  • This paper presents a novel approach to control the augmented reality (AR) objects robustly in a marker-less AR system by fingertip tracking and hand pattern recognition. It is known that one of the promising ways to develop a marker-less AR system is using human's body such as hand or face for replacing traditional fiducial markers. This paper introduces a real-time method to manipulate the overlaid virtual objects dynamically in a marker-less AR system using both hands with a single camera. The left bare hand is considered as a virtual marker in the marker-less AR system and the right hand is used as a hand mouse. To build the marker-less system, we utilize a skin-color model for hand shape detection and curvature-based fingertip detection from an input video image. Using the detected fingertips the camera pose are estimated to overlay virtual objects on the hand coordinate system. In order to manipulate the virtual objects rendered on the marker-less AR system dynamically, a vision-based hand control interface, which exploits the fingertip tracking for the movement of the objects and pattern matching for the hand command initiation, is developed. From the experiments, we can prove that the proposed and developed system can control the objects dynamically in a convenient fashion.

  • 영상에서 사람의 머리위치를 찾는 문제에 있어서 어깨선 정보를 이용하는 것은 아주 유용하다. 영상에서 머리 외곽선과 어깨선의 형태는 일정한 변형을 유지하면서 같이 움직이므로 이를 ASM(Active Shape Model) 기법을 사용해서 통계적으로 모델링 할 수 있다. 그러나 ASM 모델은 국부적인 에지나 그래디언트에 의존하므로 배경 에지나 클러터 성분에 민감하다. 한편 AAM(Active Appearance Model) 모델은 텍스쳐 등을 이용하지만, 사람의 피부색, 머리색깔, 옷 색깔 등의 차이로 인해서 통계적인 학습방법을 쓰기가 어렵고, 전체 비디오에서 외모(Appearance)가 시간적으로 변한다. 따라서, 본 논문에서는 외모(Apperance) 모델을 변화에 따라 바꾸는 대신, 영상의 각 화소를 머리, 어깨, 배경으로 구분하는 분별적 외모 모델(discriminative appearance)를 사용한다. 실험을 통해서 제안된 방법이 기존의 기법에 비해서 포즈변화와 가려짐, 조명의 변화 등에 강인함을 보여준다. 또한 제안된 기법은 실시간으로 작동하는 장점 또한 가진다.

  • This study investigated the ideal female beauty in advertisement images through the iconological comprehension of Renaissance portraits and explored the longitudinal change of the ideal female beauty in modern Korean society. A total of 146 cover images on Hyang-Jang magazine, which is the company magazine of AMORE PACIFIC Group, from 1972 to 2012 were selected as the data. These images were divided into 10-year units for analysis using iconological criteria, which were pose, shape of eyes and lip, and hairstyle. The way presenting the cover images on Hyang-Jang magazine had changed in order to emphasize female body, self-satisfaction and independence of female, and sexual attractiveness of female. The results of this study implied that the change of ideal female beauty had been affected by socio-cultural contexts of modern Korean society that has industrialized and democratized in a short period of time.

  • Garment manufacture represents the final stage of processing a finished fabric. The main task of the garment manufacturer is to produce shell structures out of flat fabrics to match the shape of the human body, and the most acceptable means of joining textile materials for apparel use is by sewing. On the sewing process, the bottom layer is pushed forward by the feed-dog, but the presser foot tends to retard the passage of the top layer. Since the friction between the layers is low, is possible that the components will move out of phase and pucker. (omitted)

  • In this paper, we propose a new gel-type biomimetic variable-focus lens system. The miniaturization of conventional lens system is limited due to the use of a set of glass lenses for adjusting the focal length. Biologically inspired by the focus adjustment mechanism of the human eye, a gel-type single lens system with variable-focus is presented. The proposed system consists of a gel-type lens, mechanical parts such as body, rotation ring, and winding-type SMA actuator. In addition, the proposed system is designed to operate with a simple and miniaturized mechanical structure using a new attachment and driving mechanism. The focusing performance of the proposed system is verified through a series of experiments and measurements of the shape of the lens using tomography.

  • Clothing must have the individual beauty and the function that one can do one's body movement freely. therefore, from the human engineering view point, the exact measurement of the human body and the analysis of it's results must be applied to clothing because the arm works most. In this study, the skin surface of arm was investigated by shell made of Alginate of each movement. And by sometic method the rate of expansion and contraction of each section, inter-relation among the bust girth, axillary arm girth and scye girth and between the shoulder length right and the under axilla waist length were calculate4d. With these results, cap height, breadth of a sleeve and arm hole girth of existing sleeve pattern have been compared and analysed. The results are as follows; 1) According to the developmental figures of shell, the whole area change was small but that of shape was remarkable in M 4, 9, 13. The change of the Block 1 was particular. 2) Over arm length was contracted in all movements except M6 and under arm length expanded. The changes of sections a, b, c are large, while those of sections d, e are small. 3) In terms of latitudes, change of fore-arm region was small. The rate of scye girth varied from 14.3% of M13 to-5.6% of M2. The breadth of a sleeve expanded in all movements, and especially the front region expanded more than the back. 4) The relation between the shoulder length right and under axilla waist length, in all occasions, was contracted mutually, and one contracted, the other expanded. Therefore, in clothing construction when we consider the function of the arm it is better to widen the arm hole and the breadth of a sleeve at the same time than no widen the shoulder length by lowering the upper part of the upper side seam line.

  • Chang San-roe re-explained the contents from the 30th question to the 47th question of "Nan Jing" which refered to the Chang-Pu and physiological theories as follows through the western theory which wss different from the tranditioonal chinese theory 1. "Nan Jing" refered to the circulation and the coming into being of Yeong-Wi. He denied that it was classified Yeong from Wi or Eum from Yang. 2. He denied that Sam-Cho was separated to three parts and the theory of "Sam-Cho is name only, not shape", using western medical theory. 3. He denied the view about "Left side is kidney, right side is Myung-Mun" because it was incorrect that kidney was separated to two parts which were Su and Hwa or Eum and Yang 4. Re-explaining the contents of "Nan Jing"- the portions of heart and lungs, the rising and falling of liver and lungs, the relationships of five viscera and sound color smell taste fluid, the relationships of five viscera and nine hole, the relationships of five viscera and O-Chu, the physiological difference of the old and the young owing to the deflection of Yeong-Wi Chi-Heol- he thought that viewing the human body using theory of Eum and Yang, Five elements(五行) was a far-fetched interpretation, so he denied the tranditional chinese theory which understood human body's organs, physiology, pathology. 5. He explained the contents of "Nan Jing"- the portions of the colon and the small intestines, the funtion of the six bowls, the corespondence of Chang-Pu, physical peculiarity of liver, the anatomical aspects which were the sizes, weights, volumes and shapes of the Chang-Pu and the alimentary canal, Chil-Chung-Mun, Pal-Hoe-Hyeolthrough western anatomy and physiology in detail.

  • Considerable number of women are enjoying swimming, however, the chest-region of swimsuits including cup inserts are not stable during swimming. The purpose of this study was to explore alternate designs and methods of stabilizing the breast cup to the swimmer's body by using 3D technology to design and position the pad and cup pattern of the swimming suit. To position the pad optimally, a 3D pattern of a nude woman was divided into blocks and different reduction rates were applied to blocks around the outlines of the breast. Two types of 3D patterns were developed. The first, referred to as the 'basic 3D pattern' provided for the curved surface of the breast point to be maintained with the remaining slack distributed evenly along the neckline, armhole and side seam. The second, referred to as the '1/3 shoulder moved 3D pattern' ignored the curved nature of the breast point by overlapping, with the resulting position of the shoulder strip moved toward the center. Three women of corresponding size and body shape evaluated the two 3D pattern designs as well as the conventional 2D pattern style of swimsuit. Respondents rated the'the basic 3D pattern' design highest in terms of stability and easy of movement in the chest region.

  • A simulation system for versatile garment drape has been developed. Using this system, the shape of a garment can be simulated in consideration of fabric physical properties as well as the interaction between fabrics and other objects. Each fabric piece in a garment is modeled using a geometrically constrained particle system and its behavior is calculated from an implicit numerical integration algorithm in a relatively short time. The system consists of three modules including a preprocessor for the preparation of fabric patterns and external objects, a postprocessor for the results of three-dimensional visualization, and a drape simulation engine. It can be used for the design process of textile goods, garments, furniture, or upholsteries.
