Color, Texture, and Symmetry for Focus of Attention in Images

A.H.F. Lau, M.D. Levine

It is well known that object symmetry is an important component in determining human focus of attention. Earlier, we have proposed a new method, based on symmetry in gray level images, for object isolation and segmentation in complex images and a real-time implementation has also been developed and tested. We have added to this analysis the two additional features of color and texture. Both region and edge analysis are used to compute a graph description of the important and salient objects in the scene. The user is able to interactively select a desired combination of perceptual variables to control which salient objects will be retrieved.
