This paper presents a visual tracking algorithm for the golf swing motion analysis by using the information of the pixels of video frames and movement of the golf club to solve the problem fixed center point in model based tracking method. The model based tracking method use the polynomial function for trajectory displaying of upswing and downswing. Therefore it is under the hypothesis of the no movement of the center of gravity so this method is not for the amateurs. we proposed method using the information of pixel and movement, we first detected the motion by using the information of pixel in the frames in golf swing motion. Then we extracted the club head and hand by a properties of club shaft that consist of the parallel line and the moved location of club in up-swing and down-swing. In addition, we can extract the center point of user by tracking center point of the line between center of head and both foots. And we made an experiment with data that movement of center point is big. Finally, we can track the real trajectory of club head, hand and center point by using proposed tracking algorithm.

In this study, we sought to find out the effect of different emotional interior images of the community facilities in an apartment complex on a youth brain wave by analyzing an Electroencephalograph (EEG). Based on the frequency of usage, we selected learning facilities, cultural facilities, and sport facilities. For brain stimulation, the visual stimulants with three different emotional words, cheerful, gentle, and elegant, were used based on I.R.I image scale. Overall, total nine different emotional images were used. Based on our findings, we conclude that: first, in order to improve learning concentration of the youth, a learning facility for the youth needs to be designed by skillfully combining the soft and comfortable colors from the gentle image and the murky and dark colors from the elegant image. Second, when designing a cultural facility, it is preferable to consider the elegant image for a calm and comfortable space. Third, a sport facility design needs to preclude dark colors and apply light colors to create a dynamic and lively space. Furthermore, we found out that the youth has established static images of each functionally different facility through their experience and learning. Therefore, it is imperative to plan community facilities in an apartment complex in a way to connect the space function with the emotional characteristics of the youth in order to support and encourage energetic activities and learning of the community youth.

A science museum responds independently based on the exhibits and exhibition environments as the visitors are different in purposes, interests and demands. Therefore a science museum should be designed keeping it in mind that there are various ways for visitors to perceive and use the exhibition spaces and exhibits. The purpose of this study is to compare and analyze the characteristics of sensory receptors for the exhibits in National Museum of Nature and Science's Global Gallery, Tokyo, in terms of information transmission and to identify the nature of exhibit medium that can affect the perception and recognition of the exhibits by visitors. Through these 9 sensory receptors, human recognizes first with visual, auditory and olfactory senses and reacts using vestibular organ, proprioceptor (stretch), tangoreceptor, themoreceptor, taste and olfactory senses. Human uses these information processing to recolonize the external environment. This process is similar to the visitor's information transmission process for the exhibition medium. By dividing the analysis results per exhibition theme and developing the information transmission processing types per sensory receptor, we could understand that the distribution conditions are closely connected with the composition of the exhibition scenario in the exhibtion area. Especially, the understanding of how the information transmission is made through sensory receptors could can be the criteria that determines on the factors that can identify the exhibition purposes of a science museum which are eduction and understanding.

Branding is a process of building the relationship between a brand and consumers. This process can also happen in a space that reflects brand characteristics, and this kind of branding is called space branding. This way can strengthen a brand image by delivering its profound impressions with synesthetic experiential services for consumers. In terms of brand extension, particularly, it is possible by space branding to apply the image and value of the parent brand to spatial design so as to expect the direct effect of experiential brand recognition. As a result of case analysis for space branding - the scope of which was limited to hotels - specific ways of embodying a brand into space were largely classified into three types: the first is the 'embodiment of visual elements' that directly embodies a brand's logos, colors, forms, and textures into space; the second is the 'experience of brand content' that mainly adopts the way of giving impressions with events or customer services, or of inducing direct experiences combined with exhibition function; and the third is the 'symbolic expression of brand characteristics' that indirectly expresses the strong concept or image of a brand - a type in contrast to the first direct type. These ways of space branding change the general abstract feeling of a brand's qualities into specific spatial experiences, thus now settling as one of the ways of marketing that are direct, strongly sustainable, and the most effective.

This study aims to analyze the aesthetic thought and expression tendency appeared in contemporary architecture by looking at today's architectural art based on the concept of the uncanny that Sigmund Freud contended as an aesthetic principle, of the aesthetic concepts tossed around to define the contemporary times in the aesthetics field and discuss the architectural analysis possibility of the concept of the uncanny. The generation structure of the uncanny that generates experiences of fear and surprise is classified into dual structure, trauma, threatening structure, and repetition compulsion. This is the principle that evokes a sense of experiencing subject, incorporates sensibility, and vitalizes internal process. This is also the methodology to organize and structure the concept of the uncanny. When seen from the four factors drawn from the concept of the uncanny and aesthetic expressions, the uncanny expression characteristics of contemporary architecture includes isolation, subversion, trace, absence, oblique line, flotation, concealment, and disturbance. Isolation and subversion refers to producing the space of the pressure of tension and relaxation caused by repression and relief from repression and eliciting the maximum expansion of the sense of space through spatial change. Trace and absence indicates being able to elicit more intense emotions from the experiencing subject by applying the images of alienation and absence in the way to reproduce historical trauma. This happens by implementing the potential value of physical activity. Oblique line and flotation means visual impulse. This happens in the way to visualize uneasy points. This causes uncanny by threatening the survival. Finally, concealment and disturbance refers to creating unpredictable space. The concept of masquerade and maze space composition are applied in the way to activate spatial perception, including space exploration and unintended subject's forced selection. As stated above, the uncanny expression characteristics shown in contemporary architecture can be presented as indicators that are available to analyze the undecided and diversified contemporary architecture aesthetically. In this respect, this study has great significance.

T-DMB (Terrestrial-DMB) service is now available in the metropolitan area, but due to the bandwidth limitation, it is allowed to provide up to CIF resolution. As users' requests for high-quality mobile multimedia services are rapidly increasing and additional bandwidth can be provided by adopting the hierarchical modulation transmission technology, the research on the Advanced Terrestrial-DMB(AT-DMB) service using the SVC(Scalable Video Coding) scheme is being actively studied. In this paper, through computer simulations, first, while keeping the current T-DMB service unchanged, the visual qualities of AT-DMB services are investigated by varying the additional bandwidth. Then, by considering the cases that the overall bandwidth can be allowed to dynamically allocate to the T-DMB/AT-DMB video services, the performance characteristics between two layers are compared over the different kinds of video sequences.

We heat treated pure sapphire samples at $1800^{\circ}C{\sim}100$ hours in BeO-${Al_2}{O_3}$ powder by varying BeO contents of $5{\sim}50\;wt%$ in order to quantify the BeO diffusion enhancement for corundum gem stones. We investigated the heat treated samples with visual evaluation, color coordination analysis, and surface roughness measurement. We confirmed that $Be^{2+}$ ions did not lead to orange color but to dark gray. The lightness in CIE Lab index decreased while surface roughness increased rapidly as BeO contents increased. We propose that BeO yellow color enhancement may be feasible only for $Fe^{3+}$ rich blue sapphires and sub-5% BeO content be appropriate to shorten post re- cutting process.

People health improvement is becoming new subject through the combining with the oriental medicine diagnosis theory and IT technology. To do this, firstly, it needs sicked data that supply the visualization, objectification and quantification method. Especially, if an ocular inspection can be more objective and visual expression in oriental medicine, it seems to offer the biggest opportunity in diagnosis field. In this study, I propose a diagnosis to check the symptoms of heart diagnosis. Our research aim is on the visualization of diagnosis using image processing system which it can be actual analysis about the symptom of heart. To catch up this study, through the color support assistance by face image processing, I devide the face area and analyze the face form and also extract face characteristic point in heart disease diagnosis using oriental medicine based on an ocular inspection method. I would like to prove the usefulness of the method that proposed by an experiment.

In this work, a new rate control algorithm for transmission of H.264/AVC video bit stream through CBR(constant bit rate) channel is proposed. The proposed algorithm predicts target bit rate and MAD(mean of absolute difference) for current frame considering image complexity variance between neighboring backward and current images. In details, respective linear regression analysis for MAD and encoded bit rate against image complexity variance produce correlation parameters. Additionally, it uses frame skip technique to maintain bit stream within a manageable range and protect buffer from overflow or underflow. Implementation and experimental results show that the proposed algorithm can provide accurate bit allocation, and can effectively visual degradation after scene changes. Also our proposed algorithm encodes the video sequences with less frame skipping compared to the existing rate control for H.264/AVC.
