In the paper, we propose a Fourier model to represent the dynamics of a speech balloon. Using this model, we can generate various dynamic speech balloons with different styles. Experimental results have demonstrated the effectiveness of the proposed ...

Object creation is popular in AR applications. People always load a model instead of creating models by themselves because loading a model is a simple replacement of creating people's own models if they lack the drawing skill or capability to use ...

In this paper we propose to address the problem of 3D object decomposition and super resolution. We model the 3D object as a set of Riemannian manifolds and propose metric tensor and Christoffel symbols as a novel set of features for 3D object ...

Figure-ground perception is the perceptual experience by which human observers assign a contour separating two regions to one of regions. The region owning the contour is identified as figure which has definite shape and appears near to the observer ...

Rendering techniques for design evaluation and review or for visualizing large volume data often use computationally expensive ray-based methods. Due to the number of pixels and the amount of data, these methods often do not achieve interactive frame ...

Bullet-Time is a camera work to make the observer feel like transitioning from side to side by switching multiple-view images capturing an object. Simple switching operation realizes Bullet-Time effect, if the position and orientation of the cameras are ...

Chinese ink-wash painting is a unique and fascinating form of art. Revealing the drawing process of an ink-wash artwork is visually intriguing and useful for training of painting skills. Recording the sequences of strokes by camera during the creation ...

2D to 3D conversion technologies had been researching with developing of 3D display. Existing 2D movies can be converted to 3D stereoscopic movies easily with low cost using conversion technology. Depth image-based rendering (DIBR) technique is applied ...

Three-dimensional analysis of the aurora which is an atmospheric phenomenon is significant because the shape of aurora reflects the electromagnetic relationship between the Earth and the Sun, which can influence electric equipments such as satellites. To ...

Projective properties of circular features have been widely researched as solutions for camera calibration in computer vision applications. Comparing to these researches, Chen et al. proposed a convenient method to estimate the camera position and ...

Conventional interaction researches deal with relatively small spaces with physical proximity or completely distant spaces without physical proximity. However, there is an intermediate range of them. The distance to a target for interaction is longer ...

Real world objects are not immutable and free of blemishes, but tend to change in appearance over time when exposed to their environment. As such, simulating the weathering and ageing of objects can have a significant impact on the perceived realism of ...

Chinese traditional shadow play is a shining star in the long history of the folk culture. In the work, we want to combine the new computer and multimedia technology with traditional shadow play, bring new technical elements into the traditional one, ...

A tiling of the plane is a collection of one or several types of shapes, or tiles, that cover the plane without any gaps and overlaps. Because an Escher like tiling is also very interesting for mathematical aspects, there has been many discussions as ...

Today, a number of attractive folk dances are existent in Japan. It is seen in recent years that their motion is analyzed by using motion capture (Mocap) data. On the other hand, many survey reports on Japanese folk dances have been compiled to record ...

Although much progress was made in computer graphics for water simulation, large-scale complex water simulation is still a great challenge. This may be due to that the complicated physical mechanism, such as water dynamics and the complex interactions ...

Interactions among fluids and solids are frequently observed around our daily life and simulated for various purposes. However, real-time simulation of dissolution phenomena, including erosion and liquefying, is restrictively allowed due to the ...

Color quantization is a technique for decreasing the color depth of an image. Less number of color means less space is needed for storage. Such kind of algorithms ([Heckbert 1982], [Verevka and Buchanan 1995]) have invoked a big interest in the computer ...

Transparent objects, such as diamonds, show rainbow-like colors because of the dispersion of light that passes through such objects; white light is dispersed because it comprises light waves with different wavelengths. This phenomenon has been ...

This paper proposes an image acquisition system for mobile augmented reality (AR) applications. We assume such scenarios that a passing-by user points a camera-equipped mobile device toward a digital signage displaying an advertisement movie and gets ...
