Physics + learning + optimisation
We design and develop deep-learning image reconstruction methods inspired by physical modelling and optimisation schemes.
CIL
In our unit, we combine physical and mathematical modelling with optimisation and learning techniques to develop robust image reconstruction methods that perform effectively even under limited training data and potentially complex physical models. We focus particularly on modelling spatial distortions, non-Gaussian noise statistics, and the stochastic, time-dependent dynamics that arise in various fluorescence microscopy modalities. Our ultimate objective is to integrate these models into innovative reconstruction methods that fuse physics, optimization, and (deep) learning approaches.
Research topics
Self-adaptive algorithms
We develop algorithms for solving large-scale problems with minimal user dependence.
Breaking the diffraction barrier
Our team aims at developing computational tools to overcome the resolution limit set by light diffraction in fluorescence microscopy.
Digital Humanities
Advanced digital image processing tools unveil the invisible in ancient paintings and illuminated manuscripts.
Computational imaging in action
Our computational approaches are applied to solve challenging problems arising in a plethora of applications ranging from medical imaging to computational neuroscience.
