Abstract:
1. A method for processing a video, comprising: estimating an original motion path of a camera that recorded the video; determining a first derivative, a second derivative, and a third derivative of the original motion path of the camera with respect to time; determining a modified motion camera path of the original motion path of the camera based on a weighted combination of the first derivative, the second derivative, and the third derivative of the original motion path of the camera; based on the modified motion camera path and the original motion path of the camera, determining a crop window transform that describes how to modify the original motion path of the camera to the modified motion camera path, the crop window transform determined according to at least one constraint limiting changes to the original motion path of the camera; and applying the crop window transform to the video to recast the video from a viewpoint of the original motion path of the camera to a viewpoint of the modified motion camera path.
