ABSTRACT:
A method for displaying a video sequence depicting motion of at least one video object by sequential presentation of a plurality of frames includes storing a low resolution representation of the video object, generating and displaying a first frame of the sequence based on the low resolution representation, updating the low resolution representation, and generating and displaying a subsequent frame of the sequence based on the updated representation. The method may include calculating a quality metric to determine when updating is necessary.
