The concept of the modern consumption is not limited to the value of use by mere purchasing and using of the products. The consumers in modern capitalistic society, consumes the semiotic value whose meaning is socially granted, as well as the value for using. Therefore, that tendency that the symbolic sign of the products is consumed to differentiate oneself from the others and express oneself appears. The designed hotel that reflects the features of sign consumption in the modern society and where the discriminate experience can be enjoyed through the unique and diversified design expression is drawing our attention. Therefore, in this paper, based on the theoretical consideration of semiotics, the tendency of sign consumption and its feature appearing in the modem society has been studied. And through the case studies of the hotels which have been built since the 2000s, how such features can be expressed in the space has been studied. As a result of the study, as for the features of expression of modern semiotic consumption society shown in the design hotels, the diversity breaking from the uniformity by the diversified thinking, the hybrid attribute, and the attribute of the differentiated entertaining images, based on hedonism, the inherent symbols and narrative attribute, and the flexible interactions through the experience of emotional consumption, are appearing.

Since hand gesture recognition was realized thanks to improved image processing algorithms, sign language translation has been a critical issue for the hearing-impaired. In this paper, we extract human hand figures from a real time image stream and detect gestures in order to figure out which kind of hand language it means. We used depth-color calibrated image from the Kinect to extract human hands and made a decision tree in order to recognize the hand gesture. The decision tree contains information such as number of fingers, contours, and the hand's position inside a uniform sized image. We succeeded in recognizing 'Hangul', the Korean alphabet, with a recognizing rate of 98.16%. The average execution time per letter of the system was about 76.5msec, a reasonable speed considering hand language translation is based on almost still images. We expect that this research will help communication between the hearing-impaired and other people who don't know hand language.

The purpose of this study was to analyze and theorize the characteristics of femme fatale in fashion illustration since 1980. The method of this study was to analyze the documentaries for theoretical studies about femme fatale and the visual characteristics in fashion illustration works since 1980. The results of this study were as follows: Femme fatale expressed in the general realm of art was icon of fatal and seductive eroticism in late 19th century. She is composed of diverse images like mythology, exoticism, fear and sensuality. The characteristics of her image in fashion illustration were expressed into de-body image by union of animal and female body, or machine and female body, duplicity of death and sexuality, sexual decadence or abnormality and powerful masculine taste. First, de-body image by union of animal and female body, or machine and female body was expressed in transformed mythical image or bizarre and demonic image, grotesque image linked by picture of female body and painting of animal image, and cyborg image linked by machine and realistic female body by digital media. Second, duplicity of death and sexuality was expressed in juxtaposition by sexual pose, body and something metaphorical and symbolic depiction and de-constructive depiction of death. Third, sexual decadence or abnormality was expressed in fetishistic style, obscene depiction of cheap and hedonistic sexuality, masochistic depiction like antisocial and diseased sex appeal. Forth, powerful masculine taste was expressed in man's face, body, pose, masculine fashion, man's role related to crime and threatening weapon, etc. As mentioned above, femme fatale in fashion illustration was expressed in diverse images by fashion illustrator's point of view. Although she was originated by men's fantastic vision, she brings a catharsis to human being. And she is also recognized as new paradigm and positive cultural sign in our times.

Hand gesture recognition based on vision is a challenging task in human-robot interaction. The sign language of finger spelling alphabets has been tested as a kind of hand gesture. In this paper, we test hand gesture recognition by detecting the contour shape and orientation of hand with visual image. The method has three stages, the first stage of finding hand component separated from the background image, the second stage of extracting the contour feature over the hand component and the last stage of comparing the feature with the reference features in the database. Here, finger spelling alphabets are used to verify the performance of our system and our method shows good performance to discriminate finger alphabets.

사인은 도시와 국가 이미지 형성의 중요한 요소로서 높은 질적 수준이 요구된다. 그러나 국내 사인은 유목성만을 중시하여 눈에 잘 뜨이는 사인을 위주로 제작되는 경향이 있어, 시공될 공간과 조화를 이루지 못하여 시각적 공해의 주요인이 되고 있으며, 사인업에 종사하는 종사자들이 디자인과 관련된 전문적인 지식에 대한 재공급을 매우 필요하게 느끼고 있는 것으로 나타났다. 이러한 현실 속에서 단기적으로 사인 디자인의 질적 수준을 향상시키기 위한 방법으로서 사인 디자인 작업을 주로 하는 사인업계 종사자들에게 사인을 기능적 측면 뿐 아니라 디자인 조형미를 갖춘 양질의 사인을 제작하는데 도움을 줄 수 있는 보조도구로서의 사인 디자인 소프트웨어를 제공할 필요성이 있다. 이에 본 연구에서는 사인을 디자인하고 제작된 사인을 시공 위치에 부착해보기까지 사인 디자인제작 과정을 경험해보고, 사인의 문자정보를 중심으로 관련된 디자인 요소들의 시각적 효과를 알기 쉽게 제공해주는 체험시뮬레이션 소프트웨어 구현 사례를 소개하고자 한다. 소프트웨어 개발을 위해 먼저 문헌 및 선행연구를 통해 사인 제작과정 및 환경을 분석하고, 사인 디자인 요소와 프로그램 구성요소, 사용자 인터페이스 등을 설계하였으며, 객체지향 프로그래밍 언어인 lava를 사용하여 소프트웨어를 구현하였다. 본 연구에서 개발한 소프트웨어는 사인 디자인 관련 학과의 교육교재로서 활용가능하며, 사인의 질적 수준 향상을 도모함으로써 사인에 대한 사회적 인식제고와 학문적 관심을 유도할 수 있을 것으로 기대된다.

본 연구에서는 1/1,000 수치지형도 및 정밀도로지도 제작에 있어서 도로 레이어를 구성하고 있는 교통안전표지 및 도로표지의 제작 공정에 있어서 딥러닝의 적용방안을 탐색하였다. 딥러닝의 이미지 분류에서 활용하는 전수학습을 이용하여 취득한 영상에 대한 학습자료 구축을 통해 도로 표지정보의 자동분류를 수행하였다. 분석결과 주의, 규제, 지시, 보조는 촬영된 이미지의 품질 및 형태 등 여러 가지 요소에 의해 정확도가 불규칙하게 나타났지만, 안내표지의 경우는 정확도가 97% 이상으로 높게 나타났다. 수치지도제작에 있어 전수학습을 이용한 이미지 자동분류 방식은 교통안전표지를 포함한 다양한 레이어들에 대한 자료 취득과 분류에 있어서 활용이 증가할 것으로 기대한다.

In this paper, we propose wavelet transform image compression method such that an image is decomposed into multiresolutions using biorthogonal wavelet transform with linear phase response property and decomposed subbands are classified by maximum classification gain. The classified data is quantized by allocating bits in accordance with classified class informations within subbands through arbitrary set bit allocation algorithm. And then, quantized data in each subband are entropy coded. The proposed coding method is that the quantized data perform shuffling before entropy coding in order to remove sign bit plane. And the context is assigned by maximum correlation direction for bit plane coding.

In this paper we propose an emotional expression method using a comic model and special marks for effective sign-language communications. Until now we have investigated to produce more realistic facial and emotional expression. When representing only emotional expression, however, a comic expression could be better than the real picture of a face. The comic face is a comic-style expression model in which almost components except the necessary parts like eyebrows, eyes, nose and mouth are discarded. In the comic model, we can use some special marks for the purpose of emphasizing various emotions. We represent emotional expression using Action Units(AU) of Facial Action Coding System(FACS) and define Special Unit(SU) for emphasizing the emotions. Experimental results show a possibility that the proposed method could be used efficiently for sign-language image communications.

The sign-language tan be used a9 an auxiliary communication means between avatars of different languages. At that time an intelligent communication method can be also utilized to achieve real-time communication, where intelligently coded data (joint angles for arm gestures and action units for facial emotions) are transmitted instead of real pictures. In this paper we design a gesture-emotion keyframe editor to provide the means to get easily the parameter values. To calculate both joint angles of the arms and the hands and to goner-ate the in keyframes realistically, a transformation matrix of inverse kinematics and some kinds of constraints are applied. Also, to edit emotional expressions efficiently, a comic-style facial model having only eyebrows, eyes nose, and mouth is employed. Experimental results show a possibility that the editor could be used for intelligent sign-language image communications between different lan-guages.
