Directional adaptive hole filling for new view synthesis

In this paper, a new hole filling method based on the direction of background image texture for new image view synthesis is presented. Strong texture gradient of background pixel is traced along its direction to obtain the texture orientation. Then texture direction map is computed for the hole pixels, based on the texture orientation. Finally, the hole pixels are filled by the background pixels along the direction guided by the texture direction map. This is to produce natural texture in the hole regions, while reducing blur, and preventing distortion in the foreground objects. Thus, high quality new image view can be achieved, even with large baseline synthesis. When the images are used for 3D viewing, the 3D effect is enhanced.
