3D rendering is a critical process for a movie production, advertisement, interior simulation, medical and many other fields. Recently, several effective rendering methods have been developed for the photo-realistic image generation. With a rapid performance enhancement of graphics hardware, physically based 3D rendering algorithm can now often be approximated in real-time games. However, the high quality of global illumination, required for the image generation in the 3D animation production community is a still very expensive process. In this paper, we propose a new rendering method to create photo-realistic global illumination effect efficiently by harnessing the high power of the recent GPUs. Final gathering routines in our global illumination module are accelerated by programmable graphics hardware. We also simulate physically based light transport on a ray tracing based rendering algorithm with photon mapping effectively.

E-Learning is a modern main teaching method starting from the concept of remote education. This research is aimed for proposing cyber lecture library system and designing a cyber lecture component that becomes a basis for e-Learning system Cyber lecture library is a storage system of cyber lectures that can supply high quality data to the needed developers. Component consists of 5 categories and those are text voice, image, animation, and flash. By using this system the developers can save the necessary time and effort in education development. This system also helps students. The students can access various lecture data on a given subject and select the best fit for them.

In this study we propose to use a facial motion capture technique to track facial motions and expressions effectively by using the stereo vision module, which has two CMOS IMAGE SENSORS. In the proposed tracking algorithm, a center point tracking technique and correlation tracking technique, based on neural networks, were used. Experimental results show that the two tracking techniques using stereo vision motion capture are able to track general face expressions at a 95.6% and 99.6% success rate, for 15 frames and 30 frames, respectively. However, the tracking success rates(82.7%,99.1%) of the center point tracking technique was far higher than those(78.7%,92.7%) of the correlation tracking technique, when lips trembled.

Anticipation effect has been used as a traditional skill to enhance the dynamic motion of the traditional 2D animation. Basically, anticipation means the action of opposite direction which performs before the real action step. In this paper, we propose the perception-based video anticipation method to guide a user's visual attention to the important region. Using the image based attention map, we calculate the visual attention region and then combine this map with temporal saliency of video. We apply the anticipation effect in these saliency regions using the blur kernel. Using our method, we can generate the dynamic video motion which has attentive guidance.

Digital literacy is an important factor in the discourses on the knowledge sharing on the campus. This article analyzed the impact of digital literacy of knowledge-sharing capabilities in the university. As a result, digital literacy was found to significantly affect student knowledge-sharing capabilities in the university studied. Results show that video and animation literacy is the most influential factor and image literacy is the second-most influential factor for student knowledge-sharing. Those results can be used as a framework for developing digital literacy program.

This paper proposes an algorithm for Facial Characteristic Point(FCP) extraction. The FCP plays an important role in expression representation for face animation, avatar mimic or facial expression recognition. Conventional algorithms extract the FCP with an expensive motion capture device or by using markers, which give an inconvenience or a psychological load to experimental person. However, the proposed algorithm solves the problems by using only image processing. For the efficient FCP extraction, we analyze and improve the conventional algorithms detecting facial components, which are basis of the FCP extraction.

Today, mobile technology is developing very fast and people use internet through mobile phones. Using mobile phones, people use games, email, avatar and other services. We designed client/server modules in order to join email and avatar together. First two major server modules were designed, one of them is DB management module for avatar user information and the other is email management module. One the client side, we designed avatar image animation module and a module for showing the email contents. The purpose of the design is to reduce the performance overhead on the client side as mobile phones cannot be used as a high performance device. We propose and implement a new avatar based service using the SK-VM environment, that is different from the current avatar services.

A multi-story can be generated by the interactions of users in the interactive storytelling system. In this paper, I suggest narrative structure and corresponding Storytelling Markup Language and implement the system that processes a story presented using this language. This research will be basis of making an authoring tool for interactive storytelling. It can be used to make a story tool and story presentation tool using text, image, animation with user interaction.

Even though cartoons and narration comics were born from different origin, they have been called by names such as 'cartoons' or 'comics'. The reason can be found in the similarity of cartoons and narration comics. The similarity of cartoons and narration comics is the genre consisting of writing and drawing. Writing can be the format of expression and it can represent the story. Such story is present as a component of 'narration'. Sub genre of comics includes cartoons and narration comics. It includes animation in a broad range. In cases of narration comics and animation, it is thought that narration is present with continuity of time. However, in case of cartoon, because one or two cuts without continuity of writing are frequently expressed, it is being asked whether narration is present. It is easy to be reminded of epic or chanson de geste whenever you hear 'narration'. Since it deals with a biography of the character, we think the concept of 'narration' with temporality. However, narration provides a certain event in a broad range. Thus, cartoons presenting one event with the image may have the existence of narration, because description of multiple scenes of narrative comics can be implicitly represented in cartoons. As such implications leave a space, the empty space can be filled by active reasoning of recipients. However, nevertheless, it is very difficult to find studies as well as mentions of narration in cartoons. Thus, in this paper, we investigate the concept and structure of narration and demonstrate the presence of narration in cartoons. First of all, we looked at the narration theory in literature before studying narration in cartoons. The reason is that we thought the approach to the literary theory was required in order to investigate the basic elements, since cartoons are a collection of writing and drawing. We were focused on the prerequisites of narration presented in "story and discourse" of s. Chatman. If the prerequisites of narration are present, we can assume that the narration is present. The prerequisites are 'narration reasoning', 'screening', 'consistency', 'process statements' and 'stasis statement'. As s. Chatman described them as prerequisites of narration, he analyzed the narration structures of films and novels. In addition, we revealed that the narrations were present in cartoons as we identified how prerequisites of narration presented by Chatman were presented and expressed through "vocabulary of comics", "Timeframe" and "life in the line" described in "understanding comics" by Scott McCloud.
