Abstract
According to an example, 3D modeling motion parameters may be simultaneously determined for video frames according to different first and second motion estimation techniques. In response to detecting a failure of the first motion estimation technique, the 3D modeling motion parameters determined according to the second motion estimation technique may be used to re-determine the 3D modeling motion parameters according to the first motion estimation technique.
