Image Database Query Techniques: A Survey

Image databases attempt to allow users to effectively search through large sets of images. These images are typically captured intentionally by a human (eg. vaca- tion pictures) or automatically by cameras attached to sensors (eg. a security camera in an airport). As with all other searchable end-to-end database systems, image databases need the following facilities: storage, indexing, querying, and result display. In this survey, I will focus on the method by which image databases can be queried as well as all supporting technologies such as feature ex- traction, query matching, and ranking.
