This paper describes the development of a ubiquitous information system named "dokodemo-display" system. It is a display-centric communication system, which is portable, interactive, and collaborative. The objective of "dokodemo-display" system is to increase the value of a place with helping to form local communities at that place. It provides information(More)
In this paper, we consider the rate-distortion performance of a multi- view image set with subsampling of the viewpoints. As a basic analysis, we compare two scenarios: (i) all images would be coded and transmitted in even quality, and (ii) a half of the images would be discarded by subsampling at the sender side, and the remaining half would be coded and(More)
This paper presents a method that jointly performs synthesis of free-viewpoint images and object segmentation from that viewpoint. This method works efficiently and online by sharing a certain calculation process among rendering and segmentation steps. Since the segmentation is performed for arbitrary viewpoints directly, the extracted object can be(More)
Free-viewpoint image synthesis (FVIS) refers to the process of generating novel viewpoint images from a set of multi-view images. Most of the conventional FVIS methods were based on image blending, so that they are subject to a fundamental limitation in resolution: the output resolution is lower than or at most equal to that of the input images.
