A Heuristic Method of Optimal Generalized Hypercube Encoding for Pictorial Databases.

Abstract

Similarity retrieval from a large pictorial database can be much more efficient by encoding the original database into certain convenient formats. Generalized hypercube (GH) encoding is one such technique. To optimize GH coding, a heuristic approach has been formulated. Two optimization problems have been considered here: First, given the handle length m, find the optimal GH sub m encoding. Second, given the threshold density, find the optimal GH encoding such that each generated hypercube has a density no less than a threshold density. (Author)
