Depth Image Based Rendering
Image-Based Rendering (IBR) techniques, which have been considered to be an efficient way of generating novel views from a series of original views, have received much attention in recent ten years. Compared with other IBR techniques, Depth-Image-Based Rendering (DIBR) techniques Deed less reference images as the depth information is also used. As a key technology in advanced Three-Dimensional Television (3D-TV) system5 , DIBR has a promising perspective. In this paper, a depth image based rendering system is proposed, different from the DIBR techniques used in advanced 3DTV, our method focus on generating an arbitrary new view instead of a virtual left view or right view. We first use an edge dependent filter to smooth the sharp changes in depth image so as to reduce the big holes. Then we do 3D Image Warping using the known calibration parameters, In order to deal with the visibility problem quickly, we process the pixels of the original images in an occlusion-compatible order10. Thirdly, we merge two generated images to eliminate the big holes in desired view. Finally we fill in the remaining holes with an interpolation method. Experimental results have show that the proposed method can provided a satisfactory image quality.
