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. ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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, ...
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 ...
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 ...

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. ...
The number of computer controlled vehicles throughout the world is rising at a staggering speed. Even though this enhances the driving experience, it opens a new security hole in the automotive industry. To alleviate this ...
We focus on a uniform partition problem in a population protocol model. The uniform partition problem aims to divide a population into k groups of the same size, where k is a given positive integer. In the case of k=2 ...
This paper proposes a voltage stabilization scheme for feeding constant voltage to receiver in single-frequency
two-stream contactless power transmission under the presence of cross coupling among couplers. We have ...
