images, and storing the computed distance distances. Query images are later compared to the keys, and the triangle inequality is used to speedily compute lower bounds on the distance from the query to each database image. This paper addresses the question of increasing performance of this algorithm, by the addition of a data structure known as the Triangle Trie.
