  • Image interpolation for motion/disparity compensation
    Patent number: 8670075
    Abstract: Methods of image interpolation disclosed herein include a method of irregular-grid expanded-block weighted motion compensation (IEWMC) and a method of block-wise directional hole interpolation (BDHI). The IEWMC can be used with unidirectional motion or disparity trajectories. The IEWMC can be applied in both forward and backward directions, and the interpolated images resulting from IEWMC application can be superimposed, or averaged, to reduce the blocking artifacts and handle the holes and overlaps. The BDHI takes into account the orientation of local edges and textures when filling the holes, which results in a sharper interpolated image.
