Frame interpolation apparatus and method |
摘要 |
<p>A first motion vector points from a source region of a source picture to a destination region of a destination picture. A second motion vector is scaled from the first motion vector based on a first temporal distance between the source picture and the interpolation picture. A third motion vector is scaled from the first motion vector based on a second temporal distance between the destination picture and the interpolation picture. A weight of a first interpolation region of the interpolation picture is calculated using distortion energy of the source region. A first motion compensation picture compensated from the source region to a temporal position of the interpolation picture using the second motion vector, and a second motion compensation picture compensated from the destination region to the temporal position using the third motion vector are calculated. A third motion compensation picture is calculated by weighted-averaging the first motion compensation picture and the second motion compensation picture. A second interpolation region of the interpolation picture is calculated by averaging a region of the third motion compensation picture and a region of an artifact prevention picture with the weight.</p> |
