A new method for achieving Electro-Holographic Display systems was developed and tested with very promising results. There were many parts which composed Holography 3D-TV system in the lens and so on, and a system was complicated in the method proposed the last time. Therefore, the miniaturization of TV was very difficult. In this paper, we will examine about the miniaturization of 3D TV system by lens-less technique.
To obtain realistic computer graphics, there are various methods which simulate optical phenomena such as reflection, refraction and chromatic dispersion. However, there are no computer graphics software that can simulate diffraction of holograms and gratings. In this paper, we studied expression methods of diffraction for computer graphics and obtained some results of 2-D gratings as the first step.
3D video is the ultimate image medium recording a dynamic visual event in the real world as is. The recorded object can be observed from any viewpoint, because 3D video records an object's full 3D shape and its surface properties(i.e.color and texture). Recently, methods of creating arbitrary object views from multi-viewpoint images have been proposed. Although some methods do not reconstruct an object's 3D shape, we believe the explicit representation of the 3D shape is required for object action recognition and versatile editing of multiple 3D videos. This paper presents methods of 1) transforming voxel representation of an object into polygonal representation, 2) generating texture on the surface patches from multi-viewpoint images, 3) visualizing 3D video with versatile camera works and object-background configuration.
