To create a more realistic soccer game derived from TV images, we are developing an image synthesis system that generates 3D image sequence from TV images. We propose the method for the team and the pose recognition of players in TV images. The representation includes camera calibration method, team recognition method and pose recognition method. To find the location of a player on the field, a field model is constructed and a player's field position is transformed by 4-feature points. To recognize the team information of players, we compute RGB mean values and standard deviations of a player in TV images. Finally, to recognize pose of a player, this system computes the velocity and the ratio of player(height/width). Experimental results are included to evaluate the performance of the team and the pose recognition.

This paper introduces a new motion-synthesis technique for animating multiple characters. At a high level, we introduce a hub-sub-control-point scheme that automatically generates many different spline curves from a user scribble. Then, each spline curve becomes a trajectory along which a 3D character moves. Based on the given curves, our algorithm synthesizes motions using a cyclic motion. In this process, space-time warp curves, which are time-warp curves, are embedded in the 3D environment to control the speed of the motions. Since the space-time warp curve represents a trajectory over the time domain, it enables us to verify whether the trajectory causes any collisions between characters by simply checking whether two space-time warp curves intersect. In addition, it is possible to edit space-time warp curves at run time to change the speed of the characters. We use several experiments to demonstrate that the proposed algorithm can efficiently synthesize a group of character motions. Our method creates collision-avoiding trajectories ten times faster than those created manually.

Based on Maslow's hierarchy of needs theory, this research only employs whether to meet consumer needs as a measure, and focuses on the Collaboration Series between Uniqlo and KAWS to discuss the influence of the collaboration between fashion brands and artists on consumer needs. What's more, this paper also proposes whether the collaboration with artists as brands can meet the higher needs of consumers and influence new consumer groups. Finally, it is concluded that the collaboration between fashion brands and artists plays an active role in meeting the higher needs of consumers and can expand new consumer groups, which will provide reference and theoretical basis for enterprises to conduct collaboration with art, incorporate the needs of consumers into the scope of planning, and consider the collaboration with artists more comprehensively.

The paper is devoted to problem of spline approximation. A new method of nodes location for curves and surfaces computer construction in multidimensional spaces by means of B-splines is presented. The criteria are which links a square-mean error caused by high frequency spline distortions and approximation intervals is determined and necessary theorem is proved. In this method use a theory of entire multidimensional spectra and may be extended for the spaces of three, four and more variables. Future work: application area such as digital contents like animation, game graphic.

This paper introduces the development and current prosperity of the branch discipline of visual anthropology and describes the status and current situation of modern visual anthropology and analyzes the rationality that the achievements of visual anthropology is viewed as texts and enjoy the same achievements, making it more basis and scientific in the selection of visual anthropology in subsequent research. This article comprehensively uses Delphi method and analytic hierarchy process to construct an evaluation system of visual anthropology, as well as put forward the basic principles of screening films using this evaluation system in subsequent studies and a simple outlook for future expansion.

Through the development of the medium, Sigmund Freud's uncanny element in the Cinemagraphic technique of digital image is analyzed, and the research problem presented through the case and literature data is interpreted. Look for an Uncanned element as seen from. Interpret the theories found in art paintings and human philosophical perspectives through examples in the overlapping cinema graphs of photographs and videos that we have looked at unfamiliarity. It interprets the double surreal image of Cinemagraph through unfamiliar gaze and evaluates new horizon with digital photograph.

In this paper, the system is implemented in four ways , For those who want to learn Chinese characters using the internet, and To make the learning more interesting and entertaining. Four different learning methods have been provided , using the transition process of Chinese characters, games, animations, and an illustration of the relationships between Chinese Characters and korean letters. The subjects of the evaluation were freshmen polled about the Chinese character learning system. The evaluation methods are : the validity of the research content is evaluated using the Cronbach's coefficient alpha and the performance of the system is evaluated by F-type of Analysis of variance.

As flash technology is a widely used in Web pages, it tends to load a S/W flash player in mobile phones and PDAs to play flash contents on diverse H/W platforms currently. In this paper, we design and implement a linux-based standalone flash player which can be used in various fields like animation, game and advertizing. We also implement an web-based manager which user can effectively manage flash players anywhere.

A new cultivation diary system based on environment sensor data and Web 2.0 with Flex is suggested, to improve the previous system using the subjective data of cultivators. The proposed system is designed by applying an object-oriented model called mini-architecture, in order to enhance the reliability of software as well as promote stability to overall system design. The environment sensor data such as temperature and humidity are used to develop the new reliable diary. Also, an active interface based on Web 2.0 and Android as the user GUI are implemented to maximize the convenience while recording the cultivation diary. The result of the performance evaluation shows that the data from sensors has 99.1% of correlation with that of analogue.
