To acquire images of dynamic scenes from multiple points of view simultaneously, the acquisition time of vision sensors should be synchronized. Although the influences of background light and the amplitude fluctuation have been successfully eliminated, it is still necessary to distinguish the frame indexes of multiple synchronized vision sensors. In this paper, an illumination-based synchronization...
This paper presents a new lung tumor motion prediction method for tumor following radiation therapy. An essential core of the method is accurate estimation of complex fluctuation of time-variant periodical nature of lung tumor motion. Such estimation can be achieved by using a multiple time-variant seasonal autoregressive integral moving average (TVSARIMA) model in which several windows of different...
We have been working on detecting an object with an accelerometer from many moving objects in a camera view. Our previous method relied on knowledges of specific appearance of the moving objects such as colors, which limited the practical use. In this paper, in order to reduce this dependency on the knowledges of object appearance as much as possible, we apply our method to natural feature points...
