The rosette-scan seeker, mounted on the infrared guided missile, is a device that tracks the target It can acquire the 2D image of the target by scanning a space about target in rosette pattern with a single detector Since the detected image is changed according to the position of the object in the field of view and the number of the object is not fixed, the unsupervised methods are employed in clustering it The conventional ISODATA method clusters the objects by using the distance between the seed points and pixels So, the clustering result varies in accordance with the shape of the object or the values of the merging and splitting parameters In this paper, we propose an Array Linkage Clustering Algorithm (ALCA) as a new clustering algorithm improving the conventional method The ALCA has no need for the initial seed points and the merging and splitting parameters since it clusters the object using the connectivity of the array number of the memory stored the pixel Therefore, the ALCA can cluster the object regardless of its shape With the clustering results using the conventional method and the proposed one, we confirm that our method is better than the conventional one in terms of the clustering performance We simulate the rosette scanning infrared seeker (RSIS) using the proposed ALCA as an infrared counter countermeasure The simulation results show that the RSIS using our method is better than the conventional one in terms of the tracking performance.

The existent UCC sites display only finalized contents by publisher. It dose not provide any platform for resources of UCC that public users could reorganize. This paper has developed a platform to be able to produce reusable content using the scenes of the contents and produced a 3D animation with multiple story. It is necessary for user to search the provided contents for easy reorganization of the contents. The scene is classified by the description and information of the scene for handy search. It is obscure for a movie clip to be represent with only one word. Therefore, the proposed platform provides the search technique with a overlapping choice for the specific categories that include most of elements for the scene. Then the user can choose a specific range of the selected movie clip, make a new story with reorganizing the order, and put a caption or BGM on the movie clip. The complete movie clip has the search preferences as a category, new clips, and top favorites. With the Multi-Story line concept, we made a 3D animation about episodes of thermal dolls in the Doll World. This attempt will come to the new marketing way for a field of the visual media like as Music Video, Drama, Feature Film, Commercial Film.

In this paper, we present a practical method for generating facial animation by using an optical motion capture system. In our setup, we assumed a situation of capturing the body motion and the facial expression simultaneously, which degrades the quality of the captured marker data. To overcome this problem, we provide an integrated framework based on the local coordinate system of each marker for labeling the marker data, hole-filling and removing noises. We justify the method by applying it to generate a short animated film.

Most films have not made by original storytelling. They get their storylines and themes from diverse sources such as novels, comics, performing arts, and previous film products. Comics have become a primary source for film production since 1960s in such nations as Japan and USA. In the contemporary period, this becomes a more visible trend in many countries including Korea, China, and France. Unlike novel, comics combine words with images. Since a comic strip isa graphic medium in which visible images are created in order to express a sequential narrative, it seems more relevant when films adapt original comics in order to recreate new products. The progress of 3D graphics technology enables film creators to realize imagined images in screen, most of which were once imagined only in comics. Keeping an eye on the strength of comics, this study tries to tries to investigate the relationship between a comic strip and its adaptation to film. It will firstly discuss the cases of comics in Korea, which are adapted to film in Korea. And this study will discuss "Le Grand Chef"as a case study in order to investigate what is the difference between original comics and film adaptation.

In the future there would be many kinds of digital images for many industrial markets. 3D stereoscopic images for variable fields; medical operation, film and animation, broadcasting, internet, game, or design for art and architecture. And many people to work about computer programming, and digital image making will concern about it more and more. However, these kinds works and studies are focused on the professional technical fields like 3D display or computer programming technology so far. To revitalize the market of a variable stereoscopic contents, there should build up the foundation for easy processing of the making stereoscopic images. This paper is based on stereoscopic making skills for anaglyph system. An anaglyph system has an old history about making stereoscopic images, and very simple method to produce the stereoscopic images. Particularly this study is focused on color compositing technique, and camera positioning on the compositing system. It will help optimization of the environments to create 3D motion graphic and animation contents.

This article intends to draw the Road map of Korean International Animation Festival through the research of background and its identity of 4 International Animation Film Festivals Such as Annecy, Zagreb, Ottawa and Hiroshima. I was given opportunity to visit Annecy since 2009, it brought me to the real attraction of animation for watching of pleasure and passion of the people those who love animations. For the combining more advanced system and structure for Animation Festival in Korea, I had to do research all the information from the documents from the Annecy Collections. though I have not get the chance to go others except Annecy, However, I could get their background and history whenever I met the other Festival Committee Members. These Festivals showed us successful Road Map for the Animation Festivals in Korea as a role model. For the getting advanced system of Animation Festivals in Korea. It requires the animation theater for animation, effort for the Audiences's Convenience and international network composition system. However, the last task of us is to make people to entertain and enjoy the animation Films, its world of attraction.

Digital cinema based on digital master distribution increases with stereoscopic film as the center. DCI specification V1.0 announced at 2004, it considerates stereoscopic film screening. And now, the Society of Motion Picture and Television Engineers is establishing a task force to define the standards of a stereoscopic contents viewed in the home. Today, most Hollywood commercial stereoscopic film features animation using computer graphic. However, considering film making characteristic, stereoscopic digital cinema is required shooting in real world and editing, screening. This paper presents possibility of stereoscopic examination at NLE in the stereoscopic workflow. And we will propose new stereoscopic digital cinema workflow to apply the stereoscopic examination. Based on experimental results, the 3D ready television using 120Hz has some obstacles for contents editing, but most domestic stereoscopic monitor using circular polarization is possible for successful editing.

In the modeling processes of 3D computer animation, methods to build optimal work conditions to realize real forms for more efficient works have been advanced. Digital sculpting software, published in 1999, ZBrush has been positioned as an essential factor in character model work requiring of realistic descriptions through different manufacturing methods from previous modeling work processes and easy shape realization. Their functional areas are expanding. So, in this production case paper, as a method to product more optimized animation character models, the efficiency of production method linking digital sculpting software (Z-Brush) and animation production software (Maya) was deliberated and its consequences and implications are suggested. To this end, first the technical features of polygon modeling and Retopology were reviewed. Second, based on it, the efficiency of animation character modeling work processes through step linking ZBrush and Maya suggested in this paper was analyzed. Third, based on the features drawn before, in order to prove the hypothesis on modeling optimization method suggested in this paper, the production process of character Dumvee from a short animation film, 'Cula & Mina' was analyzed as an example. Through this study, it was found that technical approach easiness and high level of completion could be realized through two software linked work processes. This study is considered to be a reference for optimizing production process of related industries or modeling-related classes by deliberating different modeling process linked systems.

From game consoles to TV and Hollywood films, 3D rendering technology is involved in various fields. Up until the late 90s, the computer image rendering method was rasterization that mainly used Phong Shading, and up until recently it was the go-to method for movies and film animation. In the 21st century, the quality provided by Ray Tracing and the development of Global Illumination was much more realistic and thus became popularized. However, despite its growing use in architectural rendering to the markets, Global Illumination in film animation and movies was limited due to its long render time. So, in this thesis, if one were to take the concept from each rendering method and consider it from a mathematical perspective, one could adapt the Ambient Occlusion's equation to the illumination loop equation used in rasterization. This algorithm modification has the capability to reflect the lighting of a diverse array of colors, like in Global Illumination, with a fast render time, as in rasterization, and the example RenderMan Shader is based upon this new algorithm. In conclusion, with Global Illumination's naturalistic lighting and rasterization's rendering speed, the combination of the best points of each is a new method with a short rendering time while producing good quality. I hope animations and films can benefit from this algorithm by the reduction of budget with an overall better quality output in VFX production.
