Recent development in virtual and augmented reality increases the demand for content in many different fields. One of the fast ways to create content for VR is 3D modeling of real objects. In this paper we propose a system to reconstruct three-dimensional models of real objects from the set of two-dimensional images under the assumption that the subject does not has distinct features. We explicitly consider an object that is made of one or more surfaces and radiant constant energy isotropically. We design a low cost portable multi camera rig system that is capable of capturing images simultaneously from all cameras. In order to evaluate the performance of the proposed system, comparison is made between 3D model and a CAD model. A simple algorithm is also proposed to acquire original texture or color of the subject. Using best pattern found after the experiments, 3D model of the Pyeongchang Olympic Mascot "Soohorang" is created to use as VR content.

In this paper, we propose a new approach to learning a discriminative model for figure/ground segmentation by incorporating the bag-of-features and conditional random field (CRF) techniques. We advocate the use of image patches instead of superpixels as the basic processing unit. The latter has a homogeneous appearance and adheres to object boundaries, while an image patch often contains more discriminative information (e.g., local image structure) to distinguish its categories. We use pixel-level sparse coding to represent an image patch. With the proposed feature representation, the unary classifier achieves a considerable binary segmentation performance. Further, we integrate unary and pairwise potentials into the CRF model to refine the segmentation results. The pairwise potentials include color and texture potentials with neighborhood interactions, and an edge potential. High segmentation accuracy is demonstrated on three benchmark datasets: the Weizmann horse dataset, the VOC2006 cow dataset, and the MSRC multiclass dataset. Extensive experiments show that the proposed approach performs favorably against the state-of-the-art approaches.

Suhainmyuldo(수하인물도) is a kind of picture which express a person under the tree and is known to be transmitted from the Middle Asia. The origin of this kind of expression is assumed to be from Iykshini(=Iygsha), the fairy of tree, in India of from the 'Tree of Life' in W. Asia, and they had in fluenced on the craft art design of Chinese art. However, Chinese art had already developed the motif of this kind in its unique way. For example, Jookrimchilhundo(죽림칠현도: seven wise men in bamboo forest), during Six Dynasty. The tree of life(arbor vitae, lignum viate), the origin of the Painting of figure under a tree(수하인물도), was spreaded in several regions around the center of Mesopotamia early, and them transmitted to Sasan dynasty of Persia, even to Islam, Byzantine, Romanesque, ancient East Asia. The mural painting found in the 4th Tongu Ogoe tomb, which was created after the 5th Tongu Ogoe tomb, used Obangsaek more than the 5th tomb painting did. (The term Obansaek refers to the five Korean traditional colors consisted of yellow, blue, white, red and black) The mural painting on the 4th Ogoe tomb employed distinct technique to depict an object in a certain color by painting the surroundings with different primary colors, making the painting look more exotic and mysterious.

The purpose of this study was to analyze the formative beauty of metro sexual expressed on the 21C men's fashion. in 21C, metro sexual is being accepted as an object to lead the world consumption culture, and it is said to be most appropriate to the definition as a model that can determine the most modern men. Moreover, with well being life style, it shows characteristic that expresses chic sense through fashion. The results of the study were as below. 1. In recent men's wear, sensory feminine that looks young and trendy is being presented through clothes, rather than the image of men who are strong. Therefore, by wearing splendid flower print, bold color and gorgeous accessories, men send off their attractions. 2. The recent body king syndrome gave new aesthetic value on men's body. Therefore, men's body is becoming cultural icon of metro sexual as another face that shows social status and cultural taste. 3. The men's image of metro sexual that is felt from softer skin and hair than women, and well-built body is appealing more through body conscious look. Here, men's body silhouette is being sublimated aesthetically through design with various materials such as see-through and leather etc., and this is body conscious image that can be seen only in metro sexual. Like this, metro sexual fashion sense was expressed by feminine softness sometimes, and beautiful body silhouette sometimes by expressing one's sexiness enough, being away' from conceptual masculine. Therefore, the appearance of metro sexual can be understood that men's body exposure is becoming a social virtue that expresses beauty.

This research is to aim at presenting arrangement of colors, visual and symbolic through combined coupling ofI-Ging and Sackdong. This combined couplings is attempted to be approached by the following 4 conceptual steps :ⅰ) Is it appropriate to even try to coupleI-Ging with Sackdong\ulcorner ⅱ) Is the basic structure of Kwai an object of stripe colorizing\ulcorner ⅲ) What are the fundamental colors for this purpose\ulcorner ⅳ)combined of Kwai and the fundamental colors. Theoretical background for this study is as follows.ⅰ) Color accord and arrangements of existing Sackdong. ⅱ) An attempt to coupleI-Ging with Sackdong The purpose of this research is to expand concrete concept of Sackdong, which is to be utilized not only in costume design, but in the whole realm of design, by presenting feasible application of stripe coloredI-Ging. The summary of conclusion of this research is as follows. A. Is this aforementioned attempt academic\ulcorner B. Standardization of stripe-coloring is essential. Furthurmore we can conclued that the under-standing ofI-Ging and its basic philosophical background and the fundamental mechanism of colors in traditional costumes is necessary condition for standardization of Kwai. Along this path, however, conditions to be satisfied and priorities to be given depend upon the decision of an individual or a group. In my view, sripe-colorizing of 64 Kwais ofI-Ging followed by intuitive matching of colors with the in-terpretation of Kwais seems to be the most appropriate solution.

The purpose of this study was to supply the opportunity of being used as a material which can predict future fashion. This study had been divided the symbolic meaning into three parts. The first part was the symbolic expressions in the materials of modern fashion, and the second part was symbolic meaning which was expressed in the accessories, and the last part was the symbolic meaning which was expressed in the physical ornament. The results could be summarized as follows. First, among the forms of heraldry were expressed in modern Fashion, were such as animals like a lion and eagle, which evoked the powerful and lively mood. A vegetable heraldry was expressed on a pattern of textile fabric to pursue the beauty of dress, represented female and classical beauty. A inanimate object heraldry was included all natural material that didn't have all lives the world, represented the mystery and intensity of nature as using the design that sets off the idea through color and figure. Second, in the case of being the forms of heraldry used as a mark or logo in modern fashion, it was visualized the fashion of traditional sense, marine look and military look. This mark or logo had important characteristics of symbolic in that the product had a special meaning and function by trade mark. Third, tattos were used to heighten the people's union in the various subordinate cultures. By ornamenting their bodies, they expressed their special identity and consciousness. Tattos represented a unique menas, which effected a mood of fashion.

This study examines black images as 'the other' in history and aims to analyze images of black female fashion models which have been changed in modern society, particularly in $21^{st}$ century post-modern world. Black images, established historically as illustrated on the paintings in $19^{th}$ century, were disseminated in $20^{th}$ century throughout the world especially by way of TV and movies as several typical images such as 'Coon' the clown as the object of entertainment, 'Buck' wild and resistant black rascal, and 'Mammy' obedient and fat black woman servant. The result of image analysis of black female fashion models, can be summarized as following five images. The first is the image of 'powerful'. Black female models frequently represent healthy image which reflects black people's excellence in sports and also the traditional Image of black skin color as strength. The second is the image of 'sexy'. They are adored as having perfect ideal body shape. They show off their sex appeal with their body. The third image is 'multicultural'. Black models represent cultures besides the western. The fourth is the image of 'fantastic'. In contrast to the real, resonable things, black female models represent wild, fancy, ghost things. The fifth is the image of 'racial discrimination' By arranging them in contrast to whites, a metaphoric image of racial discrimination can be displayed. The result shows that tome of racial images still remain on the other way.

Lane detection is a widely researched topic. Although simple road detection is easily achieved by previous methods, lane detection becomes very difficult in several complex cases involving noisy edges. To address this, we use a Convolution neural network (CNN) for image enhancement. CNN is a deep learning method that has been very successfully applied in object detection and recognition. In this paper, we introduce a robust lane detection method based on a CNN combined with random sample consensus (RANSAC) algorithm. Initially, we calculate edges in an image using a hat shaped kernel, then we detect lanes using the CNN combined with the RANSAC. In the training process of the CNN, input data consists of edge images and target data is images that have real white color lanes on an otherwise black background. The CNN structure consists of 8 layers with 3 convolutional layers, 2 subsampling layers and multi-layer perceptron (MLP) of 3 fully-connected layers. Convolutional and subsampling layers are hierarchically arranged to form a deep structure. Our proposed lane detection algorithm successfully eliminates noise lines and was found to perform better than other formal line detection algorithms such as RANSAC
