Duties

The successful candidate will have the opportunity to conduct research in the field of geomatics, remote sensing and computer vision. The focus of this research concerns two elements related to super resolution technique for Digital Elevation Models (DEMs).
1) Generation of Accurate Training Data.
This research aims to develop methods for downsampling high-resolution Digital Elevation Models (DEMs) to generate training data for super-resolution models. Traditional downsampling techniques, such as bicubic downsampling, often fail to preserve critical topographic features like peaks and breaklines. Therefore, this study will investigate adaptive downsampling techniques to better maintain these important features in the training data.

2) Exploration of Transformer-Based Models for Super-Resolving DEMs.
This research focuses on leveraging transformer-based models to enhance the resolution of Digital Elevation Models (DEMs). The attention mechanism inherent in visual transformers (ViT) captures both local and global patterns, as well as relationships across different parts of the input. This capability is particularly advantageous for accurately super-resolving DEMs, as topographic features often extend over large areas. Furthermore, advanced visual transformers have demonstrated superior performance in super-resolution tasks compared to traditional CNN-based methods.
The successful student will have the opportunity to interact with CCMEO staff, researchers and technicians. The day-to-day work will take place at the University.

The successful candidate should have a good work ethic, a strong sense of responsibility, and the ability to work in team environments.

Preference will be given to a Canadian citizen and a permanent resident of Canada.

This position will start in May 2025.
