William is a PhD student in the Bioimage Analysis Unit under the joint supervision of Elsa Angelini (LTCI, Telecom ParisTech, Paris) and Jean-Christophe Olivo-Marin (Bioimage Analysis). His work consists in investigating on application of the Compressed Sensing (CS) theory in the field of biological microscopy. This mathematical framework states that it is possible, under certain constraints, to reconstruct a high-quality image from very fewer samples than the full acquisition. His first results have consisted in the development of a CS-based denoising algorithm, which led to segmentation results in the context of SD-OCT imaging. His current work is more theory-based, as he is seeking for fundamental results to apply CS in new microscopy experiments.
Compressive Sensing in biological imaging
We are investigating a new global framework for smart acquisition methods in biological imaging whereby it is possible with mathematical tools to recover a high quality image from very fewer samples than the full […]
