  • Kubo, Hiroyuki; Tokoi, Kohe; Mukaigawa, Yasuhiro (Association for Computing Machinery, 2015-07)
    To synthesize realistic translucent materials in computer graphics, it is necessary to simulate the effect of subsurface scattering. In previous works, several methods are proposed for rendering such materials in real-time. ...
  • Mihara, Hajime; Funatomi, Takuya; Tanaka, Kenichiro; Kubo, Hiroyuki; Mukaigawa, Yasuhiro; Nagahara, Hajime (IEEE, 2016-05-16)
    In this paper, we describe a supervised four-dimensional (4D) light field segmentation method that uses a graph-cut algorithm. Since 4D light field data has implicit depth information and contains redundancy, it differs ...
  • Kobayashi, Yoshie; Morimoto, Tetsuro; Sato, Imari; Mukaigawa, Yasuhiro; Tomono, Takao; Ikeuchi, Katsushi (IEEE, 2016-06-30)
    Reconstruction of shapes and appearances of thin film objects can be applied to many fields such as industrial inspection, biological analysis, and archaeologic research. However, it comes with many challenging issues ...
  • Tanaka, Kenichiro; Mukaigawa, Yasuhiro; Kubo, Hiroyuki; Matsushita, Yasuyuki; Yagi, Yasushi (IEEE, 2016-06-30)
    his paper presents a method for recovering shape and normal of a transparent object from a single viewpoint using a Time-of-Flight (ToF) camera. Our method is built upon the fact that the speed of light varies with the ...

    Figure 1. Overview of FIPCO. The first row shows how it was recorded. The second row presents sampled data from the three cameras and an accumulated gaze position plots over a whole sequence. The third row introduces the ...
  • Okamoto, Midori; Kubo, Hiroyuki; Mukaigawa, Yasuhiro; Ozawa, Tadahiro (IEEE, 2016-07-08)
    Acquiring scattering parameters from real objects is still a challenging work. To obtain the scattering parameters, physics-based analysis is ineffective because huge computational cost is required to simulate subsurface ...
  • Kubo, Hiroyuki; Jayasuriya, Suren; Iwaguchi, Takafumi; Funatomi, Takuya; Mukaigawa, Yasuhiro; G. Narasimhan, Srinivasa (2018-05-31)
    Separation of light transport into direct and indirect paths has enabled new visualizations of light in everyday scenes. However, indirect light itself contains a variety of components from subsurface scattering to diffuse ...
  • Tanaka, Kenichiro; Kubo, Hiroyuki; Ikeya, Nobuhiro; Funatomi, Takuya (IEEE, 2018-06-23)
    We present a novel time-resolved light transport decomposition method using thermal imaging. Because the speed of heat propagation is much slower than the speed of light propagation, transient transport of far infrared ...
  • Kushida, Takahiro; Tanaka, Kenichiro; Aoto, Takahito; Funatomi, Takuya; Mukaigawa, Yasuhiro (IEEE, 2019-03-17)
    Phase ambiguity is a major problem in the depth measurement in either time-of-flight or phase shifting. Resolving the ambiguity using a low frequency pattern sacrifices the depth precision, and using multiple frequencies ...

    Automatic colorization is a significant task especially for Anime industry. An original trace image to be colorized contains not only outlines but also boundary contour lines of shadows and highlight areas. Unfortunately, ...
  • Takatani, Tsuyoshi; Aoto, Takahito; Tanaka, Kenichiro; Funatomi, Takuya; Mukaigawa, Yasuhiro (Association for Computing Machinery, 2018-12)
    In this paper, we propose a novel pro-cam technique for reconstruction of the volumetric relectance inside an object. The key concept is use of spatio-sequentially modulated illumination to extract only the required ...
  • Fito, Herminawan; Higashino, Takeshi; Okada, Minoru (IEEE, 2020-05-22)
    This paper investigates a transmission efficiency dependent on location of a receiver for large-scale wireless power transfer (WPT) system using parallel line feeder. Many researches usually employ electromagnetic field ...
  • Kawabata, Kohei; Higashino, Takeshi; Okada, Minoru (IEEE, 2020-03-22)

  • Yonezawa, Takuya; Arai, Ismail; Akiyama, Toyokazu; Fujikawa, Kazutoshi (IEEE, 2018-03-23)
    In bus companies, it is important for an operation manager to grasp operation states of vehicles from a viewpoint of safety management and improving an operation efficiency. Currently, for allowing operation managers to ...
  • Yonezawa, Takuya; Arai, Ismail; Akiyama, Toyokazu; Fujikawa, Kazutoshi (IEEE, 2017-12-14)
    In bus companies, it is important for the operation manager to grasp operation states of the vehicle from the viewpoint of safety management and improving the operation efficiency. Currently, for allowing the operation ...
  • Nakashima, Hayato; Arai, Ismail; Fujikawa, Kazutoshi (IEEE, 2019-03-15)
    In recent years, some bus companies have raised revenue by reviewing the route plan using the number of passengers. The company has a system that can automatically counts the number of passengers on an ongoing basis. But ...
  • El-Tawab, Samy; Arai, Ismail; Salman, Ahmad; Park, B. Brian (IEEE, 2020-08-04)
    With the fast increase of wireless technology, more new applications are developed targeting smart cities. It is clear that soon-to-be, each city will be covered with wireless capabilities besides the 5G cellular technology. ...
