This paper describes a new method for superimposing virtual objects with correct shadings onto an image of a real scene. Unlike the previously proposed methods, our method can measure a radiance distribution of a real scene automatically and use it for superimposing virtual objects appropriately onto a real scene. First, a geometric model of the scene is constructed from a pair of omni-directio...

We discuss the scaling behavior of the self-organized critical forest-fire model on large length scales. As indicated in earlier publications, the forest-fire model does not show conventional critical scaling, but has two qualitatively different types of fires that superimpose to give the effective exponents typically measured in simulations. We show that this explains not only why the exponent...

We show that a recently discussed apparatus for aberration-canceled interferometry may be modified to perform correlated-photon imaging in the so-called “ghost” imaging configuration. For objects in the vicinity of a particular plane, the images are free of object-induced phase distortions. This apparatus has the distinctive feature that it may be used to superimpose images of two objects in a ...

This paper proposes a new technique to support making 3D character animations with DID (Dinosaur or Direct Input Device). The key idea is to superimpose the image of a CG model on a physical armature using video see-through HeadMounted Display (HMD). Using this technique, animators can easily recreate the posture of the physical armature. In addition, the system shows candidates of postures for...

We take for granted a world in which geographical borders lines separating physical spaces are of primary importance in determining legal rights and responsibilities. Territorial borders, generally speaking, delineate areas within which different sets of legal rules apply. There has until now been a general correspondence between borders drawn in physical space (between nation states or other p...

We consider the following communications system: A mobile cellular telephone company would like to serve K users simultaneously. Each user (transmitter) transmits data to the company’s base station (receiver) in the form of bits (0’s and 1’s). By modulating electromagnetic waves of different frequencies, each user’s data can be transmitted on a fixed set of “frequency slots” approved the govern...

Apply the separation principle of the physical contradictions in TRIZ into the simulation of forest fire smoke; propose a forest fire smoke recognition algorithm based on gray bit-plane. To get eight images of moving smoke, the separation process on smoke moving images is necessary; use high-diagram image (the 7th,the 8th image) to extract contours, and extract the contour of the remaining imag...

This demonstration describes a new high dynamic range (HDR) display system that generates a physical 3D HDR image without using stereoscopic methods. To boost contrast beyond that obtained using either a hardcopy or a projector, we employ a multiprojection system to superimpose images onto a textured solid hardcopy that is output by a 3D printer or a rapid prototyping machine. The physical cont...

If visualization is more effective when accompanied by narration, why not superimpose visualization on narration? This might result in better transfer of learning. We will present a general framework for such superimposed visualization, called overlay visualization. The objectives for the design of our framework are 1) to separate the application from the visualization; and 2) to separate the s...
