In this paper. a way to analysis a corridor scene for a vehicle's automatic locomotion is presented In general, it's necessary for a vision system of vehicles to identify its positions in given environments. The suggested algorithm is to decide base lines of a corridor image using the vanishing point finding. Feature points are extracted on the base line using a base line extraction tree. This algorithm is suitable for a motorized wheelchair's self locomotion in a building.

In this paper, color coordinate system transformation based visual servo controller has been considered. Mobile robot always has a position error and an orientation error resulted from wheel slipping etc.. Even more, the errors have accumulative properties. So feedback from environments is important. In this paper, by using color model faster land mark extraction can be achieved. And the global position and the orientation of mobile robot can be known by only two land marks positions in image coordinate system. Finally, the adoption of visual information in path tracking problem makes visual servo control.

A survey on images and consumption for instant food for 419 housewives in Kyung-ki do were summarized as follows: 1) The thought of housewives takes 'convenient' as the best advantage in the image on instant food, generally speaking,'preference', 'hygienic concern' and 'eating frequently’ are moderate, while 'good for health' is shown with the lowest points. 2) The reasons why they take instant food are ascribed to the taste of the children by 63.6%, to 'convenient to cook' by 19.6%. 3) The reasons why they do not use instant food are attributed to 'bad for health’by 46.9% to 'too expensive' by 29.9%, and to 'doubtful in quality' by 16.3% 4) Instant noodle (Ramyun) and bread are consumed the most, and then consumption is shown from high to low in order of tomato-ketchup, ham, mayonnaise, instant liver and sausage. 5) Effects on purchasing instant food come from the date of manufacturing 43%, trade mark 24% the experience of previous use as high as 21.2%.

This paper describe an interactive video object segmentation tool which can be used to generate MPEG-4 video object planes for multimedia broadcasting and enables content based functionalities. In order to apply these functionalities, each frame of video sequence should be represented in terms of video objects. Semiautomatic segmentation can be thought of as a user-assisted segmentation technique. A user can initially mark objects of interest around the real object boundaries. Then the user-guided and selected objects are continuously separated from the unselected areas though time evolution in the image sequences. We proposed method shows very promising result and this encourages the development of object based video editing system.

The purpose of this study is to identify in two aspects the relationship between standardization activities and technological development at the firm level. The first aspect is to analyze the relationship between the current Korean industrial standards system and the firm's technological development vis-a-vis quality standards. The analysis reveals that even if Korean firms recognize the importance of standards, the level of product quality of the KS mark is still lower compared to the average world level. The survey also reveals that the reasons for acquiring ISO and KS marks are mainly aimed at enforcing company image and increasing quality management mind, rather than to foster technological innovation. The second aspect explores how much Korean industrial standards (KS marks) affect the firm's technological development in the Process of standards acquisition activities. The survey results show that standardization activities have a less positive impact on technological innovation than on the maintenance of consistent production works.

This paper aims to draw out the practical lessons for City Brand as aspect of urban spatial by urban regeneration project in Korea. Image of the City and City Brand is the most important element for the competitiveness of modern cities. This paper discusses the guide line or strategy of City Brand, its current status in Korea. It also examines the present Urban Regeneration in Korea, identifies the problems encountered in implementation, and suggests the solutions for strengthening urban competitiveness such as a City Brand. Also it emphasized that well planned invisible and physical environments, including story and land-mark facilities, are also crucial in making City Brand more attractive and competitive.

As part of effort to reduce the process time from design to manufacture and delivery, the concept of CE(concurrent engineering) has been applied to design process. In this research, the drawing information management system (DIMS) was developed based on CE. The system can distribute electronic documents of drawing or work instruction parallel to all reviewers simultaneously and collect their annotations through network. Mark-up functions are used for annotations on the electronic documents. DIMS is a system which integrates drawing management, engineering BOM, CAD and raster drawings, etc. In this system, a SUN workstation is interfaced with PCs by LAN. CIMCAD-2D, Image Hunter, and ORACLE RDBMS are used for CAD drawings, raster drawings, and drawing information management, respectively. As an integration tool for all the information, LINKAGE is adopted.

We present a new method for an automated markerless system to describe, analyze, and classify human gait motion. The automated system consists of three stages: I) detection and extraction of the moving human body and its contour from image sequences, ii) extraction of gait figures by the joint angles and body points, and iii) analysis of motion parameters and feature extraction for classifying human gait. A sequential set of 2D stick figures is used to represent the human gait motion, and the features based on motion parameters are determined from the sequence of extracted gait figures. Then, a k-nearest neighbor classifier is used to classify the gait patterns. In experiments, this provides an alternative estimate of biomechanical parameters on a large population of subjects, suggesting that the estimate of variance by marker-based techniques appeared generous. This is a very effective and well-defined representation method for analyzing the gait motion. As such, the markerless approach confirms uniqueness of the gait as earlier studies and encourages further development along these lines.

A service robot is expected to be useful in indoor environment such as a hotel, a hospital and so on. However, many service robots are driven by wheels so that they cannot climb stairs to move to other floors. If the robot cannot use elevators. In this paper, the mobile manipulator system was developed, which can operate numeral buttons on the operating panel in the elevator. To perform this task, the robot is composed of an image recognition module, an ultrasonic sensor module and a manipulator. The robot can recognize numeral buttons and an end-effector in manipulator by the vision system. The Learning vector quantization (LVQ) algorithm is used to recognize the number on the button. The barcode mark on the end-effector is used to recognize the end-effector. The manipulator can push numeral buttons using informations captured by the vision system. The proposed method is evaluated by experiments.
