Landmark-based approaches to robot navigation require an \interest operator" to estimate the utility of a particular image region as an eeective representative for a scene. This paper presents a color interest operator consisting of a weighted combination of heuris-tic scores. The operator selects those image regions (landmarks) likely to be found again, even under a diierent viewing geometry and/or diierent illumination conditions. These salient regions yield a robust representation for… CONTINUE READING
