Abstract
• Many existing image search engines arrange returned results in some default order on the screen, typically the relevance to a query (keyword), only. • Arguably, a more flexible and intuitive way would be to sort images into arbitrary structures such as grids, hierarchies, or spheres so that images that are visually or semantically alike are in proximal locations. • Arbitrary structures pose challenges as computing cross-similarities between images and structure coordinates will be a difficult task. • We instead exploit a recently developed machine learning technique: kernelized sorting. • We extend the technique so that some images can be pre-selected to guide the layouting process.
