Self-Supervised Scene De-Occlusion [PDF]
Computer Vision and Pattern Recognition, 2020 Natural scene understanding is a challenging task, particularly when encountering images of multiple objects that are partially occluded. This obstacle is given rise by varying object ordering and positioning.

Reversible middle cerebral artery occlusion without craniectomy in rats.
Stroke, 1989 To develop a simple, relatively noninvasive small-animal model of reversible regional cerebral ischemia, we tested various methods of inducing infarction in the territory of the right middle cerebral artery (MCA) by extracranial vascular occlusion in ...

Iterative Residual Refinement for Joint Optical Flow and Occlusion Estimation [PDF]
Computer Vision and Pattern Recognition, 2019 Deep learning approaches to optical flow estimation have seen rapid progress over the recent years. One common trait of many networks is that they refine an initial flow estimate either through multiple stages or across the levels of a coarse-to-fine ...

Occlusion Robust Face Recognition Based on Mask Learning With Pairwise Differential Siamese Network [PDF]
IEEE International Conference on Computer Vision, 2019 Deep Convolutional Neural Networks (CNNs) have been pushing the frontier of face recognition over past years. However, existing CNN models are far less accurate when handling partially occluded faces.

Occlusion Aware Unsupervised Learning of Optical Flow [PDF]
2018 IEEE/CVF Conference on Computer Vision and Pattern Recognition, 2017 It has been recently shown that a convolutional neural network can learn optical flow estimation with unsupervised learning. However, the performance of the unsupervised methods still has a relatively large gap compared to its supervised counterpart ...

Antimicrobial Effect of Titanium Hydroxyapatite in Denture Base Resin
Applied Sciences, 2018 In the current study, we investigated the antimicrobial effect of titanium hydroxyapatite (TiHA), a photo-oxidizing organic material, in denture base resin on single-species biofilms formed by laboratory bacteria and on multispecies biofilms formed by ...
