FD: A feature difference based image clutter metric for targeting performance

open access: yes, 2012
Previous image clutter metrics were proposed based on the sensitivity of human visual perception to one feature of image. In this paper, a novel feature difference based image clutter metric is proposed by fully considering low-level image features, such

Apathy in Parkinson's Disease: Distinguishing Overlapping Symptoms Via Network Analysis

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Anxiety, fatigue, and excessive daytime sleepiness (EDS) frequently co‐occur in Parkinson's disease (PD) and can influence the clinical determination of apathy. Objective To distinguish patient‐reported apathy from other non‐motor symptoms.

The effects of visual clutter on driving performance

open access: yes, 2009
Driving a motor vehicle is a complex activity, and errors in performing the driving task can result in crashes which cause property damage, injuries, and sometimes death.

Optical Detuning Strategies for Shielded Loop Resonators

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To compare detuning performance and evaluate power requirements of optical detuning methods and to demonstrate feasibility of an optically‐detuned 4‐channel receive array. Methods Four optical detuning methods were compared in simulations, bench tests, and phantom measurements at 3T against conventional galvanic detuning.

Where were all the trees? Computer vision meets landscape history to unlock the potential of historical Ordnance Survey maps

open access: yesPeople and Nature, EarlyView.
Abstract The first edition of the Ordnance Survey's 1:2500 County Series is marked with treed areas, such as woodlands and orchards, and, remarkably, freestanding trees. Consequently, it is an unparalleled source of information on the distribution of trees across Britain in the mid‐late nineteenth century, when the maps were first surveyed. In order to

DSIM: A DisSIMilarity-based image clutter metric for targeting performance

open access: yes, 2013
Previous image clutter metrics were proposed on the thought that clutter was just a perceptual effect, while we identify clutter as both perceptual and cognitive effects.

The influence of acoustic characteristics and anthropogenic noise on restorative perceptions of natural soundscapes

open access: yesPeople and Nature, EarlyView.
Abstract Natural soundscapes are an important cultural ecosystem service that can promote mental health and well‐being. However, the role of specific acoustic characteristics in delivering these benefits and the constraining effects of anthropogenic noise are currently unclear.

Modeling rainfall drop size distribution moments using an S‐band polarimetric radar in complex terrain

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Using S‐band dual‐polarization radar and disdrometers during PRECIP 2022 in Taiwan, we analyze a Mei‐Yu frontal event with widespread stratiform rain and embedded convection. Multiple disdrometers are used to create a novel drop size distribution model for S‐band radars resolving both the drizzle and precipitation modes. The model reveals both inferred

Enhancing severe convection forecasts with microwave radiance assimilation in limited‐area models

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Microwave satellite radiances remain largely underexploited in convection‐permitting limited‐area models. We assess the assimilation of humidity‐sensitive radiances from the MHS instrument in the operational ICON‐2I model, improving the precipitation forecast of a severe convective event over the Marche region, Italy, substantially by correcting ...
