Thalamic pathways for active vision.
Active vision requires the integration of information coming from the retina with that generated internally within the brain, especially by saccadic eye movements. Just as visual information reaches cortex via the lateral geniculate nucleus of the thalamus, this internal information reaches the cerebral cortex through other higher-order nuclei of the thalamus. This review summarizes recent work...
متن کاملActive Vision for Wearables
In this paper we report on our ongoing research on wearable active vision, where we have iteratively prototyped a Wearable Visual Robot — a body mounted robot for which the main sensor is a camera. Two main areas have been studied: robot design and visual algorithms. In the design stage, we have analysed sensor placement through the computation of the field of view and body motion using a 3D mo...
متن کاملRepresentations for Active Vision
As the field of Computational Vision matures, more efforts are devoted to vision systems that are active and need to interact with their envi ronment in real time. A prerequisite for inte grating Vision and Action is the development of a set of representations of the visual system's space-time, where space includes the system itself. Thus we are faced with the problem of studying the nature o...
متن کاملFuzzy processing for active vision
Humans employ an active visual system to gather visual data from the surrounding environment. In addition to continually re-focusing the lens and adjusting the iris to control the exposure of light on to the retina, the eye constantly moves so that specific information can be focused on to the fovea – the part of the retina capable of defining fine detail. The target location when the eye moves...
