Samples of Current Research Projects:

The following samples, mainly conference papers, give an overview of my current set of interdisciplinary research projects. In some cases conference posters are available, which give a convenient, snapshot overview. Most of these papers are described in greater detail in the journal articles and theses listed further down on this page.

PS PDF POST Wavelets & Statistics: Wavelets are widely used in signal and image processing, however relatively little is known about the statistical relationships which are obeyed.
PDF POST Colour Image Segmentation: New work in using Markov Random Fields for the segmentation of colour images. In particular, images with saturation or specular highlights, which confuse standard approaches to segmentation.
PS PDF POST SAR Interferometry Phase Unwrapping: Recent collaborative effort in approaching the problem of SAR interferometry using a statistical and hierarchical approach. In collaboration with the University of Montevideo, Uruguay.
PS PDF POST 3D Models From Stereo Video: A recent conference paper, looking at the problem of inferring 3D models from a stereo video sequence. This project looked at a novel way of attacking the problem incrementally. In collaboration with MDA Robotics (formerly Spar Aerospace), Brampton, Ontario.
PS PDF Clinical Optometry: A recent conference paper, seeking to address a problem in clinical optometry: how to judge the degree of redness or trauma in the cornea of the eye. In collaboration with the Centre for Contact Lens Research, University of Waterloo.
PS Hierarchical Estimation: A new approach to statistical hierarchical estimation, seeking to construct an overlapping tree. In collaboration with Bill Irving, MIT.
PS POST Remote Sensing: Estimating random fields and mapping problems for remote sensing. In collaboration with Dimitris Menemenlis, MIT (now at JPL).
PS PDF Data Fusion: A first look at satellite data fusion, in this case fusing the infrared information of the ocean surface collected by two different satellites. In collaboration with Oxford University / Rutherford Labs, United Kingdom.
PS PDF POST Hierarchical Estimation: Recent research work of my own, proposing a new class of hierarhical statistical trees, in which a tree is modified to have several roots, each of which is reponsible only for the subset of the given domain.
PS POST Dynamic Estimation: A modification of the hierarhical estimation method to allow dynamic estimation, here applied to oceanography. In collaboration with Terrence Ho, MIT.
PS PS Image Databases: A research problem to identify / recognize a given diamond from a database of millions of catalogued diamonds, for the purpose of preventing theft. In collaboration with GemPrint, Toronto.
PS POST Colour Tracking: A fast, simple, colour-based approach to tracking of objects, principally human heads, hands etc. In collaboration with Demetri Terzopoulos, University of Toronto.

Recent Journal Articles:

A subset of my journal publications follow. In general these files are relatively long; interested people may want to look at the samples, above, which tend to be smaller files and download more quickly.
