Martin Guay



I am a research scientist in visual computing working on markerless motion capture using deep learning. I am excited about combining graphics with vision: on the one hand, to create large datasets for machine learning, and on the other, for unlocking new capabilities in Augmented Reality (AR). For example, putting watertight clothes onto people in AR, or having virutal characters interact with the real world in a realistic way.

Intresting note: I spent last year working on a smart 3D virtual assistant (that you can talk with and interact with).

My original background is in graphics and games. After my bachelor's, I spent two years working on different video games, which led me to doing a master's on real time fluid simulation and a ph.d. on character animation.

Projects and Publications



Pose and shape estimation from images and video


Marker-less motion capture for animation and virtual production.

Cloth
Putting together state-of-the-art body tracking from a single camera using deep learning,
leveraging 3D motion capture and lot's of 3d models.

Capturing Animal Motion from Video
lion
There is really no available dataset of animal images labelled with 3D position information.
This is learned from synthetic data, using computer generated imagery.
