For many tasks, we wish to record or recover thedescription of a remote environment so that it can be inspected by aperson. This is the problem we address in this paper. Rather thanrecovering a geometric description of an environment, as manyrobotics systems attempt to do, we seek to recover a model of anenvironment in terms of its appearance from a set of carefullyselected viewpoints. Our hope is that this type of model isboth more accessible to humans for many realistic tasks, and also morereadily achieved with automated systems. These viewpoints arelocations in the environment associated with views containing maximalvisual interest. This approach to environment representation isanalogous to image compression. Our goal is to obtain a set ofrepresentative views resembling those that would be selected by ahuman observer given the same task. Our computational procedure isinspired by models of human visual attention appearing in theliterature on human psychophysics. We make use of the underlyingedge structure of a scene, as it is largely unaffected by variationsin illumination. Our implementation uses a mobile robot to traversethe environment, and then builds an image-based virtualrepresentation of the environment, only keeping the views whoseresponses were highest. We demonstrate the effectiveness of ourattention operator on both single images, and in viewpoint selectionwithin an unknown environment.
