Enhancing robustness in asynchronous feature tracking for event cameras through fusing frame steams
Complex & Intelligent SystemsEvent cameras produce asynchronous discrete outputs due to the independent response of camera pixels to changes in brightness. The asynchronous and discrete nature of event data facilitate the tracking of prolonged feature trajectories. Nonetheless, this

Visualizing Three-Dimensional Ocean Eddies in Web Browsers
IEEE Access, 2019 Despite the importance of mesoscale eddies, and other three-dimensional features discernable in numerical simulations of ocean circulations, to the understanding of oceanic heat transport and climate change, there are few dedicated three-dimensional ...

Feature Tracking on the Unit Sphere [PDF]
Monthly Weather Review, 1995 Techniques used in a previous study of the objective identification\ud and tracking of meteorological features in model data are extended\ud to the unit sphere. An alternative feature detection scheme is described\ud based on cubic interpolation for the sphere and local maximization.\ud The extension of the tracking technique, used in the previous ...

Natural Killer Cells in Paediatric Soft Tissue Sarcomas: A Systematic Review
Pediatric Blood &Cancer, EarlyView.ABSTRACT Paediatric soft tissue sarcomas (pSTS) are a rare and heterogeneous group of malignant tumours arising in tissues of mesenchymal origin. The role of natural killer (NK) cells in pSTS remains poorly understood, with evidence fragmented across small preclinical studies and early‐phase clinical trials.

Hierarchical Feature-Aware Tracking
CoRR, 2019 In this paper, we propose a hierarchical feature-aware tracking framework for efficient visual tracking. Recent years, ensembled trackers which combine multiple component trackers have achieved impressive performance. In ensembled trackers, the decision of results is usually a post-event process, i.e., tracking result for each tracker is first obtained

Determining Parental Factors for Clinical Trial Attrition in Pediatric Acute Lymphoblastic Leukemia
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background/Objectives Despite high enrollment rates on Children's Oncology Group (COG) protocols, attrition after initial consent is challenging, introducing bias and prolonging trial completion. While adult oncology literature has identified predictors of withdrawal, little is known about caregiver decision‐making for child participation in ...
