Content Based Image Retrieval Model in an Object Oriented Database

In this paper, we present an image retrieval system based on the content. The content of images include both low level features such as colors, textures, and high level features such as spatial constraints and shapes of relevant regions. Based on object technology, the image features and behaviors are modeled and stored in a database. Images can be retrieved by examples (show me images similar to this image) or by selecting properties from pickers such as a sketched shape, a color histogram, a spatial constraint interface, a list of key words and a combination of these. The integration of high and low level features in the object-oriented database is an important property of our work.
