Silhouette Animation has been recognized as a genre of animation since the very beginning of the animation history, and also Its segmental movement and Aesthetic expression has led a variety of semantic interpretations. Especially the French animation director, Michel Ocelot, recently integrated 3-dimensional digital to the silhouettes animation, and it extended the possibility of the silhouettes animation in many aspects. In his latest animation feature, , he showed how he made changes in 3-dimension by creating and evolving his own way and style of silhouette animation. Although mainstream digital animations preferably to show realistic images and motion, Michel Ocelot used very selective movement, subjective digital colors and extended space which couldn't be expressed in the way of creating traditional style of silhouette animation. This alternative slow movement and the unique aesthetics in 3-dimension emphasize the unconscious elements of color, composition, patterns, and it provides digitally enhanced images and pictorial impression. In addition, the acquisition of digital three-dimensional use of space made possible to provides the wider formative imagination to the audience. In this paper, we analyzed aesthetic characteristics of the digital silhouette animation, (2011), specially focusing on the aspects of Movement, Image, Space, which could not be found in the traditional silhouette animation. It is significant to obtain diversity of the future digital animation and its positive development. In addition, this provides opportunity to explore Michel Ocelot's new experiments and animation philosophy.

Shadow images are a representative medium and means of expression for the imagination that exists between consciousness and unconsciousness for thousands of years. Wherever light exists, people create play with their own shadows without special skills, and have made a fantasy at once. Shadow images have long been used as subjects and materials of literacy, art, philosophy, and popular culture. Especially in the field of art, people have been experimenting with visual stimulation through the uniqueness of simple silhouettes images. In the field of animation, it became to be recognized as a form of non - mainstream areas that are difficult to make. However, shadow images have been used more actively in the field of digital arts and media art. In this Environment with technologies, Various formative imaginations are being expressed more with shadow images in a new dimension. This study is to introduce and analyze these trends, the aesthetic transformations and extended methods focusing on digital silhouette animation and recent media art works using shadow images. Screen-based silhouette animation combines digital technology and new approaches that have escaped conventional methods have removed most of the elements that have been considered limitations, and these factors have become a matter of choice for the directors. Especially, in the display environment using various light sources, projection, and camera technology, shadow images were expressed with multiple-layered virtual spaces, and it becomes possible to imagine a new extended imagination. Through the computer vision, it became possible to find new gaze and spatial images and use it more flexibly. These changes have given new possibility to the use shadow images in a different way.

We propose an image-based three-dimensional shape determination system. The shape, and thus the three-dimensional coordinate information of the 3-D object, is determined solely from captured images of the 3-D object from a prescribed set of viewpoints. The approach is based on the shape-from-silhouette (SFS) technique, and the efficacy of the SFS method is tested using a sample data set. The extracted three-dimensional shape is modeled with polygons generated by a new iterative triangulation algorithm, and the polygon model can be exported to commercial software. The proposed system may be used to visualize the 3-D object efficiently, or to quickly generate initial CAD data for reverse engineering purposes, including three dimensional design applications such as 3-D animation and 3-D games.

The fast extraction of the silhouettes of a model is very useful for many applications in computer graphics and animation. In this paper, we present an efficient algorithm to compute a sequence of perspective silhouettes for a polyhedral model from a moving viewpoint. The viewpoint is assumed to move along a trajectory q(t), which is a space curve of a time parameter t. Then, we can compute the time-intervals for each edge of the model to be contained in the silhouette by two major computations: (i) intersecting q(t) with two planes and (ii) a number of dot products. If q(t) is a curve of degree n, then there are at most of n + 1 time-intervals for an edge to be in a silhouette. For each time point $t_i$ we can extract silhouette edges by searching the intervals containing $t_i$ among the computed intervals. For the efficient search, we propose two kinds of data structures for storing the intervals: an interval tree and an array. Our algorithm can be easily extended to compute the parallel silhouettes with minor modifications.

We describe the development of an interactive aerobic training system using vision-based motion capture and multimedia technology. Unlike the traditional one-way aerobic training on TV, the proposed system allows the virtual trainer to observe and interact with the user in real-time. The system is composed of a web camera connected to a PC watching the user moves. First, the animated character on the screen makes a move, and then instructs the user to follow its movement. The system applies a robust statistical background subtraction method to extract a silhouette of the moving user from the captured video. Subsequently, principal body parts of the extracted silhouette are located using model-based approach. The motion of these body parts is then analyzed and compared with the motion of the animated character. The system provides audio feedback to the user according to the result of the motion comparison. All the animation and video processing run in real-time on a PC-based system with consumer-type camera. This proposed system is a good example of applying vision algorithms and multimedia technology for intelligent interactive home entertainment systems.

This research was analyzed regarding comparing features of expressions between clothes in movie, , and cyber clothes that were made by Marvelous Designer2 which is a design CAD. This research was studied to experiment an expressing possibility of clothes simulation software which was developed currently. Therefore, we picked clothes that are good at movement and detail in the movie. The dress theory of the renaissance which is the period background of movie, was considered and studied as pattern, silhouette, material, color, detail and animation. The movie's dresses are made with 3D virtual and compared so 3D virtual clothes's benefits and weaknesses can be analyzed. As a result, we found that 3D virtual dress can show the real movie's feature accordingly with current developed IT standard. This will assist a development in fashion industry and become a new indicator for 3D movie clothing.

Nowadays, many computer games based on NPR(Non-photorealistic Rendering) techniques have been developed due to their distinctive visual properties. However, only limited methods of NPR techniques have been exploited in producing computer games and amongst them cartoon-style rendering techniques especially has had the special interest. In the paper, we suggest an effective rendering method of comic-book style that will be applicable to computer game. In order to do, we first characterize the properties of comic-book from comparing two visuals: celluloid animation and comic-book. We then suggest a real-time rendering method of comic-book style represented by outline sketch, tone, and hatching. We finally examine its effectiveness by observing the game developed using the method.

Among elements of play, there are puppets performances and shadows performance which are replacing actors by puppets and shadows. Puppet performance is characteristic of expressing various movements and symbols at its conveniences by the reduced models of human form with various materials. Shadow performance is realized in various colors that cannot be discovered in other countries by expressing mysterious cubic effect in reflecting the light against various forms. Mansukjung Nolum is a unique shadow performance that has been inherited in Korea. There are found many shadow performances inherited in the northern Europe and South-eastern Asia. Recently the silhouette animation in application of shadow performance is made. In the northern Europe and South-eastern Asia, they performed in white and black color while Mansukjung Nolum is performed in natural colors. Since they adopted the leather materials for making puppets, their opaque feature cannot reflect the colored light. But in Korea we adopted the specially colored semi-transparent Korean paper, which gives the colored shadows to spectators. Mansukjung Nolum consists of three acts for arousing attention of fallen monks destroying the teaching of Buddha. Seosanbakchumji Nolum is a puppet performance inherited in a village in Seosan, Choongnam instead of wandering artists. The story and form of performance in Namsadangpae's puppet play is mostly similar to it, but it is woven by its villages natural environment and specific dialects, reflecting their consciousness in mind. The villagers made the puppets and manipulate them in communicating their wisdom of life between them. Parkchumji Nolum is a kind of integral art combining puppet manipulation, witticism, songs and dances. The hero of Parkchumji discloses the social and structural conflicts of feudalism, in arousing the spectators' rich attention of self-awareness and lessons.

The culture includes every possible objective forms created by humans and their shared aspects of ideas, feelings, and behaviors, beliefs and etc. The dress and its ornaments are part of the culture that expresses the relationships in objective ways and in formless immaterial ways. The school uniform represents significant meanings to the students in their school years, and it is the way of expressing their individuality and full filling their needs for self-presentation. Therefore, understanding and analyzing youth culture means understanding students' school uniform along with fast changing twenty first century civilization. Korea and Japan are very close nations to each other. Both Korean and Japanese girls' school uniform style were adopted western clothing style and went through many changes based on cultural differences between two countries. They are affected by different peculiarities between two nations and youth cultures from different cities. Therefore, this research is on analyzing how different visual values of girl's high school uniforms in Seoul and Tokyo and understanding youth cultures through macro-analysis. The youth cultures in Korea and Japan are mostly similar but there is special development on animation in Japan and possibly can find many styles of girl's high school uniform. Both nations are varying to be opened to sexual culture of adolescents but Japan is more uninhibited than Korea. In Japan, sailor-uniform can be found in fetish way in public culture. On one hand, because of most private girl's high schools in Tokyo takes an entrance examination, top-ranking students are very proud of their school uniforms and even students from other public high schools get private high school uniforms to attend school festival. This analysis showed that private girl's high school uniform in Seoul appealed as slim fitted silhouette which is close to modem woman's suit style while in Tokyo appealed as boxy style matched with short pleated skirt or sailor-uniform style. Comparing that to school uniform photos taken on the street, we can find that alikeness or more extreme styles as examples. These are influenced by different youth cultures in Seoul and Tokyo and cultural differences stands for different aesthetic norm being accepted or rejected.
