Attention and active vision
Visual perception results from the interaction of incoming sensory signals and top down cognitive and motor signals. Here we focus on the representation of attended locations in parietal cortex and in earlier visual cortical areas. We review evidence that these spatial representations are modulated not only by selective attention but also by the intention to move the eyes. We describe recent ex...
متن کاملIssues in active vision : attention and
In this paper which is a summary of our talk, we stress a systems approach for research in active vision. We also argue that design and analysis of seeing agents should be accompanied by experiments, requiring implementations, i.e. a constructive approach. In particular, we discuss two issues that we have worked with: use and integration of multiple cues and attention.
متن کاملVisual Attention: The Active Vision Perspective
This chapter discusses the relationship between covert visual attention and overt movements of the eyes. One of the most frequently emphasised facts concerning visual attention is the ability to attend covertly to a location in the visual field without directing the eyes to that location. Based on this, the “mental spotlight” metaphor has been widely prevalent and has given rise to much experim...

متن کاملAttention and Visual Search: Active Robotic Vision Systems that Search
Visual attention is a multi-faceted phenomenon, playing different roles in different situations and for different processing mechanisms. Regardless, attention is a mechanism that optimizes the search processes inherent in vision. This perspective leads to a sound theoretical foundation for studies of attention in both machine and in the brain. The development of this foundation and the many way...
