Pupil Size Estimation Based on Spatially Weighted Corneal Flux Density
IEEE Photonics Journal, 2019 The pupil size is an important parameter in different studies on vision and ophthalmology. A pupil size estimation model is constantly needed when actual measurements are unavailable.

Visual marking and visual change.
Journal of Experimental Psychology: Human Perception and Performance, 2002 Five experiments investigated the types of changes that disrupt the preview effect--the benefit gained in difficult search tasks from presenting some distractors earlier in time. A shape change with or without an overall luminance change at the location of an old item was found to disrupt the preview effect, whereas an equivalent luminance change alone

Personalized Visualization Recommendation [PDF]
arXiv, 2021 Visualization recommendation work has focused solely on scoring visualizations based on the underlying dataset and not the actual user and their past visualization feedback. These systems recommend the same visualizations for every user, despite that the underlying user interests, intent, and visualization preferences are likely to be fundamentally ...

Visual Servoing and Visual Tracking [PDF]
, 2008 This chapter introduces visual servo control, using computer vision data in the servo loop to control the motion of a robot. We first describe the basic tech- niques that are by now well established in the field. We give a general overview of the formulation of the visual servo control problem, and describe the two archetypal visual servo control ...

Impact of Injection Rate on Flow Mixing during the Refining Stage in an Electric Arc Furnace
MetalsDuring the refining stage of electric arc furnace (EAF) operation, molten steel is stirred to facilitate gas/steel/slag reactions and the removal of impurities, which determines the quality of the steel.

Design Strategies Toward Plasmon-Enhanced 2-Dimensional Material Photodetectors
Advanced Devices & Instrumentation, 2023 Two-dimensional (2D) materials have become more advantageous compared with traditional semiconductor materials for fabrication of modern photodetectors operating at room temperature and possessing small volume and low power consumption. However, the weak

Current Biology, 2000 Visual search is the process of finding things that you are looking for in a world full of things that you are not looking for. Search tasks are ubiquitous. Many are so routine that we do not think of them as search tasks (e.g., Where is the space bar on the keyboard?). Others are more taxing (Where is the cat hiding?) and/or more important (Is there a
