Abstract

Currently, image retrieval systems are based on low-level features of color, texture and shape, not on the semantic descriptions that are common to humans, such as objects, people, and place. In order to narrow down the gap between the low level and semantic level, object-based content analysis, which segments the semantically meaningful objects of images, is an essential step. In this study, we propose a learning process in order to perform effective automatic off-line analysis on a multi-level segmented image stack. Meaningful objects are extracted given certain user search patterns and interest profiles. Color and/or shape information of the objects is stored in the hierarchical content representations of the images. This information is utilized by a hierarchical matching scheme to improve the retrieval speed in the subsequent searches.
