Methods and systems for processing a video for stabilization using dynamic crop

摘要

Methods and systems for processing a video for stabilization are described. A recorded video may be stabilized by removing at least a portion of shake introduced in the video. An original camera path for a camera used to record the video may be determined. A crop window size may be selected, a crop window transform may accordingly be determined, and the crop window transform may be applied to the original video to provide a modified video from a viewpoint of the modified motion camera path.

1. A method comprising:
determining an estimation of an original motion path of a camera that recorded a video; selecting a crop window size being less than a size of a video frame of the video; determining a crop window transform to transform the original motion path of the camera to a modified motion camera path, wherein a crop window associated with the crop window transform is constrained to the crop window size; identifying a first smoothness metric indicative of a degree of smoothness of the modified motion camera path; applying the crop window transform to crop the video, in view of the crop window and the first smoothness metric, and to provide a modified video from a viewpoint of the modified motion camera path; and performing an additional modification of the modified video using a second smoothness metric corresponding to a reduced crop window size.
