Abstract Can our video understanding systems perceive objects when a heavy occlusion exists in scene? To answer this question, we collect large-scale dataset called OVIS for occluded instance segmentation, that is, to simultaneously detect, segment, and track instances scenes. consists of 296k high-quality masks from 25 semantic categories, where object occlusions usually occur. While human vis...

— FRUC (Frame Rate Up-Conversion) technique needs an effective frame interpolation algorithm using motion information between adjacent neighboring frames. In order to have good visual qualities in the interpolated frames, it is necessary to develop an effective detection and interpolation algorithms for occluded regions. For this aim, this paper proposes an effective occluded region detection a...

Purpose Transcatheter angiography is the gold standard for evaluating the condition and anatomy of the dural sinuses in patients with arteriovenous fistulas (AVFs); however, the patency and intraluminal condition of the dural sinuses can also be evaluated on magnetic resonance imaging (MRI). The purpose of this study was to evaluate the usefulness of MRI for the diagnosis of sinus occlusion. Ma...

The completion of partly occluded objects appears instantaneous and effortless, but empirically takes measurable time. The current study investigates how amount of occlusion affects the time course and mechanisms of visual completion. Experiment 1 used a primed-matching paradigm to determine completion times for objects occluded by various amounts. Experiments 2 and 3 used a dot-localization pa...

We present a framework that allows an observer to determine occluded portions of a structure by finding the maximum-likelihood estimate of those occluded portions consistent with visible image evidence and a consistency model. Doing this requires determining which portions of the structure are occluded in the first place. Since each process relies on the other, we determine a solution to both p...
