Abstract
The problem confronted in the content-based image retrieval research is the semantic gap between the low-level feature representing and high-level semantics in the images. This paper describes a way to bridge such gap: by learning the similar images given from the user, the system extracts the similar region pairs and classifies those similar region pairs either as object or non-object semantics, and either as object-relation or non-object-relation semantics automatically, which are obtained from comparing the distances and spatial relationships in the similar region pairs by themselves. The system also extracts interesting parts of the features from the similar region pair and then adjusts each interesting feature and region pair weight dynamically. Using those objects and object-relation semantics as well as the dynamic weights adjustment from the similar images, the semantics of those similar images can be mined and used for searching the similar images. The experiments show that the proposed system can retrieve the similar images well and efficient.
