P&auml;ivi Ovaska and Jussi Parkkinen,
A Pictorial Object-Oriented Database architecture for
	retrieving images by their content,
In <EM>The 10th Scandinavian Conference on Image Analysis</EM>,
Lappeenranta, Finland, pp. 59-64, June 1997.<P>An important decision in pictorial databases is to find
	the most appropriate data model and database architecture which takes
	into account the special features of pictorial information. These
	features include in the lower abstraction levels, complex operations
	and complex objects, and in the higher abstraction levels, the
	different semantical representations of pictorial information. We have
	developed in this work a new pictorial data model and database
	architecture named POOD. The model is based on object-oriented
	programming language approach with persistent objects. We have in this
	model persistent pictorial objects with an appropriate internal
	structure and image processing and analysis operations as methods of
	these objects. These persistent pictorial objects acts according to the
	object-oriented paradigm. The only difference compared to
	object-oriented programming language approach, is that the POOD object
	persists after the execution of the program. Objects are also under
	database control; they have transactions, concurrency control, and
	recovery facilities. We have made experiments by two pictorial database
	application areas: medical and geographical database. The POOD
	architecture and persistent object-oriented programming language
	approach proved to be an efficient basic environment for retrieving
	images by their content.
