  • In this paper, we directly implemented the Line Tracer ROS package that can detect and follow lines drawn on the map on Gazebo, an open-source that is widely used in autonomous driving research. For line detection, the cv_bridge package was used to enable OpenCV's image processing tools, and parameters such as robot speed, line color and ground material could be changed. In addition, proportional (P) and PID controls could be implemented using the color centroid obtained through image processing. Through this approach, the effect of proportional and differential coefficients on the robot's line tracer motion could be analyzed effectively. In addition, by displaying robot simulation results using various tools of ROS, an efficient development for control nodes could be established in ROS.

  • The design concept of this dental clinic Interior design is emotional color expression for the medical facility. This dental clinic is showing off the new adoption of the Korean primary traditional color pallette for the medical interior design. The graphic wall of the corridor is strongly attracting the eyes of customers while wrapping the corridor wall and partition with rather unconventional primary colored graphic shaping a tooth. Also the vivid and the dynamic atmosphere are emphasized by using the red color in the treatment area and the powder room. For the space programing, I focused on the functionality of each space and the efficiency of the traffic line. Centering around the information desk, the principal traffic line Is divided Into the staffs' private movement and the public movement.

  • An integrated on-line inspection system was constructed with seven cameras, half mirrors to split images, 720 nm and 970 nm band pass filters, illumination chamber having several tungsten-halogen lamps, one main computer, one color frame grabber, two 4-channel multiplexors, and flat plate conveyer, etc., so that a total of seven images, that is, one color image from the top side of an apple and two B/W images from each side (top, right and left) could be captured and displayed on a computer monitor through the multiplexor. One of the two B/W images captured from each side is 720nm filter image and the other is 970nm. With this system an on-line grading software was developed to evaluate appearance quality. On-line test results to the Fuji apples that were manually fed on the conveyer showed that grading accuracies of the color, defective and shape were 95.3%, 86% and 91%, respectively. Grading time was 0.35 sec per apple on an average. Therefore, this on-line grading system could be used for inspection of the final products produced from an apple sorting system.

On-line test results with Fuji apples that were manually fed on the conveyer showed that grading accuracies of the color, defect and shape were 95.3%, 86% and 88.6%, respectively. Grading time was 0.35 second per apple on an average. Therefore, this on-line grading system could be used for inspection of the final products produced from an apple sorting system.

  • The social and psychological approaches to clothing researches by Fluge,l, Hurlock and Barr in the early 1930's have since been developed greatly. It has now been generally agreed that clothing is the symbol of one's personality and social status, for clothing is regarded as the second skin and a manifestation of one's emotional states as well. Based on this consensus, this study was intended to observe the possible relationship between one's clothing design preference-in line, color and texture- and interest. For this survey, 200 college woman students from four universities were selected at random, and an interest-test standardized by prof. Jung Bum Mo and a questionaire made of 20 items on the clothing prferences were given. The results as commputerized and analyzed are as follows : 1. Line Preference a) Structural line : It is quite obvious that those like straight line are interested in fine arts, and curved line in physics. b) Out-line : Among tubular, bell and bustle of the silhouette, those like the bustle have shown particular interest in music, and the tubular in politics and business. c) Style : There is a salient tendency that those like a dressy style are much interested in music, and casual style in physics and physical exercise. 2. Color Preference a) Favorite color : Those like red, orange and yellow show a high interest in artistic activities and physical exercise, and black, grey and white in politics. b) Variety and combination of color ; These have shown no relationship to the interest. 3. Texture Preference a) The touch : Those like the texture with the feeling the crisp and rough are interested in fine arts, and of soft and smooth in the field of social service. b) Fabric surface : Those like naturalistic pattern, i.e. print of flowers, show much interest in music and literature, and plain fabrics in physical exercise.

  • RGB 조건에서 하나의 픽셀은 255의 세제곱 개 이상의 색상을 표현할 수 있다. 현재까지의 컴퓨터 비전 연구는 조류에서 나타나는 다양한 깃털색 표현형에 대해 세밀히 분석하여 종을 구분하였지만, GWAS에 이용될 목적을 위해 다양하게 유전되는 색상을 단순화하지 못하였다고 판단된다. 본 연구는 연산오계(YO)와 백색레그혼(WL) 상호역교배 F2 집단을 이용하였으며 이미지 양자화를 통하여 이미지의 크기를 줄이고 저장을 용이하게 하였으며 깃털색의 원인 유전자 탐색을 위한 기초 자료를 제공하기 위하여 육안으로 결정하였던 다양한 깃털색을 단순화하였다. 특히, GWAS 연구에 필요한 수치화된 표현형을 제시하였다는 측면에서 가치가 있다고 판단된다.

  • This thesis, concerning Femme Fatale Images Costume Form in paintings viewed from DeLong's Theory, analyzed frequency and traits on the basis of DeLong's Form Observation Theory and drew out the result as followings. First, Costume Form was mostly open, whole, planer integration, rounded, and indeterminate. The styles were similar each other. Second, surface structure was expressed by line & shape, color, texture, and pattern of which color had the highest priority. Next, line & shape and texture had the priority in order. They were expressed through intereaction. Third, the traits of Costume Form were a similar color harmony or large light and darkness contrast+soft quality+interaction by ambiguous line & shape. So, Femme Fatale Image in paintings was expressed by soft and pure images and erotic images.

  • 색선(Color line)은 물체의 색을 표현하는 방법으로 단색인 물체의 색은 하나의 색선으 표현된다는 것이다. 하이라이트가 발생하는 반짝이는 물체는 색선이 하이라이트를 포함하기 때문에 하이라이트를 찾고 하이라이트에서 영역을 확장하면서 색선을 생성할 수 있다. 그러나 단순한 영역확장방법은 색을 구분이 난해하기 때문에 제한적인 영역확장 방법을 사용해야 한다. 여기서 노출 시간이 다른 이미지를 한 장 더 촬영하여 하이라이트의 색상 방향을 설정하고 이를 기반으로 색선을 생성한다. 본 연구에서는 하이라이트 기반으로 색선을 생성하고 생성된 색선을 이용하여 반짝이는 특성도 제거한 후 결과를 비교한다.

  • 본 논문에서는 프로젝션 프로파일(PP: Projection Profile) 과 컬러공간변환(CST: Color Space Transform)을 이용하여 라인스캔 카메라(Line-Scan Camera) 영상을 재구성함으로써 LCD 표면의 결함검출 성능을 높이는 알고리즘을 제안하였다. 제안된 알고리즘은 결함을 포함한 RGB 영역 분할, 대표값 추적시스템을 이용한 대표값 추출, 그리고 컬러공간변환을 이용한 Y영상 재구성 방법들로 구성되어 있다. 실험을 통하여 제안한 방법으로 재구성된 영상의 결함검출 성능이 영역카메라(Aerial Camera)의 결함검출 성능보다 우수함을 보였다.

  • The purpose of this study was to investigate the effect of the depth of fashion product line on sales. The depth of the fashion product line was defined as the variety of style, color, and size in the outwear line for this study. Data were collected from the 98 brands in 4 department stores located in Seoul and Pusan. The result showed the significant impact of the variety of the outwear style on sales. Even after controlling the effect of advertising and the level of price in each brand, significant effect of the variety of outwear style were noticed on sales.
