We first design a scheme of region-based image representation based on concept units, which are integrated with different types of feature spaces and with different region scales of image segmentation. The design of the concept units aims at describing similar characteristics at a certain perspective among relevant images. We present the details of our proposed approach based on a state-space model for interactive image retrieval, including likelihood and transition models, and we also describe some experiments that show the efficacy of our proposed model. This work demonstrates the feasibility of using a state-space model to estimate the user intuition in image retrieval.application/pdf1218131 bytesapplication/pdfen-USImage retrieval; Image segmentation; Learning systems; Image representation; Likelihood; Transition models; State space methodsjournal article10.1155/2007/835262-s2.0-34347338755http://ntur.lib.ntu.edu.tw/bitstream/246246/154592/1/24.pdf
