Abstract
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 and a crop window transform may accordingly be determined. The crop window transform may describe a transform of the original camera path to a modified camera path that is smoother than the original camera path. A smoothness metric indicative of a degree of smoothness of the modified path may be determined. Based on a comparison of the smoothness metric to a predetermined threshold, for example, the crop window transform may be applied to the original video to obtain a stabilized modified video.
