WebAbstract—Active perception and foveal vision are the founda-tions of the human visual system. While foveal vision reduces the amount of information to process during a gaze ﬁxation, active perception will change the gaze direction to the most promising parts of the visual ﬁeld. We propose a methodology to emulate WebMost people have a high degree of reliance on their foveal vision (which is more connected to the conscious mind.) Peripheral vision, on the other hand, opens up to either side of you, above and even beneath you. Among other things, peripheral vision is useful for detecting sudden movement (which is more evident in the dark).

WebMore recently, active vision systems have been proposed for robotic platforms.
