Patent Images

1. A method for at least one of encoding and decoding a digital image, comprising:

  • (a) identifying a first region adjacent a second region in said image, wherein said first region and said second region are substantially the same size;

    (b) identifying a first set of one or more motion vectors calculated using information only from said first region and a second set of one or more motion vectors calculated using information only from said second region; and

    (c) irrespective of whether or not said first region has non-zero transform coefficients, selectively not filtering the boundary area between said first region and said second region based on a relationship between said first set of one or more motion vectors and only said second set of one or more motion vectors.
