  • 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.

  • 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.

  • Surface Image Velocity (SIV) is a technique which measures the surface velocity of river by using the principle of Paticle Image Velocimetry (PIV). The technique is economical and efficient way to measure velocity in rivers. The present paper aims to apply the technique to three rivers in Korea. It uses pairs of river surface images taken with two digital-cameras and reference points and cross section data which were acquired through plane survey. The performance of SIV was verified with automatic cart on an experimental flume. The test revealed that average error was less than 10 %, which assures that SIV can be used to measure velocity accurately. When it was applied to rivers with low water levels or rough weather condition, however, it showed the error about 20 %. If the problems of SIV technique are settled down, it can be one of the most convenient and economical ways to measure water discharge anytime and anywhere. And then it would be helpful to river management as developing a real-time river information system.
