CONFERENCE PROCEEDINGS FREE ACCESSWe propose a new approach to easily 3D geometric models. A technique called interactive evolutionary computation (IEC) is introduced to efficiently support a process of user's new shape creation in an early design stage. The proposed IEC-based design system generates aesthetically pleasing shapes through the simulation of evolutionary processes. The users only need to subjectively specify the degree of "likes or dislikes"for shapes generated by the system, and the system creates more preferred models for them. The system allows even beginners with little knowledge and experiences of the 3D modeling to acquire innovative shapes. It also provides skilled experts with an advanced geometric modeling interface based on the implicit surface method. The experts can directly modify the internal parameters of the 3D models to make them more elaborate ones. The result of a preliminary experiment is presented to show the potential of the proposed modeling method.View full abstractDownload PDF (1415K) -

CONFERENCE PROCEEDINGS FREE ACCESSEfficient representations of 3-D object shape and its texture data have attracted wide attention for transmission of computer graphics data and for interactive design in manufacturing. Polygonal mesh data which consist of connectivity information, geometry data and texture data are often used for representing 3-D object in many applications. In this paper we propose a compression method of polygonal mesh data by structuring its geometry and textyure data on triangular lattice with extended node. The structured geometry and texture data are compressed using 2-D image coding method. Experimental results applying new method to polygonal mesh data show the proposed method performs efficiently.View full abstractDownload PDF (1103K) -

CONFERENCE PROCEEDINGS FREE ACCESS3D visualization of the structural change of the protein is helpful for comprehension of the characteristrics of the protein. This paper proposes a new method applying the multiple root tree data structure to molecular modeling. With computer graphics techniques, spatial structurally evolution of the protein can be represented on the computer. this method is effective to illustrate a protein behavior under different spatial structure and to compress the data.View full abstractDownload PDF (1048K) -

CONFERENCE PROCEEDINGS FREE ACCESSWe are now developing a problem solving and knowledge acquistion system based on co-reference between drill texts and dialogue with a teacher, focusing on first grade mathematics. The system offers multiple input and output channels such as natural language, gestures, and graphics. This paper discusses a method of generating gestures in cooperation with utterance generation. A gesture in this case means pointing of objects on the drill text or drawing pictures. It is represented by the movement of a pen, and is displayed as 3-D graphical data. We present Gesture Frame for a meaning description of gesture. First, the architecture of our system is summarized. Then the pointer sequence and gesture frame are defined in order to describe the structure and meaning of gesture. Lastly, results of the simulation are shown.View full abstractDownload PDF (903K) -

CONFERENCE PROCEEDINGS FREE ACCESSWith the digitalization of broadcasting, the mechanism that supplies good contents voluminously is required. When remaking the new contents from the video and audio data, index information is frequently used. But the indexing impacts the work quantity in a program production process. In this paper, we propose the event detector system that detects index addition timing in a real time by using speech recognition technology for the purpose of the laboe-saving of the indexing process. Furthermore, we propose the automatic contents authoring system that uses the index information.View full abstractDownload PDF (918K) -

CONFERENCE PROCEEDINGS FREE ACCESSMethods for tracking moving objects in a motion picture have been the subject of much research. These methods include those used in the automatic video recording of lectures where it is necessary to recognize the movement of the lecturer, the "lecture facilitator, " and to control recording cameras in accordance with that movement. This paper reports on the results of experiments performed to compare various moving-object-tracking methods with the aim of establishing a lecturer-tracking method as a basis for automatic video recording of lecures in a lecture archive system. In the experiments, a number of techniques were first selected with respect to difference ectraction, types of difference-picture information, types of extracted rectangles, and picture size. Combinations of these techniques were then applied to the actual tracking of moving objects and compared from the viewpoints of accuracy and speed.View full abstractDownload PDF (1154K) -

CONFERENCE PROCEEDINGS FREE ACCESSThe ISDB-T system has a flexibility for providing various digital broadcast services, because some transmission layer parameters, such as the modulation scheme, coding rate and time-interleaving length, can be adopted each OFDM segment. However, a procedure to change the transmission parameters without signal discontinuation has not been made clear yet. In this paper, a procedure for changing transmission layer parameters is proposed, and the amount of damaged data in the transition period is shown.View full abstractDownload PDF (988K) -
