Recently various studies on various applications using images taken by mobile phone cameras have been actively conducted. This study proposes a correction method for misrecognition of Korean Texts in signboard images using improved Levenshtein metric. The proposed method calculates distances of five recognized candidates and detects the best match texts from signboard text database. For verifying the efficiency of the proposed method, a database dictionary is built using 1.3 million words of nationwide signboard through removing duplicated words. We compared the proposed method to Levenshtein Metric which is one of representative text string comparison algorithms. As a result, the proposed method based on improved Levenshtein metric represents an improvement in recognition rates 31.5% on average compared to that of conventional methods.

In recent years research on HCI technology has been very active and speech recognition is being used as its typical method. Its recognition, however, is deteriorated with the increase of surrounding noise. To solve this problem, studies concerning the multimodal HCI are being briskly made. This paper describes automated lipreading for bimodal speech recognition on the basis of image- and speech information. It employs audio-visual DB containing 1,074 words from 70 voice and tri-viseme as a recognition unit, and state tied HMM as a recognition model. Performance of automated recognition of 22 to 1,000 words are evaluated to achieve word recognition of 60.5% in terms of 22word recognizer.

In this paper, I applied grounded theory in exploring how Twitter became the battlefield for China's public diplomacy campaign. China's new move to global social media platforms, such as Twitter and Facebook, has been a controversial strategy in public diplomacy. This study analyzes Chinese Foreign Spokesperson Zhao Lijian's Twitter posts and comments. It models China's recent diplomatic move to Twitter as a "war of words" model, with features including "leadership," "polarization," and "aggression," while exerting possible effects as "resistance," "hatred," and "sarcasm" to the global community. Our findings show that by failing to gage public opinion and promote the country's positive image, China's current digital diplomacy strategy reflected by Zhao Lijian's tweets has instead constructed a polarized political public sphere, contradictory to the country's promoted "shared human destiny." The "war of words" model extends our understanding of China's new digital diplomacy move as a hybrid of state propaganda and self-performance. Such a strategy could spread hate speech and accelerate political polarization in cyberspace, despite improvements to China's homogenous network building on Twitter.

The purpose of this study is to examine the concept of modern consumer society and to analyze how the meaning of postmodern-feminism is consumed into what image of preference in fashion. The function of modern society has changed into the system which is centered around consumption from the one that emphasizes labor and production of mass consumption age by mass production. In this consumer society, consumption means just not to waste of production but to consume the commodity sign reflected on the desire of a moderner. In other words, it means what is consumed will be the meaning, preference, symbol, and image mood not goods itself with physical feature. Existing feminism has affected by postmodernism. Due to that, postmodern-feminism has developed, taking to pieces the paternal argument since the late 1960s. It has tried to give up hope this idea, regarding sex distinction as a socially organized category contrary to women's identity of biological aspect suppressed in the paternal system of value. Especially it has demanded only one type on sex should be translated into a distinctive quality, multiple meaning, and sex. Accordingly in modern fashion, this aspect is expressed like the followings : distinction into women's image evaded fixation, multiple meaning into image of androgyny, multiple sex into that of mixture. And this is used as the image of symbolic goods, also the purpose of brand difference.

Customer-Orientation can be referred to as the concept of creating and maintaining a superior value within the market by responding to the 'wants of the customer' in regards to the Hotel. In other words, customer-orienated hotel is forcasting a customer' response to being different from other competitors, competing with others, and winning in the market. Therefore, hotels exert their efforts in various customer-oriented activities which may result in customer satisfaction. The pruposes of this study are to find out various significant factors impinging on customer-orientation and service image in hotels. For these purposes, two hypothesis were established, and the samples of this study were 15 hotels in Pusan, KyeongJu. The verification of the proposed hypothesis showed the following results: First, service quality and customer-orientation were found to be significantly related. In detail, the employees of hotel were shown to be affected in sales management, human relationship and service quality. Second, customer-orientation and service image were found to be significantly related. namely, the customer-orientation of hotel' employee were found to be significantly related with hotel service image. The research results and suggestions of this study are as follows: First, it is necessary that provide better service/product to satisfy the customers. Second, it is necessary that the employees of tourist hotel try to resolve the complaint of customers. Third, it is necessary that the employees of hotel try to improve the image as good service.

In this paper, we present tracking algorithm for the indoor moving object. We research passive method using a camera and image processing. It had been researched to use dynamic based estimators, such as Kalman Filter, Extended Kalman Filter and Particle Filter for tracking moving object. These algorithm have a good performance on real-time tracking, but they have a limit. If the shape of object is changed or object is located on complex background, they will fail to track them. This problem will need the complicated image processing algorithm. Finally, a large algorithm is made from integration of dynamic based estimator and image processing algorithm. For eliminating this inefficiency problem, image based estimator, Mean-shift Algorithm is suggested. This algorithm is implemented by color histogram. In other words, it decide coordinate of object's center from using probability density of histogram in image. Although shape is changed, this is not disturbed by complex background and can track object. This paper shows the results in real camera system, and decides 3D coordinate using the data from mean-shift algorithm and relationship of real frame and camera frame.

The goal of this paper is accuracy improvement of appearance inspection by using image separation average value matching method. The appearance inspection of various electronic products and parts has been executed by the eyesight of human. But inspection by eyesight can't bring about uniform inspection result. Because the appearance inspection result by eyesight of human is changed by condition of physical and spirit of the checker. So machine vision inspection system is currently used to many appearance inspection fields instead of the checker. However the inspection result of machine vision is changed by the illumination of workplace. Therefore we have used a average value matching in this paper for improvement of vision inspection accuracy and could increase inspection accuracy of vision system. In other words, we made an effort for elevation of vision inspection accuracy by making the identical image separation average value of reference image and input image. Also this system has been developed only using PC, CCD Camera and Visual C++ for universal workplace.
