Abstract(ENG)

Multi-view system is one of the auto-stereoscopic displays that allows users to watch 3D images without wearing special glasses. Generating contents for the multi-view display system is often accomplished using Depth-image-based rendering (DIBR) intermediate view generation. DIBR-based intermediate view generation method reconstructs a 3D scene with a color image and depth map information. Then, a virtual camera is put in various view positions to capture intermediate view images. In this research, we tried to improve the quality of the DIBR-based intermediate views by applying non-uniform quantization method for depth map information. This paper describes the intermediate view generation process using DIBR. Then, it discusses the evaluation of multi-view intermediate images generated using uniform and non-uniform depth quantization methods. Finally, the paper describes the future direction and how the muti-view systems can be utilized in computer games.
