This paper describes the performance of an image capture simulator. The general model underlying the simulator assumes that a) the image capture device contains multiple classes of sensors with different spectral sensitivities and b) that each sensor responds linearly to light intensity over most of its operating range. We place no restrictions on the number of sensor classes, their spectral se...

Refer to Figure 1. A monotone matching is a set of n segments, each the portion of a unique pseudoline, and each spanning a unique slab, such that the left endpoint of each segment is above the right endpoint of the segment in the previous slab. In addition, the point on the first vertical line is below the left endpoint of the first segment, and the point on the last vertical line is above the...

We propose to measure the 3D arrangement of multiple portable information devices operated by a single user from his/her facial images captured by the cameras installed on those devices. Since it becomes quite usual for us to use multiple information devices at the same time, previous works have proposed various styles of cooperation among the devices for data transmission and so on. Other prev...

This thesis explores two specific topics of discrete geometry, the multitriangulations and the polytopal realizations of products, whose connection is the problem of finding polytopal realizations of a given combinatorial structure. A k-triangulation is a maximal set of chords of the convex n-gon such that no k+1 of them mutually cross. We propose a combinatorial and geometric study of multitri...

We propose to estimate the position of each student in a classroom by observing the classroom with a camera attached on the notebook or tablet PC of the lecturer. The position of each student in the classroom is useful to keep observing his/her learning behavior as well as taking attendance, continuously during the lecture. Although there are many previous works on estimating positions of human...

In this paper we studied the geometry of a three-dimensional tableau from a single realist painting – Scott Fraser’s Three way vanitas (2006). The tableau contains a carefully chosen complex arrangement of objects including a moth, egg, cup, and strand of string, glass of water, bone, and hand mirror. Each of the three plane mirrors presents a different view of the tableau from a virtual camera...

"Visual Field Record System" is aim to support participant's behavior analysis in distance education using interactive video teleconference system. An examination of the eye camera position is important to use the system effectively. Because the camera's angle and zoom rate is considered participant's behavior in this system. Actually, there are some problems that it originates in the camera po...

This paper presents a 0.25 scale quasi-three-dimensional hydraulic model experiment of transient fluid flow phenomena during continuous casting steel. The relationship between the process and jump phenomenon is established. in mold divided into four stages (I–IV) from beginning to end casting. filling involves I–II investigated by high-speed camera. part cast start. In this paper, behavior vari...

This paper presents a method of stereoscopic panoramic video generation including techniques for panorama projection, stitching and calibration for various depth planes. The methods described can be used on video sequences captured by an arrangement of multiple pairs of cameras or multiple stereoscopic cameras mounted on a regular polygonal shaped camera rig. Algorithms can also be used in comb...
