Stereo 3D reconstruction is continuously increasing its popularity in the study of mid-to small-
scale sea waves. In the recent past, different approaches have been proposed to reconstruct
the space-time sea surface elevation field from synchronized stereo frames. Usually, the
reconstruction is performed by first recovering a dense and sparse 3D point cloud from
stereo pairs and then by interpolating it into a regular grid. Even considering state-of-the-art
methods, with typical image resolutions, it's unlikely to perform the first step in less than …
