    We present some recent results on the use of geometric and variational techniques to solve problems in computer vision. The thrust of the paper is that a mathematical approach to problems is relevant, without necessarily giving up efficiency in applications. We illustrate our ideas with several examples in the area of surveillance, augmented reality, and image synthesis View full abstract»

    At ATR Media Integration & Communications Research Laboratories, our research group is aiming at realizing virtual communication environments in which the users at remote sites can feel that they are virtually co-located. This paper presents the ongoing research in two subareas chosen to address this problem: (a) Generating human images in virtual scenes. (b) An image based approach for genera... View full abstract»

    The Nonfrontal Imaging Camera (NICAM) simultaneously provides omnifocused intensity and range panoramics (i.e., panoramic intensity images and depth maps). In this paper, we describe the estimation of range which is based on focusing. An analysis of errors in the range estimates is presented along with examples of experimental results. The image and depth map are combined to approximate and recons... View full abstract»

  • Toward interactive scene walkthroughs from images

    Interactive walkthrough applications require rendering an observed scene from a continuous range of target viewpoints. Toward this end, a novel approach is introduced that processes a set of input images to produce photorealistic scene reprojections over a wide range of viewpoints. This is achieved by (1) acquiring calibrated input images that are distributed throughout a target range of viewpoint... View full abstract»

  • A visual/haptic interface to virtual environment (WYSIWYF display) and its application

    VR training or skill transfer via virtual environment is a kind of human communication from one (expert) to others (trainee). To build a VR training system for visuo-motor skills, a visual interface should be correctly registered to a haptic interface so that the visual sensation and the haptic sensation are consistent spatially and temporally. Ideally a visual/haptic interface should be configure... View full abstract»

    Camera calibration and the acquisition of Euclidean 3D measurements have so far been considered necessary requirements for overlaying three-dimensional graphical objects with live video. We describe an image-based approach to augmented reality that avoids both requirements: it does not use any metric information about the calibration parameters of the camera or the 3D locations and dimensions of t...

  • Displaying motion parallax by occlusion detectable stereo

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (292 KB)

    We propose a 3D image display system which can present real scenes with realistic motion parallax. In the sensing system, a scene is observed by using a camera matrix. An excellent stereo algorithm SEA which utilizes 3×3 image matrix recovers the depth information of the scene with the density and the sharpness required for high quality image generation. In the display system, following the ... View full abstract»

    Conventional T.V. cameras are limited in their field of view. A real-time omnidirectional camera which can acquire an omnidirectional (360 degrees) field of view at video rate could be applied in a variety of fields such as autonomous navigation, telepresence, virtual reality, remote monitoring. We have developed a new omnidirectional image sensor named HyperOmni Vision which consists of a CCD cam... View full abstract»

    In the applied fields of Virtual Reality and 3D graphics, communications is very important. Among that line, we are doing research in virtual reality to create suitable environments for better communications. This paper is concerned with user interface technologies for a virtual communication space. First, we introduce the concept of a VR system, the “Tel-E-Merge” system, in which user...

    This paper introduces prominent topics of our Mixed Reality (MR) project and states what kind of role computer vision and graphics play in the project. MR is a part of VR in broader sense, but it treats the physical space as well as the virtual space created in computers. Here we use the term “mixed reality” instead of often used “augmented reality” (AR). This is because MR... View full abstract»

    Virtual Reality has traditionally relied on hand-created synthetic virtual worlds as approximations of real world spaces. Creation of such virtual worlds is very labour intensive. Computer vision has recently contributed greatly to the creation of the visual/graphical aspect of the virtual worlds. These techniques are classified under image-based-as opposed to geometry-based-rendering in computer ... View full abstract»

    We present our long-term effort focused on building a 3-D model acquisition system for teleimmersion applications. In our project we stress fast processing and high fidelity of the result: it is not just geometric accuracy of the recovered geometric model but also radiometric correctness of the recovered surface texture. We suggest that single-type geometric model is not sufficient for modeling la... View full abstract»

    Despite what we have heard from the mass media, Virtual Reality technology is still in its infancy. Numerous research prototypes have suggested that this technology will be meaningfully applied to seven general applications. This paper describes development of a general visualization system that has been applied to the domains of virtual walkthroughs and the visualization of abstract information View full abstract»
