From prehistoric paintings on cave walls to modern flat panel displays, plane media have always been a versatile means for showing projected images of three-dimensional objects. If dimensional analogy is correct, one may suppose that stereoscopic displays could be used to represent the projection into three dimensions of objects from a four-dimensional world. Adding one more dimension will bring various benefits. For instance, it is well known that the calculation of total circuit impedance can be simplified by using complex number representation. However, it is generally not easy for us, living in three-dimensional space, to use our intuitive imagination to understand the four-dimensional world. A story about a square that lives in a two-dimensional world, which was narrated by Edwin Abbott Abbott in the book "Flatland," is almost the only glimpse for non-mathematicians of a shift into higher dimensions. In 1982, the author attempted to graph complex functions by superimposing graphs of the functions that map a real part of a complex number to a complex number. By making the most of today's advances in stereoscopic systems, we can understand the projection of a one-dimensional complex manifold more intuitively. The purpose of this paper is to introduce some studies relating to the visualization of a one-dimensional complex manifold, and to discuss analytical approaches and methodologies. Using recent stereoscopic systems to gain another view of classical mathematics may contribute to educational improvement.

The story goes to like a rainbow. The color has some spiritual aspects. Red indicates a face of emotion, orange of love, overflowing yellow, green of adults, blue of soft head, talkative indigo, and purple of independence. The casts of the film are only women. It is the director's attempt to express the character, "feniale," instead of explaining the specific meaning of the "color" as she shots women for reflecting by herself. It is also the behavior like painting over on the photosensitive film that has been burned. This film directs the sense of turning a page of a fashion magazine when the scene of the color has been changed. The color has never been combined. This film is 16mm. The theme is that rainbow has each character and different senses. It is composed by seven chapters.

Object images created from photographs are useful as the source material of image compositing. However it is difficult to create manually a huge amount of object images. In this paper, we proposed a semi-automated object extraction system. This system utilizes the users' operation of their performing content-based image retrieval by query image. The proposed system utilizes both the query and the user-selected result images. The system estimates pixels of object region and that of background region from this pair of images. Using these pixels, object image is automatically extracted using a conventional image segmentation method. With our system, object images are created whenever users perform content-based image retrieval.

The computer-generated holograms (CGH) can reproduce virtual objects as complete 3D image in real space. In our previous research, we could not create point cloud that depicts the caustics and Fresnel reflection at incidents for clear objects, because the radiosity method is used. In this report, we adopt progressive photon mapping (PPM) in a generating process of point cloud. As a result, we realize to generate point cloud for more photo realistic CGH. Then, we create CGH from the realistic point cloud.

The Hologram is known that can reconstruct three-dimensional images perfectly. The Computer-Generated Image Hologram (CGIH) is the hologram that is calculated interference phenomenon by computer, and reconstructed image placed near the hologram plane. In our previous study, because of improvement of the output device, it has been possible to output high resolution and refinement CGIH. However, the distortion of the reconstructed image caused by the approximated calculation for high-speed computing has become a serious problem. In previous report, we abolish approximate calculation by fast computation using the GPU, and get the appropriate reconstructed image. In this paper, we improved the Image quality of near the hologram-plane and calculation speed by using optimized the point-source data and made full-color CGIH with proposed method.

The recent spread of low-cost, high-performance digital cameras and smartphones allows us to share a large-scale imagery data on the Web. However, most of such images were taken subjectively in terms of composition and chosen targets. This article presents an ambient visualization system which makes up for the semi-structured properties of still images so that the users can comprehend the surrounding environment as well as photographed objects in an objective manner. To that end, the proposed system organizes a collection of input images is into a tree-of-graph structure called abstraction hierarchy, and provides the users with two specific types of view transformation, i.e., vertical view scaling and horizontal view scrolling.

Protein is the major component of the organism. It has a unique typical three-dimensional structure determined by the sequence of, amino acids. A hole (pocket) on the surface of a protein is known to be the best target for a drug to react. We started analyzing how "druggability" of proteins related to the locations amino acids in a pocket. For a starter of this study, this paper presents a visualization tool for distance distribution analysis between two types of amino acids in a pocket. When protein surface is provided by triangular meshes, this tool first identifies a pocket from the protein surface, specifies the deepest position of the pockets, and calculates distances between atoms of an amino acid and the deepest positions of the pocket. This tool then visualizes the distribution of the distances by scatterplots. This paper proposes the a biological interpretation of the visualization results.

The proposal in this study is to design a tone creation supporting system based on KANSEI information. The recent computer innovation brought many things that used to be difficult to realize. However, it is hard for inexperienced persons to make a tone from the present Desk Top Music Software. With in a technical term, it is hard for them to imagine what kind of tone to be heard. If technical terms are transposed to KANSEI words, we will be able to imagine a tone easier than now. This study is a challenge to build the system based on the KANSEI information from which everyone can make a tone more freely. This study uses the wavelet transform to analyze sounds, the factor analysis which used the maximum likelihood estimate method to analyze the subjectivity evaluation value acquired by the semantic differential method.
