Abstract

Multifocus acquisition provides a way to reconstruct high resolution images from a 3D scene by capturing a sequence of multiple focal planes along the optical axis of the camera. Since the capture of multifocus images is not simultaneous but relies on a temporal sequence of captures while focusing at different focal planes the multifocus method is usually limited to static scenes. However since the development of high speed electrically focus tunable lenses it is also possible to reconstruct dynamic scenes from multifocus acquisition provided that the time to perform a complete sweep along z axis is much shorter than the time involved in the dynamic scene. In the present work we propose all-in-focus reconstruction of a 3D dynamic scene from multiple-multifocus captures.
