This paper presents a novel approach for searching images online using textual queries and presenting the resulting images based on both conceptual and visual similarities. Given a user-specified query, the algorithm first finds the related concepts through conceptual query expansion. Each concept, together with the original query, is then used to search for images using existing image search engines. All the images found under different concepts are presented on a 2D virtual canvas using a self-organizing map. Both conceptual and visual similarities among the images are used to determine the image locations so that images from the same or related concepts are grouped together and visually similar images are placed close to each other. When the user browses the search results, a subset of representative images is selected to compose an image collage. Once having identified images of interest within the collage, the user can find more images that are conceptually or visually similar through pan and zoom operations. Experiments on different image query examples demonstrate the effectiveness of the presented approach.
