Graduate Students

Lyndon Chan
MASc ECE student at University of Toronto

Lyndon Chan received his B.A.Sc. degree with distinction in electrical engineering from the University of Toronto in 2017 and worked in image/video processing at Qualcomm in 2015-16. Currently, he is a graduate research assistant at the Multimedia Lab at the University of Toronto and studying for his M.A.Sc. degree in electrical engineering under the co-supervision of Professors Konstantinos Plataniotis and Parham Aarabi. His research focus is on the weakly-supervised semantic segmentation of histological tissue type from digital pathology images. He has also been involved in formulating the histological tissue type framework of the ADP database, revising the patch annotations, and analyzing the annotation quality through deep learning.

Alfred Chan
MASc ECE student at University of Toronto

Alfred Chan is Alfred Chen and he is a M.A.Sc candidate in the Communications Group of Electrical Engineering at the University of Toronto. he is under the supervision of Prof. K. N.
