Inverse halftoning is the method reconstructing the binary image with halftoning method to the continuous-tone image.Inverse halftoning has been used with device including the scanner or the copier.In previous,the method with the smoothing using the average filter or gaussian filter have been proposed.However,these method is insufficient to remove noise or to be edge enhancement.In this article,we proposed the inverse halftoning method using the emphasis of the edge and the smoothing filter of one of the smoothing filter.This method is an improvement on the gaussian filter.As a result,we obtained to the high quality of the reconstructing image.

The spectral reflection ratios for three types of watercolor pigments are measured. Two pigments are selected for mixing, then they are mixed in three levels, and the resultants are also measured. This method enables to simulate pigment mixing based on actual measurement, and also to correspond with the sensuous mixed ratio and actual one. This method also will be extended to simulate pigment mixing for an interactive painting system.

Oil painting can perform colorful expression of applying [ which is applied / which is heaped up thickly / thinly ]and piling up paints. However, probably, there are not so many people that even the man that he likes drawing a picture has drawn oil painting, since many drawing material is needed in order to draw oil painting. I considered that I wanted the man of having not drawn oil painting to know oil painting more, and started the creation of the interactive picture generation application of the oil-painting style by the impasto simple expression model which is this research.

The present paper is aiming to build a system for generating facial caricatures that looked like hand-drawn ones by introducing the following techniques; "ruling exaggeration limit", "face parts", "simulating human touch". It was suggested that addition of kansei information like brush touch results in improvement of subjective impression. Further, We're attempting to implement "automatic feature point extraction by using AAM" for automatic caricatures generation from an input face image and "outputting caricature to SVG format (vector data)" for flexibility and extendibility, and the main parts of the system were almost completed.

In this paper we first introduce how computer systems simulate intelligent processes such as learning, reasoning, and understanding symbolic information to make computer animation using varied technologies in the area of Artificial Intelligence (e.g. multi-agent, cognitive modeling, knowledge representation, etc). Then a practical paradigm is given applying to digital movie generation. Along with the improvement of computational power and human knowledge representation, it is feasible to automatically make motion picture with visual effects like computer animation and real images, and their simple composition. An example piece of animation is showed to expound how to use cinematic rules of thumb to make a scene by rule-based reasoning strategies.

Sign language is getting more important than ever because many hearing-impaired persons are working in the world. However, people are learning sign language by normal health persons or by themselves and they have to check whether or not the language they learned is correct in the real conversation with hearing-impaired persons. If there are some mistakes in the language, they cannot communicate with each other. Recently, Sign Language Skill Official Approval Association operates the certification examinations. This paper describes a sign language self-learning system for people who take the exams of level 6 and 7. The system is composed of data gloves that can get the finger angles and 3 dimensional position sensors that can detect the position of the hand. People can learn all 71 finger characters with this system by themselves.

The storage and later retrieval of observed data will play important role for various types of applications. Archiving sensing data, however, which is broadly spread over space and time, is challenging: problems include how to reduce the amount of data, how to maintain relationships between data, how to normalize the data and so on. We propose a new concept, 4D Visible Memory, whose basic idea is to store the data in a virtual space extended in the time dimension, as a solution. The prototype system, which embodies the concept in the special case of archiving data for nuclear power plant inspection, is also introduced.

This work is a cloth simulation created using OpenGL (Open Graphics Library). Although cloth is very familiar in daily life, it is very difficult to express it with reality by CG. We investigated how to express the motion and appearance like a genuine article. We paid attention especially to appearance and texture, and expressed delicate differences among various cloths by changing surface, lighting condition, thickness of cloth etc.

There are expressions of the reflection and the refraction of light by the ray tracing method and the caustics method as a technique for expressing light on the computer graphics. However, the expression of the diffraction of light is not done in these techniques. Authors expressed 3DCG of grating with an arbitrary pattern diffraction grating by simulating the Raman-Nath diffraction. This report describes CG animation created by this technique.

Texture mapping technique is very useful to make landscape simulation images using virtual reality very realistic. This paper describes an automatic texture generation method for walls and roads, which appear very often in the simulation. In order to express unevenness of the surfaces of walls and roads, some fundamental patterns are used. The simplest pattern is an image that is constructed of 2x2 pixels. As the result of some experiments, some patterns are extracted as useful one and these patterns are expanded into 3x3, 4x4 and 5x5. Also, in order to express weathered images, fractal function is used. Some generators are experimented to research which generator is useful. Finally, it has been found that this method is useful for generating some textures used for landscape simulation.

The main target of the current landscape simulation is to display some artificial or natural objects. For almost cases, even if human begins appear, they do not move or are moving just according to some fixed scenarios. Therefore, this paper proposes a method to generate a variety of human behaviors. This human behavior model is created based on psychology. In the model, some characteristics are specified to each human. Finally, the proposed method is applied to 20 students who belong to 3D virtual campus. As a result, a variety of human behaviors has been created according to individual characters.

We made 3DCG animation familiar to children. We set up characters "TIBI" and "NOPPO", in order to give sociableness to animation. "TIBI" who got "magic chalk" wanders in the castle of sand, having a wonderful experience. The "magic chalk" has the power in which a picture becomes a solid (the wanted thing turns into an actual product). The story has 3 parts and we introduce the first part (story until "TIBI" finds the "magic chalk" and wanders in the castle of sand) in this paper.

The story is "A certain Japanese salaried worker gets up late, and it is in a great hurry and is said that a story goes to a company." It thought " it is simple" as important as one element of entertainment. A sound and a title do not use it for this work, but it was made to let you those who see in it understand a story as simply as possible lucidly. I want to merely think that it is pleasant and interesting.

Say, "Living alone is begun."If it sees from others, it sees from others, it may be what it is natural and is neglected for the generation. However, for the person in question, it is a big adventure. It thought that it was real, and was mysterious and such "a start of living alone"would be used as a heart-warming work, and manufactured.
