This paper presents a fuzzy-based method for classification skin color object in a complex background under varying illumination. Parameters of fuzzy rule base are generated using a genetic algorithm(GA). The color model is used in the YCbCr color space. We propose a unique fuzzy system in order to accommodate varying background color and illumination condition. This fuzzy system approach to skin color classification is discussed along with an overview of YCbCr color space.

The objective of this paper is to provide an automatic color image testing system capable of synthetically testing a color element like a color tone and a luminance for a color image displayed on the screen, using a CCD camera and a microprocess. The system consists of a CCD camera, a line conveyor, a camera driving part, a remocon, a remote sensing part, a display and a PC including a color vision board and a CPU board. By applying the system to a process, reliability for a testing result can be improved and the absolute criterion to judge a part can be made.

현대생활에서 색채가 갖는 중요성은 점차 증가일로이고, 그런 현대를 컬러 에이지라는 말로 표현한다. 생활의 모든 영역이 패션 화 되어가고 있는 요즘은, 디자인 전문가뿐만 아니라 일반인들에게도 색채에 대한 교양과 지식이 요구되고 있다. 또한, 색채는 인간 감성에 미치는 즉각적인 소구력이 형태보다도 크므로, 마케팅의 중요한 판매요인이 되기도 한다. 그러므로 색채디자인 교육은 교양과정에서도, 전문적인 디자인 교육과정에서도 매우 중요한 커리큘럼이다. 색채는 색상.명도ㆍ채도의 삼속성으로 표현한다. 그러나 디자인현장에서의 색채는 명도와 채도의 복합개념인 톤을 사용한, 휴 앤드 톤 컬러 시스템을 주로 사용하고 있다. 그러므로 색채디자인의 교육에서도 색상은 물론, 명도와 채도를 합한 개념인 톤을 교육하는 것이 매우 중요하다고 생각된다. 그러나 국내에는 휴 앤드 톤으로 이루어진 컬러 시스템의 연구가 아직 미흡하다. 따라서 색채디자인의 교육현장에서도 외국의 컬러 시스템을 교육하고, 배색교육에 있어서도 수입된 색지를 주로 사용하고 있다. 색채의 증가하는 영향력을 생각할 때, 국내에서도 색채디자인 교육에 적합한 휴 앤드 톤의 컬러 시스템을 개발하고, 그에 의거 한 색채디자인용 색지를 개발하는 것은 매우 시급한 과제라고 생각된다. 본 연구에서는 이러한 색채디자인교육의 효율화를 위한 한 시도로서, 일반적인 색채디자인교육에 활용할 수 있는 $\ulcorner$휴 앤드 톤 253 색체계$\lrcorner$를 설계하였다.

The epidermal color is one of factors the space for ages. Instead of the epidermal color expression, it made with material and decoration under structure for make shade of meaning before have the new media. But now a days, the epidermal color of the fashion store is getting free owe to the development of color harmony, has a great notion that gets out of the subordinate from color, and it is a emphasized factor with expression and self-control. The epidermal color of the fashion store makes an effort to accept the development and changing of new media. It should show that there role and function is changing constantly according to a new technology, and it gave a motivation for reanalysis about existence and expression of the epidermal color. The purpose of this research is that look around the feature of the epidermal color system, elements, and principle. Then contemporary fashion store is expressive characteristics of epidermal color. Using epidermal color is not common, we can find lots of the case with surface color, layer color, interface color, though. The paper reflects on the meaning and concept of fashion store which enables the application of expressive characteristics on space through advanced technology. Meanwhile, the features of epidermal color such as immateriality of process and communication can be inferred from case analysis.

본 논문은 표준 디스플레이를 이용한 OLED의 색재현성 모델링을 제안한다. 비표준 RGB 디스플레이의 종류는 매우 다양하게 있으며, 그 색 재현 특성은 삼원색 좌표와 기준 백색 좌표 등 여러 가지 요인에 의해서 다르게 나타난다. 본 논문에서는 변환 매트릭스를 이용하여 OLED 디스플레이의 색 재현 특성을 표준 디스플레이에 재현할 수 있는 알고리듬을 제안한다. 본 연구에서 제안된 알고리듬을 이용하면, 색 재현 특성을 사전에 시뮬레이션으로 확인할 수 있으므로, 기존 디스플레이의 성능 향상이나, 새로운 디스플레이를 개발할 때 매우 유용하게 쓰일 것으로 기대된다.

From the perspective of reducing the sampling cost of color images at high resolution, block-based compressive sensing (CS) has attracted considerable attention as a promising alternative to conventional Nyquist/Shannon sampling. On the other hand, for storing/transmitting applications, CS requires a very efficient way of representing the measurement data in terms of data volume. This paper addresses this problem by developing a measurement-coding method with the proposed customized Huffman coding. In addition, by noting the difference in visual importance between the luma and chroma channels, this paper proposes measurement coding in YCbCr space rather than in conventional RGB color space for better rate allocation. Furthermore, as the proper use of the image property in pursuing smoothness improves the CS recovery, this paper proposes the integration of a low pass filter to the CS recovery of color images, which is the block-based ${\ell}_{20}$-norm minimization. The proposed coding scheme shows considerable gain compared to conventional measurement coding.

Yellow dye-stuffs in natural plant were extracted from a gardenia, saffron, safflower, amur tree and pagoda. And then they were used to color Korean handmade paper(Hanji) on using a mordant. The results of the degree of discoloration are as follows. 1. As for a gardenia(Gardenia jasminodes Ellis for. grandiflora Makino), the effects of coloring were outstanding in the acid area. But for the preservation, it might be desirable that used a lye in a dye-stuff obtained at $40{\pm}5^{\circ}C$. 2. As for saffron(Curcuma longa L.), when used alum as a mordant, it was colored to a medium yellow color with green color. But easily discolorated and was not desirable. And, it didn't fit in a dye-stuff of Hanji. 3. For safflower(Carthamus tinctorius L.), when pH was in the low acid it was colored to the cleaner yellow color. It was the distinction of discoloration that the degree of brightness's increase was low. 4. For amur cork-tree(Phellodendron amurense Rupr.), the effects of yellow coloring were great in the areas of acidity and alkali. But, when used alum, the degree of the discoloration was high and was not effective. 5. For pagoda tree(Styphnolobium Japonica L.), using a calcium hydroxide as a mordant, enabled the more than average yellow to be gained. The degree of discoloration was good.

This paper proposes an edge adaptive color interpolation for an ultra-small HD-grade complementary metal-oxide semiconductor (CMOS) video sensor in camera phones that can process 720-p/30-fps videos. Recently, proposed methods with great image quality perceptually reconstruct the green component and then estimate the red/blue component using the reconstructed green and neighbor red and blue pixels. However, these methods require the bulky memory line buffers in order to temporally store the reconstructed green components. The edge adaptive color interpolation method uses seven or nine patterns to calculate the six edge directions. At the same time, the threshold values are adaptively adjusted by the sum of the color values of the selected pixels. This method selects the suitable one among the patterns using two flowcharts proposed in this paper, and then interpolates the missing color values. For verification, we calculated the peak-signal-to-noise-ratio (PSNR) in the test images, which were processed by the proposed algorithm, and compared the calculated PSNR of the existing methods. The proposed color interpolation is also fabricated with the 0.18-${\mu}m$ CMOS flash memory process.
