Group meeting around a table involves multiple people. Analyzing the communication of group meetings needs to under-stand the interaction among multiple people. In this paper, we propose a method of gaze estimation for four-person-table-meeting by using ...

Many people with visual impairments would like to take photographs. However, they often have difficulty pointing the camera at the target. In this paper, we address this problem by proposing a novel photo-taking system called VisPhoto. Unlike ...

In recent years, as people become more health-conscious, dietary management has become increasingly important. Existing methods record only one person’s meals or eating movements, but cannot record the meals of multiple people at the same time. ...

Video communication systems have been suffered from the narrow field of view. To solve this limitation, one study proposed symmetric 360° video communication system by combining an omnidirectional camera and a hemispherical display. However, the system ...

This paper deals with the problem of 3D human tracking in catadioptric images using particle-filtering framework. While traditional perspective images are well exploited, only a few methods have been developed for catadioptric vision, for the human ...

This paper introduces a telepresence system called OmniGaze, which displays a remote user's presence using a spherical display on an omnidirectional camera. In a telepresence system, gaze has a variety of important functions such as presenting the ...

We propose an omnidirectional projection system embedding a projector with an ultra wide-angle lens in the table. AR markers are attached on the target surfaces so that the system can track them with an omnidirectional camera. Finally, we developed a ...

We propose OmniEyeball (OEB), which is a novel interactive 360° image I/O system combining a spherical display system with an omnidirectional camera. We also present our experimental design of a user interface on the OEB, including a vision-based touch ...

This paper proposes a generation method of immersive bullet-time video that continuously switches the images captured by multi-viewpoint omnidirectional cameras arranged around the subject. In ordinary bullet-time processing, it is possible to observe a ...

We propose OmniEyeball (OEB), which is a novel interactive 360° image I/O system. It integrates the spherical display system with an omnidirectional camera to enable both capturing the 360° panoramic live streaming video as well as displaying it. We also ...

This research describes the development of a system that estimates the natural postures of a user's fingers from the images captured by an omnidirectional video camera attached to the center of the user's palm in real time. The finger postures can be ...

Panoramic vision is widely applied in the field of computer vision, such as video -conference, Robotic navigation and Security Monitoring. Omnidirectional vision system can provide image with 360° as a field of view. In many applications, its useful to ...

Recent years have seen the emergence of a new way to watch sports, that is, watching them from the ball's point of view (POV) taken with cameras embedded in the ball. The problem, however, is that the ball's POV is unstable since the ball spins. In this ...

Recently, 360-degree panorama and spherical displays have received more and more attention due to their unique panoramic properties. Compared with existing works, we plan to utilize omnidirectional cameras in our spherical display system to enable ...

Regarding the autonomous of robot navigation, vanishing point (VP) plays an important role in visual robot applications such as iterative estimation of rotation angle for automatic control as well as scene understanding. Autonomous navigation systems ...

In recent years, classical structure from motion based SLAM has achieved significant results. Omnidirectional camera-based motion estimation has become interested researchers due to the lager field of view. This paper proposes a method to estimate the ...

A remote view system is a system for the delivery and presentation of information such as video and audio to users in remote locations. Methods for the construction of virtual environments based on video information have been applied to remote view ...

This paper describes a method for acquiring full spherical high dynamic range (HDR) images with no missing areas by using two omni directional cameras mounted on the top and bottom of an unmanned airship. The full spherical HDR images are generated by ...

In this paper, we developed an image-based indoor localization system using omnidirectional panoramic images to which location information is added. By the combination of the robust image matching by PCA-SIFT and fast nearest neighbor search algorithm ...

Our work and living environments are increasingly populated by devices which integrate computational ability and intelligence. The Nomad Biometric Authentication (NOBA) project focuses on the development and implementation of biometric technologies for ...
