Automated Histological Analysis System for Quantifying Microstructural Damage Accumulation to the Annulus Fibrosus
Ben Daya, Ibrahim; Noguchi, Mamiko; Callaghan, Jack P.; Wong, Alexander (Kitchener-Waterloo Vision and Imaging Society, 2016)In this paper, we proposed an automated histological analysis system for quantifying microstructural damage accumulation to the annulus fibrosus. This system takes in a digital histology image and uses Gaussian mixture ... -
Compensated Row-Column Ultrasound Imaging System Using Fisher Tippett Multilayered Conditional Random Field Model
Yeow, John; Ben Daya, Ibrahim; CHEN, ALBERT I-HSIANG; Shafiee, Mohammad Javad; Wong, Alexander (PLOS, 2015-12-11)3-D ultrasound imaging offers unique opportunities in the field of non destructive testing that cannot be easily found in A-mode and B-mode images. To acquire a 3-D ultrasound image without a mechanically moving transducer, ... -
Low-Cost Visual/Inertial Hybrid Motion Capture System for Wireless 3D Controllers
Wong, Alexander (University of Waterloo, 2007-05-10)It is my thesis that a cost-effective motion capture system for wireless 3D controllers can be developed through the use of low-cost inertial measurement devices and camera systems. Current optical motion capture systems ... -
Probabilistic complex phase representation objective function for multimodal image registration
Wong, Alexander (University of Waterloo, 2010-08-05)An interesting problem in computer vision is that of image registration, which plays an important role in many vision-based recognition and motion analysis applications. Of particular interest among data registration ... -
Scalable image segmentation via decoupled sub-graph compression
Medeiros, Rafael Sachett; Wong, Alexander; Scharcanski, Jacob (Elsevier, 2018-06-01)Dealing with large images is an on-going challenge in image segmentation, where many of the current methods run into computational and/or memory complexity issues. This work presents a novel decoupled sub-graph compression ...
