Computational Imaging and Displays: Capturing and displaying richer representations of the world

Computational imaging techniques allow capturing richer, more complete representations of a scene through the introduction of novel computational algorithms, overcoming the limitations imposed by hardware and optics. The areas of application range from medical imaging to security, to areas in engineering, to name a few. Computational displays combine optics, hardware and computation to faithfully reproduce the world as seen by our eyes, something that current displays still cannot do. This article looks at a few examples of both, aiming to convey the power of the joint co-design of hardware and computational algorithms, also taking into account visual perception.
