ABSTRACT:
Methods and apparatus, including computer program products, implementing and using techniques for masking and extracting a foreground portion from a background portion of a digital video. An input defining an initial border region is received, which includes a border between a foreground portion and a background portion of an initial digital image in a digital video. A border region for another digital image in the digital video is generated. The initial and automatically generated border regions are used for masking the foreground portion from the background portion in the digital video.
