Accessing images with multiple representations
Simone Santini, Amarnath Gupta · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2003
In this paper we present a formalism for query rewriting in the presence of data types with multiple representation, such as images. We show that the formalism is consistent and that it allows to derive rewriting rules, and we argue that the algebraic level at which it is express is the appropriate level for image access systems distributed over the internet, in which the internal details of the individual data repositories are not accessible from outside the local environment.
