The most compelling evidence supporting the use of low dose computed tomography in the screening of high risk populations for lung cancer was generated by the National Lung Cancer Screening Trial carried out in the United States by the National Cancer Institute and the American College of Radiology Imaging Network.[1] This trial was a randomized prospective study which included over 53,000 part...

In contrast to traditional video, immersive video allows viewers to interactively control their field of view in a 360ı panoramic scene. However, established methods for the comparative evaluation of gaze data for video require that all participants observe the same viewing area. We therefore propose new specialized visualizations and a novel visual analytics framework for the combined analysis...

3-D cinematography is a new step towards full immersive video, allowing complete control of the viewpoint during playback both in space and time. One major challenge towards this goal is precise scene reconstruction, either implicit or explicit. While some approaches exist which are able to generate a convincing geometry proxy, they are bound to many constraints, e.g., accurate camera calibrati...

This paper describes a system for structure-from-motion using vanishing points and three-dimensional lines extracted from omni-directional video sequences. Two novel aspects of this work are its deferred initialization of features using noisy observations from multiple, uncertain vantage points, and its use of dynamic programming for efficient 3D line tracking. We show preliminary results from ...

In this paper, we propose a recording system for a round-table meeting using microphone array as well as omnidirectional video camera. These equipments are located at the center of the table, and record all the activity during a meeting. They are also used for estimating the directions of speakers, and such data is exploited for reproducing the frontal image of the speaker from omnidirectional ...
