  • Road signs are guide facilities for road users, and the Ministry of Land, Infrastructure and Transport has established and operated a system to enhance the convenience of managing these road signs. The role of road signs will decrease in the future autonomous driving, but they will continue to be needed. For the accurate mechanical recognition of texts on road signs, automatic road sign recognition equipment has been developed and it has applied image-based text recognition technology. Yet there are many cases of misrecognition due to irregular specifications and external environmental factors such as manual manufacturing, illumination, light reflection, and rainfall. The purpose of this study is to derive location-based destination names for finding misrecognition errors that cannot be overcome by image analysis, and to improve the automatic recognition of road signs destination names by using Levenshtein similarity verification method based on phoneme separation.

  • Lenses with an ultra wide angle of view are usually called fisheye lenses since a fish can see an ultra wide panoramic view under water. As the angle of view for these kinds of lenses reaches a wide angle, the illumination on an image sensor is reduced by a rapid drop. In this paper, we discuss the causes and the ways to correct for a rapid drop. First, it is treated for the sign convention of directional cosine vectors and normal vectors on the curved surface by means of analytic geometry. And, from the fundamental discussion for these vectors, the rapid illumination drop is numerically analyzed for various kinds of causes by utilizing geometrical optics and radiometry as well as Fresnel equations derived from electromagnetic boundary conditions. As a result, we are able to get the full understanding for the rapid illumination drop and to propose ways to correct effects due to an wide angle of view.

  • The finger language is the part of the sign language, which is a language system that expresses vowels and consonants with hand gestures. Korean finger language has 31 gestures and each of them needs a lot of learning models for accurate recognition. If there exist mass learning models, it spends a lot of time to search. So a real-time awareness system concentrates on how to reduce search spaces. For solving these problems, this paper suggest a hierarchy HMM structure that reduces the exploration space effectively without decreasing recognition rate. The Korean finger language is divided into 3 categories according to the direction of a wrist, and a model can be searched within these categories. Pre-classification can discern a similar finger Korean language. And it makes a search space to be managed effectively. Therefore the proposed method can be applied on the real-time recognition system. Experimental results demonstrate that the proposed method can reduce the time about three times than general HMM recognition method.

  • Advertisements create the illusion about the ideal body utilizing body beauty as well as come to influence in formation of the social beauty standard. Commodity advertisements using the body have been considered as the most effective advertisement method because of the fluidity and the dynamic, which are understood as organic body's characteristics. Especially, advertisement strategies utilizing body painting draw customer's attention because of the properties liberally performed on the living body. This thesis attends to study on the J. Deleuze's 'becoming' Phenomenon expressed in body painting, and to analyze about the body becomes fashion and commodity and is positively utilized as effective advertisement tools. J. Deleuze's 'becoming' Phenomenon expressed in advertisement utilized body which painting is classified as follows as; becoming fashion of the body, becoming commodity of the body, becoming advertisement sign board of the body, becoming animals and plants of the body, and becoming image of the body. The result of this study on the J. Deleuze's 'becoming' Phenomenon expressed in advertisements utilizing body painting shows multiple commodity's characteristics in order to satisfy with customer's various anxieties being changed continuously, and represents the characteristics of 21C advertisements utilizing the body being changed any other thing. Consequently, this thesis is aimed at new consideration about the body beauty, which has been extended to other sphere.

  • This study analyzed the attention concentration tendencies of one(1) subject who showed convergent exploratory acts actively through the gaze-brainwave measurement experiment of cafe space images and our research findings are as follows. First, the areas of interest (AOIs) that the subject gazed visually by paying attention to it and concentrating on it at a cafe space include counter&menu area, sign area, partition area, image wall area, stairs area, and movable furniture area, and built-in furniture area: seven areas in total. Second, conscious gaze frequency appeared the highest in counter&menu area, and conscious gaze appeared more later than in initial times. Third, conscious gaze pattern was divided into the zone that explored various areas dispersely (distributed exploratory zone) and the zone that explored between particular areas concentratedly (intensive exploratory zone). Fourth, as a result of analyzing the brainwave attention concentration, it was found that the attention concentration in prefrontal lobe (Fp1, Fp2) and frontal lobe (F3, F4) rose to a higher level in the zone of 15 to 16 seconds and this time zone was considered to be a zone where gazing at counter&menu area was very active. In addition, the attention concentration appeared higher in the initial zone than in the later zone, among the entire experimental time zones. Finally, as a result of analyzing the changes in activation by brain portion of the SMR wave expressed when maintaining the arousal and attention concentration, it was found that the right prefrontal lobe and the frontal lobe became activated in the time zone when the intensive exploration of "counter&menu area" and "movable furniture${\leftrightarrow}$built-in furniture area" had occurred and the time zone when the intensive exploration of "image wall${\leftrightarrow}$partition area" and "counter&menu${\leftrightarrow}$sign area" had occurred.

  • Typography is the combination of language of formative art. It is indeed the core means of human communication through understanding of language and formative values. Studies began on introduction of various techniques to overcome the phenomenon of the 'reaction of language', which appears as an impediment in delivery and sharing of information as the most fundamental roles. Successively, mobile printing types more readable and effective in delivering of meanings have been developed, thus widely distributed for general use. However, although such printing types might be easily used in image and digital media, such as in computer monitors, screens and mobile phone LCDs, etc., it is in fact difficult to use these printing types in printed surfaces, the traditional medium of information delivery, or in sign systems frequently encountered in our surrounding environment. As a solution for this, it is intended to create an effect of communication closer to dynamic typography expression by approaching visual message delivery system from the essence and substance of the color application, which corresponds to the visual spatial expression effect, the core element of expression in dynamic typography to possess significantly more powerful effect in terms of both message delivery capacity and readability than the conventional means of static typography.

  • In this paper, we present Emergency exit signs are installed to provide escape routes or ways in buildings like shopping malls, hospitals, industry, and government complex, etc. and various other places for safety purpose to aid people to escape easily during emergency situations. In case of an emergency situation like smoke, fire, bad lightings and crowded stamped condition at emergency situations, it's difficult for people to recognize the emergency exit signs and emergency doors to exit from the emergency building areas. This paper propose an automatic emergency exit sing recognition to find exit direction using a smart device. The proposed approach aims to develop an computer vision based smart phone application to detect emergency exit signs using the smart device camera and guide the direction to escape in the visible and audible output format. In this research, a CAMShift object tracking approach is used to detect the emergency exit sign and the direction information extracted using template matching method. The direction information of the exit sign is stored in a text format and then using text-to-speech the text synthesized to audible acoustic signal. The synthesized acoustic signal render on smart device speaker as an escape guide information to the user. This research result is analyzed and concluded from the views of visual elements selecting, EXIT appearance design and EXIT's placement in the building, which is very valuable and can be commonly referred in wayfinder system.

  • Road signs are part of the traffic facilities intended to guide drivers to their destinations in a safe and comfortable manner. Due to the creation of new routes, changes to the old routes, and the deterioration of road signs, road signs do require efforts to do ongoing field investigations and put the results in a database. The purpose of this study was to propose methodologies to do field investigations and build a database for road signs efficiently. For that purpose, a mobile mapping system was designed for field investigations. The designed mobile mapping system was comprised of three cameras to produce image information about road signs, GPS/IMU/DMI to obtain information about the position and attitude of a vehicle, and a laser scanner to generate information about the locations of road signs and routes. Also proposed in the study was a procedure to automatically detect the areas of road signs in the road signs images and recognize their characters.

  • Information is the most important rather then wealth in the information age. According to propagation of the information by new media, this era is called communication innovation age. And away of thought and life style as well as a society system are changing. Propagation by newspaper and TV as well as new media makes new view on value of consumers, and they recognize propensity to consume as needs from emotion rather than economical value. Changes of thoughts make lots of innovation:from one side, modern design to multi-meanimg design, from consuming of products to consuming of the image, from outer object to inner object, from consuming by mass to consuming individually by fashion. It means the possibilities that a meaning could be interpreted variously. Sign is a configuration for communication with discourse, which is the communication between meaning maker and meaning solver. In this study, various expression of sign in advertising were divided into direct expression and metaphoritical expression which was analysed deeply because it was recoquized as proper expression methed in postmodem design.

  • Body has been high-lightened as one of the most important theme since the philosophy and the arts are focused on it in the late 20th century. It would be of worth to study the characteristics of contemporary fiber-art works, especially done by Abakanowiz who has been regarded as a dominant pioneer in the contemporary fiber-arts from the viewpoint of inter-grade of the physicals and the mental. This paper, therefore, deals with the Abaknowiz' works in the context of human body and body-signs. Life and works might be classified into 5 stages: first, learning period since her birth in 1930, second, creation period of Abakans, third, remodelling period of Abakans, fourth, composition and dissolution period of Abakans and the last and fifth, new transformation period of Abakans. 'Abakans' through her whole life as an artist have been a plastic language and based ultimately on external human body but in various materials and forms. Abakan as a human-sign uses the past experiences and the texts of the other world in mixed and overlapped forms. Life-size Abakans by Abaknowiz can be easily understood as Abakanowiz herself and her Polish ancestor at the same time. The neuter Abakans with mashed face and obscure body is a expressive figure of coexisting world with opposite concepts like war and ideology, anxiety and freedom, man and woman, and etc. Human body as body-sign is an extensive image has existed since our forefathers and overlapped with the inter textual and the popular images. 'Abakans' that is our world and inner-self at the same time might be a window through which she tries to show what the world is.
