In this study an economical image stitching algorithm for use in automotive industry is developed for retrofittable panoramic image assistance applications. The aim of this project is to develop a driving assistance system known as Panoramic Parking Assistance (PPA) which is cheap, retrofittable and compatible for every type of automobiles. PPA generates bird's eye view image using cameras installed on the automobiles. Image stitching requires to get bird's eye view position of the vehicle. Panoramic images are wide area images that cannot be available by taking one shot, attained by stitching the overlapping areas. To achieve correct stitching many algorithms are used. This study includes some type of these algorithms and presents a simple one that is economical and practical. Firstly, the mathematical model of a wide view of angle camera is provided. Then distorted image correction is performed. Stitching is implemented by using the SIFT and SURF algorithms. It has been seen that using such algorithms requires complex image processing knowledge and implementation of high quality digital processors, which would be impracticle and costly for automobile use. Thus a simpler algorithm has been developed to decrase the complexity. The proposed algorithm uses one matching point for every couple of images and has ease of use and does not need high power processors. To show the efficiency, images coming from four distinct cameras are stitched by using the algorithm developed for the study and usability for automotive application is analyzed.

한국의 대 베트남 교역 확대도 한국의 투자 증가에 기인하며 특히 한국으로부터 수입은 대부분 중간재로서 베트남의 수출과 고용에 크게 기여하고 있다. 최근 양국 정상은 2015년까지 교역액 200억 달러를 달성하기 위해 노력하기로 합의하기도 하였다(kotra.or.kr). 이처럼 한국과 베트남의 투자 및 교역의 증가는 계속되고 있는 상황에서 베트남에서 생산되는 제품이 한국 국내 시장에 계속 증가하여 베트남 제품에 대한 한국 소비자들의 인식 또한 점차 개선되고 있다고 볼 수 있다. 본 연구는 한국 소비자가 베트남 제품을 구매할 때, 베트남에 대한 국가 이미지 또는 베트남 제품에 대한 이미지가 베트남 제품을 구매할 때 어떠한 영향을 미칠 것인가에 대해 실증적으로 연구하고자 한다. 분석결과 베트남 정치적 이미지에 따른 베트남산 원산지 효과는 부정적으로 나타났다. 이는 베트남이 개방을 하였다하더라고 공산주의 체제를 유지하고 있기 때문이기도 하다. 그리고 또한 사회적 이미지가 원산지 효과에 미치는 영향도 부정적 효과를 가지고 있다. 그러나 문화적 이미지, 경제적 이미지, 국제적 이미지에 따른 베트남 원산지 효과는 유의하게 나타났다. 그리고 이와 같은 원산지 효과가 베트남 제품의 재구매 의도에도 유의하게 나타났음을 알 수 있다.

The purpose of this study was to make marketing strategies for Korean fashion companies that wish to enter into foreign markets. In-depth-interviews along with documentary research were performed on consumers who lived in Italy. The interviews were executed from May to December 2010. The results of research were as follows. The general image of Korea was at a high level. Therefore, the general and economical image of Korea had a significant impact on product evaluation. However, the Italian consumer had only a little understanding about the Korean fashion brand and product. This was so because the Korean fashion companies did not appear in the Italian fashion market. However, they were accustomed to using products of Samsung and LG. Therefore, the economical image of Korea is necessary to facilitate the official entrance of fashion companies in the Italian market as well as the global market.

The Electro-Optical Camera(EOC) image of the first Korea Multi-Purpose Satellitel(KOMPSAT-1) has both high resolution and convenient acquisition of research data, but on the other hand it has a defect of one band image. Fortunately, the multispectral Moderate Resolution Imaging Spectroradiometer (MODIS) image data are receiving every day at the Korea Aerospace Research Institute (KARI). Therefore, this paper performed an effective merging for survey of reclaimed land using the high-resolution (6.6m) KOMPSAT-1 EOC image and the multispectral MODIS image data. According this paper prepared map of reclaimed lands in Western Coast of North Korea as quantitative(position and form) survey of reclaimed lands of North Korea using merged image. The use of KOPSAT-1 EOC image and MODIS images was found to be economical such using of large scale areas as reclaimed land or according easy to collect information and such north korea as inaccessible areas like as receiving every day.

The purpose of this study is to find out the orientations and characteristic in clothes buying of each age group of elderly women, based on the actual self-image and the ideal self-image of clothing. Grasping the diversity of their clothes' buying orientations will be helpful in making a better merchandise production planning for apparel, and in launching new brands into the market. The study will also provide useful data in developing sales strategies which enable to supply goods that meet consumers' needs and tastes in the quality market, and consequently will help to classify the market. Samples were 488 women of 55 and over, dwelling in Pusan Metropolitan City. The data was analysed by using MANOVA, ANOVA, and the Cronbach's $\alpha$ reliability was also applied. The conclusions based on the theoretical background and the result of questionnaire surveys were as follows: 1. The order of priority of buying orientations based on clothes's actual self-image was 'practicality', 'cautiousness' and 'economical effectiveness' without regard to age. The items that showed the significant differences in 50's were 'cautiousness', 'experimentation', 'fashion-consciousness' and ostentatiouness, and in 70's were 'economical effectiveness', 'experimentation', 'impulsiveness' and 'environmental friendliness', and none in 60's. 2. The order of priority based on clothes' ideal self-image was the same as that of actual one, and there was no significant difference between age groups.

Generally, general-purpose image processing system is so expensive that not so many users easily can access the system. In this paper attemps have been made to design and describe a general and economical image processing system for real-time aplications such as image data compression, pattern recognition and target tracking. The system comprises an operator console, image data acquisition/display sistem and IBM PC/XT. The system also utilizes a high speed Fairchild 16-bit microprocessor with ALU speed of 375 nsec for system control, algrithm execution and user computation. The system also can digitize /display a 256x 256x 8 bit image in real time and store two frames of images. All image pixels are directly accessible by the microprocessor for fast and efficient computation. Some experimental and illustrative results such as target tracking are presented to show the efficient performance of the system.

The study was proposed to establish the effective color image planning and to suggest the color combination data for clothing through historic costume. To test the suggested method The Color Image Scale developed in Japan was adapted, For the practical study 21 fashion illustrations of Art Deco period (1910-1930) were selec-ted. Color images analysed from these illustrations were seleted with the key words extracted from political economical social background and art of Art Deco period. Three of the image categories clear modern and dynamic were sutable to express the images of this period. The image categories representing color image of Art Deco costume were dynamic modern classic, casual, clear, nature and gorgeous.

표면영상유속계(SIV)는 기존의 입자영상유속계(PIV)의 원리를 이용하여 하천의 표면유속을 측정하는 방법이다. 본 연구에서는 경제적이고 효율적인 유속측정 기법인 SIV 기법을 이용하여 국내 3개 하천에 대하여 현장 유량측정에 적용하였다. 현장 영상분석은 다중카메라 방식을 이용하였고 영상분석과정에 필요한 참조점과 횡단면 자료는 측량을 통하여 획득하였다. SIV로 측정된 유속을 검증하는 수로 실험의 결과, 평균오차 10% 이내의 정확도를 보여 정확한 유속측정이 가능함을 확인하였다. 그러나, 실제 하천에의 적용에서는 저수위시와 악천후시에 대해서는 20 % 이내의 오차를 보이는 것으로 나타났다. 향후 SIV 기법의 문제점들을 해결한다면 언제 어디서나 효율적이고 경제적인 유량측정을 할 수 있을 것이다. 그리고 이를 활용하여 실시간 하천정보시스템으로 발전시킴으로써 하천 관리에 큰 도움이 될 것이라 판단된다.
