A New Virtual View Rendering Method based on Depth Map for 3DTV

摘要

Virtual view rendering is one of the key technologies to realize Three-Dimensional Television (3DTV) system, but which still exists, such as false contour, holes and other issues. In this paper, these problems are been effective solved. First, we use the connection of pixel coordinate warping between reference image and virtual image in the rendering process, to make quick decision on the position of hole region and its edge and then utilize the way of outward expanding the edge of holes to cover residual or warping error pixels; then eliminate false contour by image synthesis with the left and right view images from rendering based on the location of holes; finally, we use mean filter and the image restoration method of total variation model to fill holes. The experimental results show that the proposed method improves the quality of virtual view images from rendering.
