In landscape simulatin, it is necessary to express very realistic image generated by computer graphics. One solution is to use texture mapping; however, it needs a lot of work and time to obtain images for texture mapping since there are huge variety of images for buildings, roads, stations and so on, and the landscape image is diverse due to the weather and time. Especially, weathered images such as stain on walls, crack on roads and so forth, are needed to make the landscape image very realistic. These weathered images do not have to be strict so that it saves a lot of work and time for obtaining the images for texture mapping if we can generate a variety of weathered images automatically. Therefore, this paper describes how to generate a variety of weathered images automatically by changing the weathered shape of the original image.

Recently ARM processor's processing power has been increasing rapidly as it has been applied to consumer electronics products. Because of its computing power and low power consumption, it is used to various embedded systems.( including vision processing systems.) Embedded linux that provides well-made platform and GUI is also a powerful tool for ARM based embedded systems. So short period to develop is one of major advantages to the ARM based embedded system. However, for real-time date processing applications such as an image processing system, ARM needs additional equipments such as FPGA that is suitable to parallel processing applications. In this paper, we developed an embedded system using ARM processor and FPGA. FPGA takes time consuming image preprocessing and numerical algorithms needs floating point arithmetic and user interface are implemented using the ARM processor. Overall processing speed of the system is 60 frames/sec of VGA images.

Private brands play an important role in formulating the marketing strategies of fashion goods. Merchandisers of Korean department stores are now realizing that the effective marketing of private brands can increase customers store loyalty as well as store profitability. Thus, it is important to better understand customer's decision making processes underlying the purchase of private brand apparels. However, Little research had been undertaken to examine integrated factors influencing purchases of private brand apparel. Therefore, the objective of this study is to propose a model of purchasing intentions of private brand apparel. This study pays attention to (1) perceived value, (2) familarity, (3) store image, (4) differenciated needs, (5) perceived risk, and (6) perceived quality variation of private brand. The proposed model supports all hypotheses presented in the paper. Purchase intentions of private brand increased as perceived money, familiarity, positive store image of private brands, and satisfaction of individuals differentiated needs increase. Furthermore, perceive value of private brand increased as perceived risk and quality variation of private brand increased.

This paper introduces a methodology of active calibration of a camera pose (orientation and position) using the images of cylindrical objects that are going to be manipulated. This active calibration method is different from the passive calibration where a specific pattern needs to be located at a certain position. In the active calibration, a camera attached on the robot captures images of objects that are going to be manipulated. That is, the prespecified position and orientation data of the cylindrical object are transformed into the camera pose through the two consecutive image frames. An ellipse can be extracted from each image frame, which is defined as a circular-feature matrix. Therefore, two circular-feature matrices and motion parameters between the two ellipses are enough for the active calibration process. This active calibration scheme is very effective for the precise control of a mobile/task robot that needs to be calibrated dynamically. To verify the effectiveness of active calibration, fundamental experiments are peformed.

This paper proposes illumination-efficient iris image capturing method. face capture method for extraction of iris pattern with one high resolution camera needs a large scale near infrared illumination. we replace high-resolution camera with co-optic-axial combination between wide view camera and narrow view camera. because this method needs small scale illumination that illuminate only narrow camera viewing angle, we can capture iris pattern image with small scale near infrared illumination.

This research aims at the development of Korean fashion design for the world market, which combines the western beauty and Korean tradition into the product design focusing on the styling concept. Through the example-analysis of structural elements which form Europe and Korean fashions, the styling concepts of functional change, beauty-combination, and tradition-conservation. are derived. The results are as follows : 1. Functionality needs to be improved by the structural change and the development of new materials from the traditional materials. 2. Beauty should come from the combination of natural patterns and western-spatial allocation, as well as from the front combination of western-beauty. 3. Tradition needs to be kept as Korean beauty and representation skills in the colors, accessaries, and in the spatial design. The styling concept for Korean fashion design in this research is related to the visual structural elements, and is not expanded to the styling concept of Korean image and/or feeling. Therefore future researches may follow on these un-expanded points. and also may continue the wide comparison between the Korean fashion design and oriental image fashion in Europe.

Regarding urban design in this 21st century, cities pursue human-oriented urban design through which nature, cities, and human beings are unified and interact with one another. For such urban design maintenance, it is needed to conduct systematic analysis and synthesis on various and complex factors of cities expressing urban images. Also, it is necessary to secure methods to evaluate those cities based on urban users' visual information. Thereupon, this study aims to suggest urban design evaluation methods which accept human behavior or needs and also allow us to figure out desirable images. For this, the study established the construction system of the most basic urban design components that form cities through literature review and expert evaluation. And it examines correlation among those factors with statistic means. Through this, the study suggests a new urban design evaluation system and evaluation process divided into experts and users so as to reflect user behavior or needs.
