Abstract
A first image and a second image recorded during a video capture event is obtained. A correction factor is computed based at least in part on a target interval and an interval of time between recording the first image and recording the second image. A motion value is computed based at least in part on a difference between the first region and the second region, with the first region and the second region both containing a reference object present in the first image and the second image. A normalized motion value is provided based at least in part on normalizing the motion value according to the correction factor.
