Viscous Liquid Animation with Spatially Adaptive Grids
(University of Waterloo, 2018-01-08)Viscous fluid behaviors are among the most complex yet familiar physical phenomena we encounter in everyday life. Much attention and investigation has been paid to the creation of visually realistic results, especially ... -
The Visibility Freeze-Tag Problem
(University of Waterloo, 2014-08-25)In the Freeze-Tag Problem, we are given a set of robots at points inside some metric space. Initially, all the robots are frozen except one. That robot can awaken (or “unfreeze”) another robot by moving to its position, ... -
Vision Augmented State Estimation with Fault Tolerance
(University of Waterloo, 2018-05-15)Obtaining accurate and reliable measurement data is really crucial for any vehicle system, especially if the system deals with maintaining safe operations of the vehicle. Conventional direct methods of obtaining such ... -
Vision-based Driver State Monitoring Using Deep Learning
(University of Waterloo, 2022-01-20)Road accidents cause thousands of injuries and losses of lives every year, ranking among the top lifetime odds of death causes. More than 90% of the traffic accidents are caused by human errors [1], including sight ... -
Vision-Based Observation Models for Lower Limb 3D Tracking with a Moving Platform
(University of Waterloo, 2011-08-23)Tracking and understanding human gait is an important step towards improving elderly mobility and safety. This thesis presents a vision-based tracking system that estimates the 3D pose of a wheeled walker user's lower ... -
Vision-based Self-Supervised Depth Perception and Motion Control for Mobile Robots
(University of Waterloo, 2022-07-18)The advances in robotics have enabled many different opportunities to deploy a mobile robot in various settings. However, many current mobile robots are equipped with a sensor suite with multiple types of sensors. This ... -
Vision-Inertial SLAM using Natural Features in Outdoor Environments
(University of Waterloo, 2006)Simultaneous Localization and Mapping (SLAM) is a recursive probabilistic inferencing process used for robot navigation when Global Positioning Systems (GPS) are unavailable. SLAM operates by building a map of the robot ... -
Visioning Diversity: Planning Vancouver's Multicultural Communities
(University of Waterloo, 2002)The roles and responsibilities of planners in managing culturally diverse cities are beginning to be articulated in the literature. "Visioning,"as planners have used it in recent years, has the potential to help realize ... -
Visioning in strategic planning, theory, practice and evaluation
(University of Waterloo, 1997) -
A visitor experience scale: historic sites and museums
(University of Waterloo, 2013-03-04)Since Pine and Gilmore (1999) proclaimed the arrival of the experience economy era, research on tourists’ experiences has become an area of growing interest among scholars and practitioners. Gaining knowledge of the ... -
Visitor Satisfaction at a Local Festival: An Importance-Performance Analysis of Oktoberfest
(University of Waterloo, 2014-03-31)The aim of this research was to provide a practical method for assessing visitor satisfaction at a local festival. It is crucial for festival management to monitor and evaluate visitor satisfaction in order to understand ... -
Visual and Text Coverage of Skin Cancer and Recreational Tanning in Popular North American Magazines from 2000 to 2012
(University of Waterloo, 2015-05-04)Background: Skin cancer is the most common type of cancer in North America and its incidence is increasing globally. It is a largely preventable disease through avoiding ultraviolet (UV) exposure and, when detected early, ... -
Visual Attention for Robotic Cognition: A Biologically Inspired Probabilistic Architecture
(University of Waterloo, 2010-06-18)The human being, the most magnificent autonomous entity in the universe, frequently takes the decision of `what to look at' in their day-to-day life without even realizing the complexities of the underlying process. When ... -
Visual attention to threat during stove-checking in people high in checking behaviour
(Elsevier ScienceDirect, 2022-10)Leading models of obsessive-compulsive disorder (OCD) state that hypervigilance to threat is a factor in compulsion persistence; however, previous research on attention deployment in OCD is mixed. The current study examines ... -
Visual Attention-based Small Screen Adaptation for H.264 Videos
(University of Waterloo, 2008-08-29)We develop a framework that uses visual attention analysis combined with temporal coherence to detect the attended region from a H.264 video bitstream, and display it on a small screen. A visual attention module based ... -
Visual Content Characterization Based on Encoding Rate-Distortion Analysis
(University of Waterloo, 2023-02-27)Visual content characterization is a fundamentally important but under exploited step in dataset construction, which is essential in solving many image processing and computer vision problems. In the era of machine learning, ... -
Visual correlates of balance and mobility in older adults: Can visual attention training improve performance?
(University of Waterloo, 2017-05-11)Falls among older adults is a serious problem facing our aging population. It is estimated that one in every three older adults aged 70+ fall every year; some of these experience multiple falls. Thirty five percent of ... -
Visual detection of lead(II) using a label-free DNA-based sensor and its immobilization within a monolithic hydrogel
(Royal Society of Chemistry, 2012-02-07)Lead is highly toxic and its detection has attracted a lot of research interests. In recent years, DNA has been used for Pb2+ recognition and many fluorescent sensors with low to sub-nM detection limits have been reported. ... -
