The purpose of this paper is to propose a new methodology that approaches the problem of art analysis by combining AI, especially the recent technology of GAN (Generative adversarial network), and psychological experiments. Furthermore, using the methodology, we tackled the task of clarifying the differences and similarities in impressions of Eastern/Western figurative/abstract art and the position of media art produced by one of the authors, Naoko Tosa. Several image sets have been prepared; a flower photo set (A), an art image set of Impressionism paintings (B1), an art image set of Western abstract paintings (B2), an art image set of Chinese representational paintings (B3), and an art image set of abstract images created by Naoko Tosa, one of the authors (B4). The transformation from A to each of B was carried out using GAN and thus four image sets, for which their original artist and art genres were anonymized, were obtained. Using the obtained four image sets, a psychological experiment was carried out by asking subjects consisting of 23 students to fill in questionnaires. By analyzing the obtained questionnaires, we have found the following. Abstract paintings and representational paintings are judged to be different. Representational paintings in the West and East were judged to be similar. Abstract images by Naoko were judged as similar to Western abstract images. These results show that AI could be used as an analysis tool to investigate differences among artworks and art genres without a bias caused by the prejudice most subjects have toward specific artists, artworks, or art genres.

Researchers assume that the bodies of several Tara statues may have been molded from the same template. Therefore, researchers are eager to study the shape similarities between the Tara statues. Motivated by the archaeologist's requirements, this study presents an efficient approach to evaluate shape similarities between point clouds of two different Tara statues right-arm models. The evaluation approach consists of two main stages. The first is the reconstruction of individual body parts without decoration using a B-spline surface approximation technique. In previous reconstruction process, the surrounding surface selection parameter was manually specified. If the manually applied parameter is inadequate, it reduces the accuracy of the surface approximation and hole-filling, resulting in reduced accuracy of the evaluation result. Therefore, in this study, the surrounding surface selection parameter is automatically determined based on the Golden-section-search algorithm. The second stage evaluates the shape similarities between two different point clouds. The evaluation method considers a simple point-to-surface distance metric method with overlapping-surface detection and when compared with generic point-to-point distance metric method, the evaluation results proved that the proposed methodology was reliable and effective for this application. The approximation accuracy affects the evaluation result when the reconstruction method fills the gap by adding new points through the approximated surface. Therefore, in this study, the shape similarities were investigated between the two arm models with holes, immediately after separating the decoration parts.

Deformation plays an essential role in expressing various properties of materials. In recent years, as video works have become increasingly high-definition, higher-definition deformation has also come to be required. One of the most common deformation simulation methods is mesh-based. However, due to the large amount of computation time, real-time applications cannot render detailed deformation such as the rippling of the object's surface. On the other hand, an approach using displacement mapping is known as a deformation simulation method that realizes real-time performance. However, this method is designed to be applied to a two-dimensional plane, and hence, when applied to an object surface which has a nonlinear relationship between the texture space and the real space, the deformation will be distorted by Jacobian to translate the coordinates. In this paper, we propose a novel method to simulate Jacobian-free deformation of arbitrary genus-0 surfaces by displacement mapping, which uses the real space coordinates to eliminate the distortion between the texture space and the real space.

The purpose of this study is to examine how broadcasting stations try to "survive" by using their own "people, things, money, and information. The author has been involved in program production for 36 years at TV Tokyo. Through detailed data analysis of the tacit knowledge and specialized knowledge he has cultivated through his experience, he reveals the current status of TV Tokyo's strategy to turn its "weak points" and "negative" aspects into "positive" ones. There is a reason for focusing on the "weak points" and "negative" aspects in this study. We believe that new "ideas" exist in the strategies of the weak to overcome their negative aspects. This paper is appropriate for the current era of intensifying paradigm shifts in the broadcasting industry toward the distribution business, and is the first study of the theme of how broadcasting stations should manage program content as a business from the two domains of tacit knowledge and data analysis, or so-called art and science. We believe that this is a useful topic that should be shared within the society. In the end, we would like to make a proposal for better operation of program content at broadcasting stations, highlighting its harmful effects and problems, and foreseeing the future of broadcasting stations.

We investigate the impressions of two walking styles (good and poor posture). An optical motion capture system is used to measure the two walking styles, which are performed by a walking instructor. Furthermore, a subjective evaluation experiment is conducted to examine the impressions of the two walking styles. The results suggest that the impression of leg motions, in addition to the impression of the trunk posture, may influence the impressions of walking motion. Walking with good posture, in which a person keeps the trunk upright and clearly flexes and extends the knee and ankle joints, gives the impressions of "beautiful", "elegant", "attractive", and "healthy".
