Research on the Static Response Mechanism of Event Cameras and Their Applications in Static Scenes
Event cameras are novel sensors that have gained significant importance in the field of dynamic vision since the first prototype in 2008. Unlike conventional frame-based cameras, event cameras exhibit independent and asynchronous responses at each pixel to changes in brightness. This unique …

Weathering of wood surfaces: characteristics, mechanisms, and prevention
Photodegradation of southern yellow pine, its mechanisms and means of prevention were studied. Changes in brightness and color were recognized when wood was exposed outdoors or to ultraviolet light. Scanning electron micrographs showed that most of the cell walls on irradiated transverse surface …

Active and passive microwave remote sensing: Validation and scaling over an agricultural region
Monitoring soil moisture is important over agricultural regions for improving the skill of regional crop yield, flood and drought forecasting, and for assisting producers in making effective land-management decisions. Soil moisture data are available from Earth Observation missions, which use …

Towards image registration of dynamic contrast enhanced MRI using deep learning
… enhanced (DCE)-MRI is a quantitative imaging technique used to monitor microvascular perfusion. It involves rapidly acquiring multiple T1-weighted images over a few minutes whilst injecting a contrast agent, which causes a rapid increase in image intensity. Each type of tissue exhibits …

Microlensing of agn spectra
Quasars are considered to be the most luminous subclass among Active Galactic Nuclei. Although they appear to be distributed everywhere in the Universe, only a small fraction of them happen to be part of a fortuitous alignment with a galaxy or a galaxy cluster that lies along the line-of-sight, …
