Semantic Content Based Image Retrieval Using Object-Process Diagrams

Abstract. The increase in accessability to on-line visual data has promoted the interest in browsing and retrieval of images from Image Databases. Current approaches assume either a text based key-word oriented approach or a visual feature based approach. The keyword approach usually provides neither layout information nor object relevence and signi cance in the scene. The visual feature based approach relies on low level features such as color, texture and orientation as image descriptors. These are non-intuitive and unnatural for human observers. This paper presents a new approach to image retrieval in which image content, based on the "visual scene", is the basis for both retrieval and user interface. We propose to model image content using Object-Process Diagrams. Our hierarchical approach incorporates both the low-level image features and textual key sentencess as descriptors of the image. These descriptions involve the objects in the scene and their inter- and intra-rel...
