AUTOMATIC COMPOSITION OF VIDEO WITH DYNAMIC BACKGROUND AND COMPOSITE FRAMES SELECTED BASED ON FRAME CRITERIA

摘要

A processing device generates composite images from a sequence of images. The composite images may be used as frames of video. A foreground/background segmentation is performed at selected frames to extract a plurality of foreground object images depicting a foreground object at different locations as it moves across a scene. The foreground object images are stored to a foreground object list. The foreground object images in the foreground object list are overlaid onto subsequent video frames that follow the respective frames from which they were extracted, thereby generating a composite video.

1. A method for generating a composite output video from an input video having a sequence of frames, the method comprising:
receiving a current video frame for processing from the sequence of frames; determining, by a processing device, whether the current video frame meets first criteria; responsive to the current video frame meeting the first criteria, performing, by the processing device, a foreground/background segmentation based on a predictive model to extract a foreground object image from the current video frame, the foreground object image comprising a representation of a foreground object depicted in the current video frame with background pixels subtracted, and storing the foreground object image to a foreground object list that stores a plurality of previously extracted foreground object images; and overlaying each of the foreground object images in the foreground object list onto the current video frame to generate a composite video frame.
