3D optical metrology by digital moiré: Pixel-wise calibration refinement, grid removal, and temporal phase unwrapping
(University of Waterloo, 2017-01-24)Fast, accurate three dimensional (3D) optical metrology has diverse applications in object and environment modelling. Structured-lighting techniques allow non-contacting 3D surface-shape measurement by projecting patterns ... -
Detection and Prediction of Freezing of Gait in Parkinson’s Disease using Wearable Sensors and Machine Learning
(University of Waterloo, 2021-10-12)Freezing of gait (FOG), is a brief episodic absence of forward body progression despite the intention to walk. Appearing mostly in mid-late stage Parkinson’s disease (PD), freezing manifests as a sudden loss of lower-limb ... -
Evaluation of Accelerometer-Based Walking-Turn Features for Fall-Risk Assessment in Older Adults
(University of Waterloo, 2017-05-17)Falls in older adult populations are a serious health concern, resulting in physical and psychological trauma in addition to increased pressure on healthcare systems. Faller classification and fall risk assessment in elderly ... -
Evaluation of Wearable Sensors as an Older Adult Fall Risk Assessment Tool
(University of Waterloo, 2016-07-19)Falls are common in the geriatric population, with approximately one third of older adults falling each year. Falls can result in lasting physical and psychological consequences and cost approximately $20 billion per year ... -
Fusion of Estimated Depth and RGB Features for Improved Grasp-Type Selection of Novel Objects
(University of Waterloo, 2022-09-01)Prostheses can alleviate some of the challenges faced by upper limb amputees in performing activities of daily living. However, electric-powered prosthetic hands have not seen much improvement over the past decade. Unintuitive ... -
Prediction and Detection of Freezing of Gait in Parkinson's Disease using Plantar Pressure Data
(University of Waterloo, 2021-01-26)Parkinson’s disease (PD) is a progressive neurodegenerative disorder affecting movement and is characterized by symptoms such as tremor, rigidity, and Freezing of Gait (FOG). FOG is a walking disturbance seen in more ... -
Real-time 3D surface-shape measurement using fringe projection and system-geometry constraints
(University of Waterloo, 2019-09-11)Optical three-dimensional (3D) surface-shape measurement has diverse applications in engineering, computer vision and medical science. Fringe projection profilometry (FPP), uses a camera-projector system to permit high-accuracy ... -
Use of Slip Prediction for Learning Grasp-Stability Policies in Robotic-Grasp Simulation
(University of Waterloo, 2023-07-04)The purpose of prosthetic hands is to restore a portion of dexterity lost through upper limb amputation. However, a key capability of human grasping that is missing from most currently available prosthetic hands is the ...
