متن کاملVisual attention and aging.
The present review of visual attentional processes and aging focuses on definitions of attention that emphasize some aspect of the control of information processing (selective attention) or the processing resources needed to drive these control processes (attentional capacity). Emphasis is placed on how increased adult age affects attentional mechanisms and how these age differences in attentio...
متن کاملLearning visual attention
Active vision is the skill that allows to control vision sensors and to filter visual signals in order to response to particular tasks and external stimuli in a fast and effective way. In biological and artificial systems it enables faster processing and reacting, providing meaningful information for subsequent activities such as navigation, manipulation, movements planning, interaction with th...
