Region Attention Networks for Pose and Occlusion Robust Facial Expression Recognition [PDF]

IEEE Transactions on Image Processing, 2019
Occlusion and pose variations, which can change facial appearance significantly, are two major obstacles for automatic Facial Expression Recognition (FER). Though automatic FER has made substantial progresses in the past few decades, occlusion-robust and

Occluded Prohibited Items Detection: An X-ray Security Inspection Benchmark and De-occlusion Attention Module [PDF]

ACM Multimedia, 2020
Security inspection often deals with a piece of baggage or suitcase where objects are heavily overlapped with each other, resulting in an unsatisfactory performance for prohibited items detection in X-ray images.

MaskFlownet: Asymmetric Feature Matching With Learnable Occlusion Mask [PDF]

Computer Vision and Pattern Recognition, 2020
Feature warping is a core technique in optical flow estimation; however, the ambiguity caused by occluded areas during warping is a major problem that remains unsolved.

Noncontrast Computed Tomography vs Computed Tomography Perfusion or Magnetic Resonance Imaging Selection in Late Presentation of Stroke With Large-Vessel Occlusion

JAMA Neurology, 2021
Key Points Question In patients with proximal anterior circulation occlusion stroke presenting in the extended window, are rates of favorable outcomes at 90 days comparable in the patients selected for thrombectomy with noncontrast computed tomography vs

Orthodontics and occlusion [PDF]

British Dental Journal, 2001
The discipline of orthodontics is directed towards alteration of the occlusion of the teeth and the relationships of the jaws. It is therefore somewhat surprising to find that there is little scientific evidence to support any of the concepts that suggest occlusal goals for orthodontic treatment.

Biomechanical behavior of three different types of internal tapered connections after cyclic and static loading tests: experimental in vitro

International Journal of Implant Dentistry, 2020
Background In the long-term success of a dental implant, the reliability and stability of the implant-abutment interface are important. Studies of maximum force of dental implants with different loading values have been used.

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.
