    In recent years, 3-dimensional (3D) maps are used for movies, games and so on, with the help of powerful computers. It takes a lot of time and load to build all buildings data, which construct 3D maps, by hand. The aim of this research is to build semi-automatically 3D maps from 2-dimensional (2D) maps, aerial photographs, and altitude data. The vertex data of buildings and roads are extracted from 2D maps, and altitude data are added, which data are obtained from numerical map 50m of Japan map center. Since the target area belongs to the second sort low layer exclusive residential district, the heights of the buildings are defined at random between 6 and 8m. Also, the colors and forms of roofs are extracted from aerial photographs. The created 3D map can be used for car navigation, landscape simulation, and so forth.

    This paper describes a new blending method of human motion from some fundamental motion models previously obtained by motion capture system. In motion blending, there are some researches which consider only joint positions and angles of human body ; however, in this paper, the joint speed and the acceleration are considered in addition to the position and the angle. Some fundamental motions are captured by motion capture system and a blended motion is generated by considering, weights as the masses at some parts of human body. Then, the generated motion is revised with dynamics and finally more exact motion is generated. This method enables us to generate arbitrary composite motions from some fundamental motion models.

    This paper describes the architecture and the evaluation of 3D modeling system, which has an intuitive user-interface by using gesture motion. This system has only fundamental functions necessary for 3D modeling. Among user-interface using human gesture, data gloves are the best ; however, haptic devices, which have force feedback, is very expensive so that a data glove that does not have force feedback is adapted for the system. As a communication mean in place of force feedback, visual feedback is used in this system. In order to place model objects at the exact position by hand, this system uses discrete movement method of model objects in the virtual space. It has been found that the visual feedback and the discrete movement method are useful for 3D modeling by using this system.

    Holography is a technique that enables us to reconstruct 3D images in the space. Several reconstructing techniques using photorefractive crystals or systems with lenses have been studied. However, they have some drawbacks such that the size of the reconstructed images tends to be small, and the area of a view is to be limited by the lenses. Here we present a new reconstructing method with the use of scattering of particles. The scattered particles play a role just as a screen. It enables us to observe relatively large 3D images easily.

    Noise was added to digital prints to improve gradation and texture of subject. Changing level of noise, type of images, and area, where noise is given, samples were made and subjectively evaluated. Under some conditions addition of noise resulted in increase of scores. It was not achieved to estimate optimum noise level for a picture from the Mahalanobis-distance, but it realized to distinguish pictures which are improved from ones which become worse by adding noise.

    The painting has a long history and a peculiar aesthetic expression has been pursued. We have studied paintings aiming to obtain an impressive digital print by using their expresson technology. In this study it is attempted to obtain digital printings with high chroma by using the color mixing method by Seurat who was one of the Neo-Impressionist and established the pointillism. He did not mix colors on his palette but in our eyes by putting colors which want to be mixed side by side. Here the colors which Seurat used were analyzed, and the combination of basic colors and their complementarry colors and size of points were investigated.

    The aim of this paper is automatic generation of painting-style images from photographic images. Several work has been done for modeling painting tools and materials so that strokes of brushes can be automatically generated from input images. However, when strokes arc overlapped, colors of overlapped regions are decided without considering gradations between different colors. In this paper, therefore, we propose a graze model for deciding colors of overlapped strokes by considering optical transmission characteristic of paints and human vision properties.

    It is necessary to properly quantize in limited number of color to output full color image with device including the printer, etc. In previous, many method including error diffusion have been proposed to display the high quality color image in limited number of color. However, these method is problem that issue regulary striped pattern in the small change of the tone area and do not represent properly halftone in the large change of the tone area. In this article ,we proposed the quantization of the color image using simulated annealing of one of the combinational optimization to solve this problem. As a result, we obtained to the high quality of the quantization image with color image or monochromatic image.

    Some Japanese historical materials, such as folding screens or scrolls, are extremely large but depict very fine objects. A super high-definition free viewing system for these materials has been developed to solve the problem that the full details or entire figures cannot be observed because of lighting limitation or their shape. The system is capable of displaying large images, allowing the image to be scaled for viewing from any location at an appropriate size by magnification ratio of over 100 times. The effectiveness of the system comes from intuitive user interface and smooth, gradual magnification or movement of images.

    We propose a system for a media art work named "A soul of a trail", which generates tracinglines vurtually in the air corresponding to motions of a handy input device. When an experience person draws lines in the air with a direction rod, the system extracts a designated color and outputs correspoinding pixels on a CRT monitor. After a short duration, the virtually generated trails begin drifting and transforming on the screen, and then vanishes out. Through the experience with this system, a person can have and realize a feeling that he draws an object in an 3D-space canvas.

    This interactive art projects oneself on the monitor, and controls the image with the participant's hands. Once a participant moves the arms like a wall lizard (Yamori) or a rock climber, the participant virtually climbs the background image in the monitor. Fusing optical feedback from physical intuitive control, with subjectivity according to an image taking in one's own, a virtual reality is actualized. The motion of the arms is obtained by extracting almost uniform color regions in the screen corresponding to the colored gloves worn by the participant.

    Our intention is to make motion image of the oil painting with keeping the charm of the oil painting by Hara. But there may be the problems of the loss of the charm of the oil painting with this conversion. It is the "loss of the aura", as in the "Art in the Copy Age" by Benjamin. On the other hand it is true that the loss of the charm may not be 100%. We may keep 40〜50% of charm by our effort and technology. We expect you to see how we kept the charm of the oil painting. The music (66sec) is composed by Sakisaka.
