Improvement of Human-Object Observation System
Kazuki YOKOI,Mihoko NIITSUMA,Hideki HASHIMOTO 제어로봇시스템학회 2009 제어로봇시스템학회 국제학술대회 논문집 Vol.2009 No.8
In this paper, we will present an improved system which observes human activities. We have tried to describe the activities by objects usage because there are so many kinds of objects in environments and people use them to accomplish their activities. Therefore, by observing objects we can extract more information about activities of human and this may help us to estimate what people are doing in the space. Methods to obtain objects usage are explained and improved in this paper. We also evaluated the system from experiments.

In radiotherapy, quality assurance (QA) for beam delivery from linear accelerator (linac) of treatment machine is a highly crucial factor for accurate radiotherapy because of the fuctuations in the conditions of the machine. The radiation feld is one of the important evaluation items, and this has been well-checked by crossline (right-to-left) and inline (caudal-to-cranial) profles. Diagonal or angular profles of the radiation feld are also an important component of irradiation feld; however, these are frequently omitted or not fully taken into account as it requires inefcient measurements. To detect the angular and radial conditions of the radiation feld, we proposed a novel evaluation method using Lie derivative analysis against radiochromic flm dosimetry in this study. This method directly compared the detected dose distributions with the calculations, obtained the discrepancy of the fow feld from the mathematical characteristic of Lie derivative, resulted in a detection of the radial and angular discrepancies that have not been handled by conventional gamma analysis.
