Title: Generative Models of 3D and 4D Shapes
Abstract
In this talk, I will review our latest work on generative models for 3D and 4D shapes. By 4D shapes, we refer to 3D objects whose shape deform over time as the result of their motion, interaction with their environment, and their (normal/abnormal) growth. Modelling, mathematically, such dynamic processes is crucial for many applications ranging from biology and health to computer graphics and virtual reality. I will particularly focus on our latest work that combines differential geometry and statistics for modelling spatiotemporal variability in 4D shapes.
Short biography of the speaker
Hamid LAGA is currently a professor in Computer Science at Murdoch University (Australia). His expertise is in Machine Learning, Computer Vision, and Computer Graphics. While his primary focus is on fundamental research, he undertakes cross-disciplinary and translational research across agriculture, animal science, biosecurity and health. His research interests include: (1) 3D reconstruction, modelling and analysis of static and dynamic objects, using tools from artificial intelligence, machine learning, statistics and differential geometry. In addition to solving the underlying fundamental problems, he also targets applications such as modelling and simulation in computer graphics, medical diagnosis, and sports analytics. (2) virtual and augmented reality in Health, and (3) machine learning, computer vision and image processing for Health, Agriculture and Biosecurity. He co-authored two books published, respectively, in 2017 and 2019, and more than 40 articles in top journals including IEEE Transactions on Pattern Analysis and Machine Intelligence and ACM Transactions on Graphics (Siggraph). His work received multiple awards including the Best Paper Awards at (1) the Eurographics Symposium on Geometry Processing (2017), (2) the APRS/IAPR Best Paper Prize at DICTA (2012), and (3) the IEEE International Conference on Shape Modelling (2006). He has also received the Japan Society of Art and Science Award (2008) for the best computer graphics paper published between 2006 and 2008.
