    Abstract :

    Depth Image Based Rendering is a 2-D to 3-D conversion technology that is widely used in applications like 3D TV and auto-stereoscopic displays. Holes will be present in the virtual views generated if the depth map is not complete. This work proposes a new method to reduce the holes produced in the virtual views generated in Depth Image Based Rendering. Since holes occur in the rendered view when depth map changes significantly smoothening methods were proposed. Gaussian filtering affected the edges and caused distortions in the rendered view. Gaussian filtering also costs a lot in terms of computation time. This work proposes a median filter to pre-process the depth map. Median filtering preserves the edge information of the depth map and results in a high quality rendered view compared to Gaussian filtering methods. The result shows that the proposed method results in high PSNR and SSIM values compared to existing methods. The number of holes in the rendered view also reduces along with the computation time.
