If scene flow expressed in three-dimensional (3D) vector fields is robustly estimated from multi-view or multi-focus images, we can develop advanced 3D motion tracking and motion compensation for 3D video compression. In this study, based on a synthesis of multi-focus images from multi-view images, we propose a novel method for analyzing 3D scene flow accurately at low computational cost as an extension...
Scene refocusing beyond extended depth of field for users to observe objects effectively is aimed by researchers in computational photography, microscopic imaging, and so on. Ordinary all-in-focus image reconstruction from a sequence of multi-focus images achieves extended depth of field, where reconstructed images would be captured through a pinhole in the center on the lens. In this paper, we propose...
Light-Field enables us to observe scenes from free viewpoints. However, it generally consists of 4-D enormous data, that are not suitable for storing or transmitting without effective compression. 4-D Light-Field is very redundant because essentially it includes just 3-D scene information. Actually, although robust 3-D scene estimation such as depth recovery from Light-Field is not so easy, a method...

In this paper, a novel method of real-time free viewpoint image reconstruction by FPGA from multiple differently focused images is described in detail. Our previously proposed high-speed free viewpoint image reconstruction method is composed of deterministic parallel processes without conditional branches. Therefore, it is very effective for the method to be implemented to hardware such as FPGA. Actually,...
