Abstract :
There are several representations for 3D scene that are used for 3DTV and free viewpoint imaging systems. A well-known representation is sparse view-plus-depth. Based on view-plus-depth, layered depth video (LDV), and FTV data Unit (FDU) were proposed. The represented images by them are based on residual values. For view data in view-plus-depth, we propose a novel representation; consist of original and hybrid images that are repeated consecutively. A hybrid image has residual and reminder pixels. A virtual image is synthesized in both generation and reconstruction of the hybrid image. The reconstruction is the compensation of the virtual image using the hybrid image. The reconstructed hybrid image has higher PSNR and fewer visible artifacts than the virtual view compensated by residual or reminder image. The data size of the hybrid images is also less than residual and reminder images.
