Neural Substrates of Dynamic Object Occlusion [PDF]
Journal of Cognitive Neuroscience, 2007 Abstract In everyday environments, objects frequently go out of sight as they move and our view of them becomes obstructed by nearer objects, yet we perceive these objects as continuous and enduring entities. Here, we used functional magnetic resonance imaging with an attentive tracking paradigm to clarify the nature of perceptual and ...

Unsupervised Depth Completion Guided by Visual Inertial System and Confidence
Sensors, 2023 This paper solves the problem of depth completion learning from sparse depth maps and RGB images. Specifically, a real-time unsupervised depth completion method in dynamic scenes guided by visual inertial system and confidence is described.

Dynamic occlusion in the perception of rotation in depth [PDF]
Perception & Psychophysics, 1983 Occlusion of more distant texture elements by nearer elements can provide relative distance information in parallel projections of rotating objects, according to Braunstein, Andersen, and Riefer (1982). In that study, occlusion was present in static views in the form of contour interruptions or interposition.

Seeing Behind Dynamic Occlusions with Event Cameras
CoRR, 2023 Unwanted camera occlusions, such as debris, dust, rain-drops, and snow, can severely degrade the performance of computer-vision systems. Dynamic occlusions are particularly challenging because of the continuously changing pattern. Existing occlusion-removal methods currently use synthetic aperture imaging or image inpainting.
