    Generation of Omnidirectional Image Without Photographer

    In order to create a virtual reality (VR) space using omnidirectional images, it is desirable to use images without the photographer’s inclusion. In this study, we propose a method to generate an omnidirection...

    Ultra-Shallow DoF Imaging Using Faced Paraboloidal Mirrors

    We propose a new imaging method that achieves an ultra-shallow depth of field (DoF) to clearly visualize a particular depth in a 3-D scene. The key optical device consists of a pair of faced paraboloidal mirro...

    AR image generation using view-dependent geometry modification and texture map**

    Augmented reality (AR) applications often require virtualized real objects, i.e., virtual objects that are built based on real objects and rendered from an arbitrary viewpoint. In this paper, we propose a meth...

    From Image Inpainting to Diminished Reality

    Image inpainting, which removes undesired objects in a static image and fills in the missing regions with plausible textures, has been developed in the research fields of image processing. On the other hand, D...

    Generation of an Omnidirectional Video without Invisible Areas Using Image Inpainting

    Omnidirectional cameras usually cannot capture the entire direction of view due to a blind side. Thus, such an invisible part decreases realistic sensation in a telepresence system. In this study, an omnidirec...
