Viewpoint-aware Segment Streaming for Free Navigation of Light-field Images
Won-Ki Seo,Chae Eun Rhee 대한전자공학회 2020 IEIE Transactions on Smart Processing & Computing Vol.9 No.2
Virtual reality (VR) is drawing a lot of attention as a future killer application that may surpass the era of two-dimensional video. However, VR still has many technical bottlenecks and challenges that should be overcome for wide application. Image quality and interaction should be improved to increase the immersion level for users. This drastically increases the amount of image data needed for rendering. At the same time, the image should be transmitted without intermittence in a network environment having limited bandwidth. This paper proposes a streaming scheme supporting free navigation in a light field–based VR system. The proposed viewpoint-aware streaming of light-field data focuses on the fact that image data can be reused in active exploration of spaces, in contrast to passive video watching. The quantity of data transmission may be significantly decreased by employing a cache in user devices.

This research aims to attract patients of AMA(Against Medical Advice). The patients are neglected because they are a few, but the patients are very important for hospital income. So, this study analysis patients of AMA. The analysis items are 1) a course of hospital, 2) health delivery system, 3) whether or not consultant, operation and transfer, 4) principle diagnosis, 5) specialty fields, 6) length of stay, so on. The results show that AMA of male, old, and emergency case is high. In principle diagnosis, AMA of cerebral infaction and fracture and liver disease is high. Therefore it's meaningful research for hospital management.
