Infants’ visual tracking of continuous circular motion under conditions of occlusion and non-occlusion
We investigated horizontal and vertical gaze in 9-month-old infants while tracking a fully visible or partly occluded target moving in a circular trajectory. The possibilities for using a corneal-reflection technique (ASL) in such tasks were explored. Data show that horizontal tracking is adult-like at this age over frequencies investigated (0.05–0.4 Hz), vertical tracking is adult-like over th...
متن کاملPredictive visual tracking
Due to delays in image acquisition and processing, prediction is a critical factor for successful visual tracking of moving objects (both for humans and for vision machines). This paper explores some alternative techniques for predicting object motion for the purpose of tracking with an active camera system. In particular, one of our goals is to develop a system that will track an object underg...
متن کاملOcclusion Reasoning for Multiple Object Visual Tracking
Occlusion reasoning for visual object tracking in uncontrolled environments is a challenging problem. It becomes significantly more difficult when dense groups of indistinguishable objects are present in the scene that cause frequent inter-object interactions and occlusions. We present several practical solutions that tackle the inter-object occlusions for video surveillance applications. In pa...
متن کاملSex differences during visual scanning of occlusion events in infants.
A growing number of sex differences in infancy have been reported. One task on which they have been observed reliably is the event-mapping task. In event mapping, infants view an occlusion event involving 1 or 2 objects, the occluder is removed, and then infants see 1 object. Typically, boys are more likely than girls to detect an inconsistency between a 2-object occlusion event and a 1-object ...
متن کاملPredictive tracking over occlusions by 4-month-old infants.
Two experiments investigated how 16-20-week-old infants visually tracked an object that oscillated on a horizontal trajectory with a centrally placed occluder. To determine the principles underlying infants' tendency to shift gaze to the exiting side before the object arrives, occluder width, oscillation frequency, and motion amplitude were manipulated resulting in occlusion durations between 0...
