MSc Sergio Moreschini :

MSc Sergio Moreschini

Light Field (LF) data is rich from different point of views: it is acquired from multi-modal devices which provide a representation that is dense both in spatial and angular resolution, and therefore the amount of data generated from this process is overwhelming. The scope of Sergio's research is to investigate the optimal Enhanced LF representation: a representation that offers a good compromise between the amount of data and the completeness of the scene representation based both on images and geometry information.

MSc Filipe Gama :
