Alexander Wong

Alexander Wong is an Assistant Professor in the Systems Design Engineering department and Co-Director of the Vision and Image Processing (VIP) Research Group at the University of Waterloo. He is also the Canada Research Chair in Medical Imaging Systems.

His research interests revolve around imaging, image processing, computer vision, pattern recognition, and cognitive radio networks, with a focus on the hardware-software design of integrative medical imaging systems, and biomedical and remote sensing image processing and analysis. He is also interested in multimedia management systems and 3D graphics and game development.

One of Professor Wong’s key research interests is medical image processing and analysis with applications to prostate, breast, lung and dermatological cancer analysis. He is developing an improved Magnetic Resonance Imaging (MRI) system that recognizes cancer indicators such as tissue characteristics, size and shape. This will allow for enhancements to early stage cancer detection and the capturing of data in a more efficient manner.

He has published refereed journal and conference papers, as well as patents, in various fields such as imaging, computer vision, graphics, image processing, multimedia systems, and wireless communications. Professor Wong is the co-author of the textbook “Data Structures and Algorithms in a Nutshell’ and has also co-authored the chapter “Melanoma decision support using lighting-corrected intuitive feature models” in Computer Vision Techniques for the Diagnosis of Skin Cancer. Additionally, he co-wrote the chapter “Nonparametric sample-based methods for image understanding” in Emerging Topics in Computer Vision.

As a result of his research work, Professor Wong has received multiple awards such as the Early Research Award from the Ministry of Economic Development and Innovation, as well as the Alumni Gold Medal from the University of Waterloo in 2012. In 2009 and 2014, he received Best Paper Awards from the Canadian Image Processing and Pattern Recognition Society (CIPPRS). He also received two Outstanding Performance Awards, an Engineering Research Excellence Award, as well as a Distinguished Paper Award by the Society of Information Display (2015).

Professor Wong holds 3 patents and 10 patent applications in the area of imaging.
