This article analyzes the background representation of 3D animation and look at what its proper background expression. With the development of computer graphics technology, the background of the 3D animations can be expressed as The actual background. In contrast, "The Smurfs" which was released recently was created to take the actual background. However, 3D animation with real background is not appropriate in terms of creative expression space in the main role of the animation. In this Study, we analyze the character and background of the animation made in 3D graphics. Based on this, we propose a correct representation of 3D animation background.

The infringement of the copyright is a problem by the distribution of digital contents copied illegally. The digital watermark is expected as a thing preventing unjust copying by burying information in digital data such as image, animation, the sound, TV, radio and movies. [1] [2]But a noise is included in a digital watermark reproduction image. So there is the case that the certification of the reproduction image has difficulty with. If a computer cannot recognize the information reproduced from digital watermarking, the information does not have a meaning. This paper aimed at improvement of the proof of a digital-watermarking reproduction image. And it is verified whether the difference of the form of a character affects the degree of correlation.

In recently, annealing process of cold rolled sheet tend to change to continuous annealing process for improving qualify, saving yield. In the meantime as demand for various kind and small lot of products has been increasing, batch annealing has been appreciated for its small restriction for the operation. So, we tested on the effect for a hydrogen contents of atmospheric gas at annealing furnace. As a result of several investigation. We confirmed for the following characteristics ; improved productivity, uniform heating, improved surface quality, saving energy. Therefore, the use of hydrogen instead of nitrogen as the protective gas, combined with high convection in batch annealing furnaces, has shown that considerable increases in furnace output and material quality are attainable. Owing to the low density, high diffusion and reducing character of hydrogen, a better transfer resulting in uniform material temperatures and improved coil surfaces can be achieved.

Optical Character Recognition (OCR) that has been a main research topic of computer vision and artificial intelligence now extend its applications to detection of text area from video or image contents taken by camera devices and retrieval of text information from the area. This paper aims to implement a binarization algorithm that removes user intervention and provides robust performance to outdoor lights by using TopHat algorithm and channel transformation technique. In this study, we particularly concentrate on text information of outdoor signboards and validate our proposed technique using those data.

Along with the advance of digital technology, various methods are adopted for capturing the 3D animating data. Especially, in 3D animation production market, the motion capture system is widely used to make films, games, and animation contents. The technique quickly tracks the movements of the actor and translate the data to use as animating character's motion. Thus the animation characters are able to mimic the natural motion and gesture, even face expression. However, the conventional motion capture system needs tricky conditions, such as space, light, number of camera etc. Furthermore the data acquired from the motion capture system is frequently corrupted by noise, drift and surrounding environment. In this paper, we introduce the post production techniques to stabilizing the jitters of motion capture data from the low cost handy system based on Kinect.

As a series of the studies of EPDM-Polymer blends, the experiments are concentracted to the investigation of the physical properties of the EPDM-NBR blends. The results are shown as follows; 1. As EPDM addition ratio is increased, the physical properties such as resistance to ozone and aging have also improved, on the other hand, elongation and abrasion resistance decreased. 2. Tear strength is less influenced by blending and character after aging exhibited the same result. 3. Tensile strength decreased with increase in EPDM contents, especially the ratio of EPDM/NBR are 50/50 and 75/25.

In this paper, we present a method for reconstructing a surface mesh animation sequence from point cloud animation data. We mainly focus on the articulated body of a subject - the motion of which can be roughly described by its internal skeletal structure. The point cloud data is assumed to be captured independently without any inter-frame correspondence information. Using a template model that resembles the given subject, our basic idea for reconstructing the mesh animation is to deform the template model to fit to the point cloud (on a frame-by-frame basis) while maintaining inter-frame coherence. We first estimate the skeletal motion from the point cloud data. After applying the skeletal motion to the template surface, we refine it to fit to the point cloud data. We demonstrate the viability of the method by applying it to reconstruct a fast dancing motion.

The fishermen around fishing villages have organized the Eo Chon Gae, a co-operative organization based on the Fisheries Co-operative Law. The Eo chon Gae plays a vital role in the fishing village community, and the common economic, administrative and social profits are expected by members. The members of the Eo Chon Gae must work together in a common coastal fishing ground, this fishing ground is jointly owned by the community, and the members have to conduct the Eo chon Gae jointly for their common profit. This system, as mentioned above, is called the Eo Chon Gae, which is generally called a fishing village community, or a fishing administrative community. The purpose of these theses is to consider what kind of character and principles the Eo Chon Gae has. The contents of these theses are divided into six parts: 1. The various concepts of the fishing administrative community 2. The progress of the Eo Chon Gae. 3. The organization of the Eo chon Gae. 4. The purpose of the Eo chon Gae. 5. The work of the Eo Chon Gae. 6. Types of the Eo Chon Gae.

Purpose: The purpose of this research was to explore the cyber world immersion experience of adolescents. Method: Multiple strategies for data collecting were used: an in depth face-to-face interview; analysis of adolescent' writings; and analysis of examples of phenomenon in the realistic world. The sample group consisted of 10 adolescents. Results: Although the experience was different for all adolescent interviewed, the essential themes of experience emerged: "fill up", "homoeologous feeling", "the older generation has a conflicting negative opinion", "change in social character", "become habitually skeptic", "have bad health", "mean of superiority and getting everything solved", "ease of access", "monetary benefit", "addiction to the computer", "forget real life solved stress", "do harm to society", "take comfort", or "new job". Conclusion: Accordingly this paper suggests that contact with various software is necessary in adolescents, and good quality contents function to prepare and activate adolescents to apply the internet for good use.
