## Abstract
Motion estimation and compensation in holographic videos requires extracting and analyzing 3D geometry variations from the signal holographic. Unfortunately recovering the scene from a single hologram numerical is an ill-posed inverse problem for which no exact solution does not exist. Indeed, the light wave diffused by each point of the scene contributes at each pixel when recording the hologram. Therefore, the signal holographic blurs 3D scene information, which cannot be retrieved directly. In particular, a slight change in the scene translates by very different holographic patterns, making motion estimation a non-trivial research topic. The goal here is to study what a computer-generated hologram is and how it compares to a traditional image.
