A Color Interest Operator for Landmark-Based Navigation

  title={A Color Interest Operator for Landmark-Based Navigation},
  author={Zachary Dodds and Gregory D. Hager},
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
