최근 컴퓨터를 이용한 시각 분야가 발전하면서 인간과 관계된 연구가 중요시 되어, 사람과 컴퓨터의 인터페이스에 대한 새로운 시도들이 다양하게 이루어지고 있다. 특히 얼굴 형상 모델링과 얼굴 표정변화를 애니메이션 화하는 방법에 대한 연구가 활발히 수행되고 있으며, 그 용도가 매우 다양하고, 적용 범위도 증가하고 있다. 본 논문에서는 한국인의 얼굴특성에 맞는 표준적인 일반모델을 생성하고, 실제 사진과 같이 개개인의 특성에 따라 정확한 형상을 유지할 수 있는 3차원 형상 모델을 제작한다. 그리고 자연스러운 얼굴 표정 생성을 위하여, 근육모델 기반의 얼굴표정 생성 시스템을 개발하여, 자연스럽고 실제감 있는 얼굴애니메이션이 이루어질 수 있도록 하였다.

Stereoscopic 3D animation contents are in the rise as a key part of contents market. Major animation studios are planning to produce 3D animations in a stereoscopic process. This study aims at understanding the visual textuality of 3D animation contents at its early stage. To understand 3D animation, , are analyzed. Stereoscopic 3D animations are exploring the new visual aesthetics using the specific storytelling, sequence ordering, camera working, shot size and camera angles etc. Based on these visual textualities, stereoscopic 3D animations are constructing telepresence, multi-senses of individual spectators. Stereoscopic 3D animations have formed their own aesthetics and cultural meanings in the digital age.

This study explored aspect and intermedial characteristics at the beginning of the abstract animation and the semiotic meaning of abstract animation. Abstract animation was formed by arbangaridist, and there was an abstract painting on its foundations. The abstract painting belong to 'symbol sign' and do not represent specific objects. The abstract animation loses its object and we knew that the abstract animation itself to be object. Abstract animation is a category of ' media combination ' that combines abstract painting and music with intermediality. Abstract animation began based on abstract paintings, but was combined with music and time, and evolved into new media. The abstract animation was started by avant-gardists such as Walter Ruttman, Viking Eggeling and Hans Richter. They set aside their own time of abstract animation based on music. Oskar Fischinger was influenced by Walter Ruttman who completed abstract animation and went to America to continue his work. After Oskar Fischinger, John Whitney continued his genealogy using computer graphics. The abstract animation was faithful to the underlying meaning of the medium in the absence of the object for representation.

Art has evolved into remarkable changes in its art form maintaining a close link with the contemporary scientific technologies that gave birth to new tools of expression in each era. Animation is an art form in an inextricable connection with technological aspects because it was spawned by the technical background like movies. In this regard, animation is often viewed very strongly by technical advancements in terms of an aesthetic approach. John Whitney Sr., one of the pioneers in computer graphics arts, turned his attention to the new technology called computer graphics as a means to visualize images and movement. The advent of a new medium had a strong influence not only on tools and means for novel expression but also on the gradual shift in thinking about arts and even the audiences' taste. In the 1980s, animation was combined with computer technology and the rapid progress of computer graphic technology opened up the era of new visual aesthetics, Today, the development of digital technology presents a different dimension of realism, either advocating hyperrealism by digital actors or presenting new illusionism by classic cartoon characters emphasized in a distortion or metamorphosis from a real life in order to consolidate animation realism. Based on the two perspectives mentioned above, this study can identify methods of digital character appropriation focused on the works of the ACM SIGGRAPH Asia and find how the relationship between art and technology has changed the digital realism and evolved the digital character as the digital technology has developed.

The study proposes an exploratory analysis on the success of animation films in Korea industry. It identifies animation films that have been successful in the Korean film industry during 2004-2013 period and explores (1) how the number of screens allocated to the films have been changed; (2) what are the major factors that influence the success of the films; (3) what are the differences between Japan and the US animation in terms of plots and genres; and (4) how the characteristics of the US animations are related to the success of the US market, the global market, and Korean market. Analyses show that the number of screens allocated to the animation films has been consistently increased due to the vertical integration of Korean film industry; and the (FTA) period, months in year (summer and winter break months for middle and high school students), and the number of screens allocated to the films were the major factors influencing the financial success of animations. It also finds that specific characteristics embedded in its own cultural trait were shown in the plots and genres in the animations. Lastly the study also finds that specific set of characteristics extracted from IMDB site influence certain markets. Budgets and actor's power were found to influence the success in the US market while period (pre-FTA, FTA, post-FTA) only influence the success in Korean market. The study points out that the success of the US and Japan animations in Korean film industry are due to the historicity of animation cultures which are not found in Korean animation industry.

코로나19 이후 화상회의 빈도가 높아지면서 줌 피로라는 신조어가 등장할 만큼 상대방을 가까이 마주하며 회의를 진행하는 것이 사람들의 피로도를 상승시키고 있다. 본 논문에서는 얼굴 합성과 이미지 애니메이션을 이용한 아바타를 통해 사용자가 화상회의에 참가할 수 있는 시스템을 제안한다. 사용자와 닮은 개성 있는 캐릭터는 실시간으로 사용자의 표정 및 움직임을 반영하여 화상회의에 적용될 수 있고 채팅과 커뮤니티에서 캐릭터의 이모티콘으로 감정을 표현할 수 있다.

We present a method for creating realistic 2D stick figure animations easily and rapidly using captured motion data. Stick figure animations are typically created by drawing a single pose for each frame manually for the entire time interval. In contrast, our method allows the user to summarize an action (e.g. kick, jump) for an extended period of time into a single image in which one or more action lines are drawn over a stick figure to represent the moving directions of body parts. In order to synthesize a series of time-varying poses automatically from the given image, our system first builds a deformable character model that can make arbitrary deformations of the user's stick figure drawing in 2D plane. Then, the system searches for an optimal motion segment that best fits the given pose and action lines from pre-recorded motion database. Deforming the character model to imitate the retrieved motion segment produces the final stick figure animation. We demonstrate the usefulness of our method in creating interesting stick figure animations with little effort through experiments using a variety of stick figure styles and captured motion data.

Realistic facial animation research field which communicates with human and computer using face has increased recently. The human face is the part of the body we use to recognize individuals and the important communication channel that understand the inner states like emotion. To provide the intelligent interface. computer facial animation looks like human in talking and expressing himself. Facial modeling and animation research is focused on realistic facial animation recently. In this article, we suggest the method of facial modeling and animation for realistic facial synthesis. We can make a 3D facial model for arbitrary face by using generic facial model. For more correct and real face, we make the Korean Generic Facial Model. We can also manipulate facial synthesis based on the physical characteristics of real facial muscle and skin. Many application will be developed such as teleconferencing, education, movies etc.
