Robust Pedestrian Attribute Recognition Using Group Sparsity for Occlusion Videos [PDF]

arXiv, 2021
Occlusion processing is a key issue in pedestrian attribute recognition (PAR). Nevertheless, several existing video-based PAR methods have not yet considered occlusion handling in depth. In this paper, we formulate finding non-occluded frames as sparsity-based temporal attention of a crowded video. In this manner, a model is guided not to pay attention

OGMN: Occlusion-guided Multi-task Network for Object Detection in UAV Images [PDF]

, 2023
Occlusion between objects is one of the overlooked challenges for object detection in UAV images. Due to the variable altitude and angle of UAVs, occlusion in UAV images happens more frequently than that in natural scenes. Compared to occlusion in natural scene images, occlusion in UAV images happens with feature confusion problem and local aggregation

Wear of human teeth: a tribological perspective [PDF]

, 2005
The four main types of wear in teeth are attrition (enamel-on-enamel contact), abrasion (wear due to abrasive particles in food or toothpaste), abfraction (cracking in enamel and subsequent material loss), and erosion (chemical decomposition of the tooth)

Immediate flapless full‐arch rehabilitation of edentulous jaws on 4 or 6 implants according to the prosthetic‐driven planning and guided implant surgery: A retrospective study on clinical and radiographic outcomes up to 10 years of follow‐up

Clinical Implant Dentistry and Related Research, Volume 24, Issue 6, Page 831-844, December 2022., 2022
Abstract Objectives to retrospectively evaluate clinical and radiographic outcomes of immediate, flapless full‐arch prostheses, supported by 4/6 implants according to prosthetic‐driven planning and guided surgery. Materials and Methods The study involved 28 edentulous patients (20 female/8 males; average age 67.75 ± 8.627 years), 32 prostheses (17 all ...

GC-VTON: Predicting Globally Consistent and Occlusion Aware Local Flows with Neighborhood Integrity Preservation for Virtual Try-on [PDF]

arXiv, 2023
Flow based garment warping is an integral part of image-based virtual try-on networks. However, optimizing a single flow predicting network for simultaneous global boundary alignment and local texture preservation results in sub-optimal flow fields. Moreover, dense flows are inherently not suited to handle intricate conditions like garment occlusion by

RL-LABEL: A Deep Reinforcement Learning Approach Intended for AR Label Placement in Dynamic Scenarios [PDF]

, 2023
Labels are widely used in augmented reality (AR) to display digital information. Ensuring the readability of AR labels requires placing them occlusion-free while keeping visual linkings legible, especially when multiple labels exist in the scene. Although existing optimization-based methods, such as force-based methods, are effective in managing AR ...

Reference values and reliability of occlusal force distribution and occlusal time measured by the T-Scan system in adults with healthy dentition.

Journal of Prosthodontics
PURPOSE Reference values of occlusal characteristics are needed to interpret the data obtained using the T-Scan System. This study aimed to establish reference values for and to assess the reliability of, occlusal force distribution in the maximal ...

Suggested mesiodistal distance for multiple implant placement based on the natural tooth crown dimension with digital design

Clinical Implant Dentistry and Related Research, Volume 24, Issue 6, Page 801-808, December 2022., 2022
Abstract Purpose The purpose of this investigation was to identify a mesiodistal algorithm for multiple posterior implant placement based upon an ideal prosthetically restoration design. Methods One hundred one cases of posterior free‐end edentulous arches were selected for digital crown designs and measurements. Cone bean computed tomogram and digital

Tracking as A Whole: Multi-Target Tracking by Modeling Group Behavior with Sequential Detection [PDF]

, 2019
Video-based vehicle detection and tracking is one of the most important components for Intelligent Transportation Systems (ITS). When it comes to road junctions, the problem becomes even more difficult due to the occlusions and complex interactions among vehicles.
