I started my research career with an interest in computer graphics and image processing. During my PhD studies I looked at applications of differential geometry in polygonal mesh processing and then moved towards computer vision, where I investigated and developed real-time, short range structured light scanning solutions for 3D reconstruction and 3D face recognition. When I joined the Vision and Learning research group at Stellenbosch my focus shifted more to the application of machine learning principles in computer vision. I have collaborated on a few projects with the Electronic Systems Lab where we develop computer vision techniques for autonomous navigation, as well as the CSIR's Modelling and Digital Sciences unit where we apply machine learning to various environmental domains. My current interests include deep learning for image and video analysis, the combination of vision and natural language, and visual knowledge representation. I am also one of the creators and coordinators of Maties Machine Learning, a discussion forum and interest group spanning all relevant disciplines at Stellenbosch University.
Here is a list of some of the research projects that I am or have been involved with. I am in the process of creating a project page for each, with more detailed information, so please check back soon.
