Content-based image retrieval systems: A survey

Abstract

In many areas of commerce, government, academia, and hospitals, large collections of digital im-
\nages are being created. Many of these collections are the product of digitizing existing collections of
\nanalogue photographs, diagrams, drawings, paintings, and prints. Usually, the only way of search-
\ning these collections was by keyword indexing, or simply by browsing. Digital images databases
\nhowever, open the way to content-based searching. In this paper we survey some technical aspects
\nof current content-based image retrieval systems.
