A total of ninety swine ($79.0{\pm}2.2\;kg$) were employed for 58 d to determine the meat quality of pigs fed fermented agricultural by-products (FAB) mainly consisting of brewers grain shell. FAB was replaced with commercial feed at dietary levels of 20%, 40%, 60%, 80%, and 100% (T1) and 30%, 60%, 100%, 100%, and 100% (T2) at 1, 2, 3, 4 and 5-9 wk, respectively. Compared with the control (CON) feed, FAD feed had lower moisture and nitrogen-free extract content, and higher crude fat, crude fiber, and total calorie (p<0.05). The protein content, amino acid profile, and pH values of pork loin were not affected by dietary treatment. However, higher moisture, crude ash, and meat cholesterol, and lower fat, were found in CON compared with treatment (p<0.05). FAB treatment significantly improved drip loss and cooking loss value (p<0.05), and increased the CIE $L^*$ values of loin and back-fat surface, whereas it decreased the CIE $a^*$ values of loin surface (pp<0.05). The results indicate that dietary FAB affected meat cholesterol and fat content, and improved drip loss and cooking loss, but had no affect on amino acid composition.

In this study, we have compared the relative importance of various washing condition affecting on soil release for P/C blended fabrics. P/C blended fabrics were soiled by the pad-dry method with aqueous and oily soil. The washing procedures of soiled samples were performed by Atlas Launder-Ometer with 27 wash conditions which are combinations of wash temp. wash time and detergent cone. The degree of soil-release was evaluated with CIE 1976 Lab color difference before and after washing. Multiple regression analysis was used to evaluate the optimum wash conditions and the relative importance of the factors providing maximum soilremoval.

In this paper, we propose a novel saliency detection framework based on illumination invariant features to improve the accuracy of the saliency detection under the different light conditions. The proposed algorithm is divided into three steps. First, we extract the illuminant invariant features to reduce the effect of the illumination based on the local sensitive histograms. Second, a preliminary saliency map is obtained in the CIE Lab color space. Last, we use the region growing method to fuse the illuminant invariant features and the preliminary saliency map into a new framework. In addition, we integrate the information of spatial distinctness since the saliency objects are usually compact. The experiments on the benchmark dataset show that the proposed saliency detection framework outperforms the state-of-the-art algorithms in terms of different illuminants in the images.

When wood is exposed to natural weathering and UV radiation discoloration progresses. The color variation of heat-treated wood was investigated. Four domestic species were selected and heat-treated at $220^{\circ}C$ and naturally weathered for 42 days. Their colors were measured with a portable colorimeter. The color variations were different between species. The Korean red pine specimens were highly discolored by the natural weathering even though they were heat-treated. In contrast to Korean red pine, Korean pine is less discolored. The maximum color difference of larch was lower than Korean red pine. All specimens of birch exceeded the color difference criterion of 15 after 25 hours with the maximum of 28.

A complete analysis of the color-viewing-angle properties of different displays is presented herein using color-viewing-angle measurements made with a Fourier-optics system. The color gamut in the CIE u'v' chromatic plane was computed for all the viewing angles. The introduction of the lightness using the $L^*a^*b^*$ color space allowed a more precise analysis of the emissive properties of each display. The displays can be directly compared using a common reference. The viewing-angle dependence can be analyzed in full detail using the on-axis values as reference. The gravity center behavior and area of the color hull were computed for a more precise evaluation and comparison.

This study was investigated to establish the optimum conditions of dyeing silk fabric with Brassica campestris. This experiment was done under different dyeing conditions of dye concentration, dyeing temperature, dyeing time, dyeing repeating times, and mordants which were treated pre, syn, and post methods. The effects of dyeing conditions and mordanting were evaluated in terms of dyeaffinity(K/S value) and CIE-Lab color factors. Also, the effect of mordanting on color fastnesses was assessed. The dyeaffinity increased remarkably as dye concentration increased up to 200% owf. The dyeaffinity increased continuously with dyed temperature and reached dyeing equilibrium at $80^{\circ}C$. The maximum dyeaffinity was observed at 30minutes of dyeing time. In the relationship between the K/S value and dyeing repeating times, the K/S value became higher as repeating time was increased. The changes of surface color and colorfatness of dyes were not increased greatly on all mordanting states. The extracts of Brassica campestris produced mainly yellow color in silk fabric. The antimicrobial activity existed slightly as the ratio of 22.7%.

This paper details the synthesis of α-FeOOH (goethite) rods through the reaction of iron (III) nitrate with KOH as a strong base, and shape control of the particles for use as a yellow inorganic pigment. The crystal phase of the α-FeOOH crystal with OH content according to the addition of KOH and the change in morphology were investigated. The optical properties varied with the aspect ratios, and the yellowness increased with increasing aspect ratio. However, the enhanced chromaticity characteristics reversed beyond a certain critical aspect ratio. Thus, the relative optimal aspect ratio of the α-FeOOH rods as a vivid yellow inorganic pigment was derived. The morphology and coloration of the prepared rods were investigated in detail using X-ray diffraction (XRD), scanning electron microscopy (SEM), UV-vis spectroscopy, and CIE Lab color parameter measurements.

To set up the outstanding and scientific dyeing method in making the condensed liquid of pigment obtained from onion skins and the improved reliability, the following basic experiments were performed. The pigment was extracted in the distilled water at $70^{\circ}C$ and methanol at room temperature and then it was analyzed with LC/MS/MS system (Liquid Chomatography/Mass Spectroscopy/Mass Spectroscophy, LIQ Advantage Max, Thermo Finnigan, USA) for its pigmental characteristics. The unrefined silk and refined silk were dyed by making use of the derived pigment in such a way. The chromameter (CR-200, Minolta, Japan) was used to measure the change in surface color in textiles to be dyed by the extracting condition and the color difference ${\Delta}E$ was determined according to the color difference formula CIE LAB through measuring the psychometric lightness L* and chromaticity coordinates a* and b*.

SSIM은 인간의 시각 체계가 이미지의 구조적 정보에 예민하다는 점을 이용하여 여러 가지 구조적 정보들의 유사성을 계산함으로써 이미지를 평가하는 대표적인 이미지 평가 기법이다. 하지만 SSIM은 컬러 이미지들에 대해 색 차이를 고려하지 못하는 문제가 있다. 이러한 문제를 해결하기 위해, HSI 색 공간을 활용한 SHSIM 기법이 제안되었으나 이 기법 또한 두 컬러 이미지 간 인지적인 색 차이를 충분히 반영하지는 못하고 있다. 본 논문에서는 CIE Lab 색 공간을 도입하여 대응 되는 픽셀들의 인지적 색 차이를 계산하여 이미지 평가에 활용하는 방법을 제안한다. 제안하는 기법의 성능을 평가하기 위해, 이미지 평가 분야에서 가장 많이 알려진 네 가지의 데이터베이스와 네 종류의 평가 기준들을 이용하였다. 실험 결과에서는 제안하는 기법이 다른 기법들보다 인간 시각 체계와 더 상관성이 높다는 것을 보여줌으로써 성능을 증명하였다.

The purpose of this study was the development of a digital water color measurement system using a CCD optical device. Photographs of the standard medium of Forel and Ule water color scales in the laboratory, and one of sea surface above a Secchi disc (Z=SD/2) immersed in seawater were taken. The colors of these pictures were estimated with the value of CIE $L^*a^*b^*$. Water color assessment was conducted with a digital photo-image. In the case of the Forel scale (No. 1-11), the $b^*$ value was so high that the water color number was large. In the Ule scale (No.11-21), the $a^*$ value became high, which is why the number on the water color scale was large. The color of these pictures showed that the $a^*$ value in the Forel scale and the $b^*$ value in the Ule scale increase with the increase of the F value. The $a^*$ value of seawater color was always lower than the one on the Forel and Ule water color scales. This indicates that the color of the scales differs from actual seawater color. It was concluded that water color number can more effectively be assessed by estimating the ${\Delta}Eab^*$ color difference between the water scales and actual seawater color.
