The color-based vision systems have been used to recognize our team robots, the opponent team robots and a ball in the robot soccer system. The color-based vision systems have the difficulty in that they are very sensitive to color variations brought by brightness changes. In this paper, a neural network trained with data obtained from various illumination conditions is used to classify colors in the modified YUV color space for the robot soccer vision system. For this, a new method to measure brightness is proposed by use of a color card. After the neural network is constructed, a look-up-table is generated to replace the neural network in order to reduce the computation time. Experimental results show that the proposed color classification method is robust under illumination variations.

In this paper, we propose a design and development of instructional cards to understand the grammar of coding, solving the problems and extending the computational thinking in the robot-driven environment. First, we designed the input/output module of the robot to process the coding grammar through the function analysis of the robot. And we designed the module of command card to learn coding grammar using color sensors. We have proven the validity of the designed instruction card by examining the experts to see if it is suitable for coding grammar learning. Designed robot and command card were developed with 28 cards and sensor robot. After applying the developed robot and command card to the elementary school students, the questionnaire showed that students grow the understanding and confidence of coding. In addition, students showed an increased need for programming learning.

신용카드 소지자들은 카드결제수단용을 넘어 본인을 나타내는 심리가 높아지고 있다. 이에 본 연구는 30, 40대 전업주부가 신용카드를 발급할 때 어떤 디자인 요소가 영향을 미치는지 알아보는 것이 목적이다. 신용카드를 사용하는 고객 중 연구 대상자를 서울과 수도권에 거주하는 30, 40대 주부 총 200명을 선정하여 국내 신용카드가 가지고 있는 디자인요소가 신용카드 선택에 어떤 영향을 미치는지 카드사 자료와 참고문헌, 선행연구를 토대로 설문지를 작성하여 설문조사를 하였다. 설문조사 결과 신용카드 디자인 요소 중 색상은 무채색 계열과 메인 이미지는 이미지나, 로고를 강조하지 않고 컬러로만 사용한 단순한 디자인을 가장 선호했고 다음으로 캐릭터형을 선호한 것으로 나타났다. 그리고 카드 장식은 없는 것을 선호하며, 금속 느낌의 카드 재질을 가장 선호하는 것을 알 수 있었다. 이를 통해 카드사에서 30, 40대 주부를 대상으로 하는 디자인 개발 시 방향을 제시하고자 한다.

This research designed usable standard color chart which was planned by hue and tone color system. This research studied 5 types standard color chart by designed tone map and preceding research. "Basic Color Chart 14 Colors" was planned for kindergarteners. "Primary Color Chart 63 Colors" was planned for schoolboys. "Middle Grade Color Chart 114 Colors" was planned for junior high school students. "High Grade Color Chart 152 Colors" was planned for senior high school students. "Hue and Tone 205 Colors" was planned for university students and general publics. These 5 types standard color chart were produced the trial color coordinate card and attached the Munsell notation which could reappear the spare color paper when needed. These 5 types standard color chart would be offered the data base for efficient color coordinate education as school age.

Most people are using a Color-CCD-Camera in other to acquire a color image. But we are getting a color image with the Monochrome-CCD-Camera equipped for Rotation-Color-Filter in front of the camera lens. The Monochrome CCD Camera has some advantages such as the low price. In addition Rotation-Color-Filter's design is very simple. So we can make this structure easily and economically. In this paper, we described how to make a color image from Monocrome-Camera and correcting color well.

A face recognition is currently the field which many research have been processed actively. But many problems must be solved the previous problem. First, We must recognize the face of the object taking a location various lighting change and change of the camera into account. In this paper, we proposed that new method to find feature within fast and correct computation time after scanning PC camera and ID card picture. It converted RGB color space to YUV. A face skin color extracts which equalize a histogram of Y ingredient without the Luminance. After, the method use V' ingredient which transforms V ingredient of YUV and then find the face feature. The result of the experiment shows getting correct input face image from ID Card picture and camera.

A new dual loop controller using color LCD bar graphs with LED back lights has been developed. An optional memory card is used to load or save the controller configuration, which may be a preprogrammed standard package or a user-programmed configuration, in addition to the built-in functions ready for user selection. The bar-graph display is selectable for single-loop or dual-loop use. A high grade of self-tuning functions using a modeling technique is built-in as standard. The controller can accommodate optional plug-in modules for thermocouples, communication, etc. All the options are fully field upgradable.

The PID control to the monitor color correction was applied. Converted Gamma LUT was applied to the video card. Color and brightness information from the PID controller was used as control inputs. Color and brightness information from a calibrated monitor is measured again. Then, the difference between the preset values for the PID controller was compensated by the feedback. The software measured by color meter was used for color and brightness information. All of the monitor does not measure the color and brightness was measured by sampling. The color and brightness from the monitor were measured not by complete enumeration but by sampling. In the experiment, the original image was displayed on the same monitor as well as two other brands, and then, Gamma and Contrast were measured and compared.

In The White Card (2019), Claudia Rankine dramatically interrogates whiteness's persistent, reflexive habit of trying to preserve a state of innocence, expressing her vision of how this tendency blinds white liberal subjectivity to the structural reality of institutionalized racism in America. Rankine's exposure of the invisibility to which people of color are usually consigned by American whiteness is inseparable from her critical interrogation of how the hypervisibility of victims of racial violence provides white liberal subjectivity opportunities to intervene and feel good about itself. What Rankine enacts in the play is a process of repetition and revision, signifyin(g) on racial violence and its history; acts of racial violence continue to accrete, and her act of signifyin(g) on the countless acts of racial violence in America conveys the understanding that this text cannot be rewritten if white America continues to attend solely to individual, ostensibly isolated, acts of racial injustice.

The IMAPRO sotfware package was mainly focused to provide an algorithm which is capable of displaying various color composite images on IBM PC, VGA(Video Graphic Array) card with no special hardware. It displays the false color images using a low-cost eight-bit place refresh buffer. This produces similar quality to the one obtained from image board with three eight-bit plane. Also, it provides user friendly menu driven method for the user who are not familier with technical knowladge of image processing. It may prove useful for universities, institute and private company where expensive hardware is not available.
