| This is the final report summarizing research on the deployment of attention in visual search. In visual search, observers look for targets among distractor items. Models of search had assumed that items were sampled without replacement. items, rejected as distractors, would not be revisited during the search. Research reported here falsifies that hypothesis. Our data are consistent with sampling with replacement - no use of information about rejected distractors. The ... |

| Radical improvements in electronic sensor and processor capabilities in the past decade have destabilized basic definitions of imaging in general and three-dimensional imaging in particular. Conventionally, imaging refers to analog focal or holographic systems that integrate information acquisition and processing. Increasingly aggressive digital processing, however, diminishes the processing role in the sensor head. Particularly in sensor arrays, there is often no need for a well-formed 'image' in analog space. The ... |
