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 ... -
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-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 determinants of postural control and perception during physical and visual motion
(University of Waterloo, 2023-01-30)The control of balance and posture is a critical task of daily life to limit the risk of falls and potential injury. In order to be successful in the control of balance the central nervous system utilizes sensory feedback ... -
Visual Functions in Parkinson’s Disease
(University of Waterloo, 2018-06-19)Background: Freezing of gait (FOG) is considered to be a motor disorder symptom that affects some Parkinson Disease (PD) patients; however, it is hypothesized that sensory systems may also be involved in FOG. Purpose: ... -
Visual Functions in Post-Concussion Syndrome
(University of Waterloo, 2018-10-24)Purpose: Post-concussion syndrome (PCS) is a is a complex neurological disorder in which various concussion symptoms can last for weeks, months, or even years after sustaining the concussion. The PCS population has been ... -
Visual Inputs and Motor Outputs as Indivduals Walk Through Dynamically Changing Environments
(University of Waterloo, 2006-12-01)Walking around in dynamically changing environments require the integration of three of our sensory systems: visual, vestibular, and kinesethic. Vision is the only modality of these three sensory systems that provides ... -
