Patent Images

1. A method, comprising:

  • recognizing, by a set top box comprising a processor, a portion of a video stream in an Internet Protocol TV network having video compression artifacts corresponding to a stored model, the stored model including an image or a video model of an image background;

    performing, by the set top box, model-based video correction of the portion recognized using synthetically generated images of objects in a captured video scene; and

    delivering, by the set top box, to a presentation device a corrected portion of the video stream over a low bit rate connection,wherein the model-based video correction corresponds to synthetic replacement of the artifacts according to a stored model of replacement images,wherein recognizing the portion of the video stream further comprises recognizing, within a captured video, a predetermined amount of compression artifacts for the portion of the video stream for an object having a stored corresponding model for the object, andwherein the model-based video correction is a physical model based enhancement to a video image; and

    creating a partially synthetic image of a face to correct a portion of a video stream having video compression artifacts corresponding to a stored model of the face.
