Context: Light field cameras are cameras that capture the orientation of the rays of light entering its optical system [1]. This makes it possible to recover the 3D geometry of the observed scene from a single image. Our study currently focuses on the behavior of this type of sensor when the scene is moving during the acquisition of this light field, considering that the camera is equipped with a rolling shutter sensor, and that, consequently, all the pixels are not exposed at the same time [2].

This internship is part of a project carried out between the ICB Laboratory and the Femto-st Institute (Besançon)[3].

Mission: The recruited intern will be tasked with exploring one of the issues encountered by the interaction between light field and rolling shutter. The precise subject will be set up with the candidate before the start of the internship according to their preferences and skills profile. The potential missions are quite diverse in the field of computer vision, like for example:

• - sizing the optical assembly of an experimental light field camera

• - the application of machine learning methods for estimating depth maps adapted to the problem

• - the application to robotics (probably in simulation)
