The present study aims to assess test uncertainty assessment method of nominal wake field measurement by a Stereoscopic Particle Image Velocimetry (SPIV) system in a towing tank. The systematic uncertainty of the SPIV system was estimated from repeated uniform flow measurements. In the uniform flow measurement case, time interval between image frames and uniform flow speed were varied to examine the effects of particle displacement and flow around the SPIV system on the systematic standard uncertainty. The random standard uncertainty was assessed by repeating nominal wake field measurements and the estimated random standard uncertainty was compared with that of laser Doppler velocimetry. The test uncertainty assessment method was applied to nominal wake measurement tests of a very large crude oil carrier model ship. The nominal wake measurement results were compared with existing experimental database by other measurement methods, with its assessed uncertainty.

Since the LBP algorithm has the characteristic of local texture expression, it is possible to obtain completely different results depending on the extraction location and the size of the reference image and the sample image. In order to solve these shortcomings, in this paper, we first investigate the basic characteristics of LBP, make the size of the reference image (100×100) in order to include most of the characteristics in the image, and select a sample image (40×40) extracted from an arbitrary point. After finding the matching position in the LBP of the reference image by using the correlation test between the LBP of the reference image and the LBP of the sample image, a chi analysis method is used to find the reference image that most closely matches the sample image.

The objective of this study is to examine the images of the current uniforms and to provide the basic references in designing female flight attendants uniforms. In Incheon International Airlines, 11 of the major airlines with the most passengers along with the highest capacity were chosen and 22 pieces of photographs were collected, two photos coming from each airline companies. The semantic differential scale has been formed by 16 pairs of adjectives. Then, it has conducted a statistical analysis using a SPSS WINDOWS that contains 475 copies of the selected questionnaires (375 of the non-flight attendants, and 100 of the female flight attendants). The following are the results and the conclusion of this study. According to this study, four main components of the uniforms of the female flight attendants were attractiveness, femininity, noticeability, and activity, which have occupied $65.9\%$ of the total variance. It was concluded that attractiveness and femininity were two main factors in perceiving the females' uniforms. According to the results of the uniform image difference, it was shown that Asiana Airline's uniform is the most attractive and Cathay Pacific Airline uniform is the most feminine. The most noticeable uniform was from Singapore airline which included cultural and traditional components of its own national colors. Pants suits of Lufthansa airline and Northwest airline were shown as the most active uniforms. There were significant differences in uniform images according to subjects' gender, age, education, and occupation. Men perceived uniforms more attractive, feminine, and active than women. People over 40 perceived uniforms more attractive, feminine, and active, and the High School graduates perceived uniforms more feminine and active. On occupational basis, Federal workers and Educators perceived uniforms more active on uniforms. Passengers who take planes once a month perceived uniforms more attractive, feminine, and active.

This paper proposes an image enhancement-based license plate detection algorithm to improve the overall performance of system. Non-uniform illumination conditions have huge impact on overall plate detection system accuracy. In this paper, we propose an algorithm for color image enhancement-based license plate detection for improving accuracy of images degraded by excessively strong and low sunlight. Firstly, the image is enhanced by Multi-Scale Retinex algorithm. Secondly, a plate detection method is employed to take advantage of geometric properties of connected components, which can significantly reduce the undesired plate regions. Finally, intersection over union method is applied for detecting the accurate location of number plate. Experimental results show that the proposed method significantly improves the accuracy of plate detection system.

The purpose of this research was to conduct a comparison analysis of color in the characteristics and image of Korea/China/Japan airline uniforms. Research subjects for this research included 19 Korean, Chinese and Japanese airlines servicing the Incheon International Airport in South Korea. The analysis methods are based on the Munsell Color Order System and PCCS (Practical Color Coordinate System) tone classification in order to examine the color characteristics. For the color image analysis, the present research performed a positioning on Shigenobu Kobayashi's color images scale with adjectives in order to compare the resulting differences. As a result of the analysis, this research discovered the following; First, achromatic colors were found to be used most frequently in flight attendant uniforms of Korea/China/Japan. In Korean flight attendant uniforms, YR/Y, GY and B/PB/P; in Chinese, R/PB, RP, YR/Y/GY and BG/P; in Japanese, RP, R/P/PB and Y/BG were found in order. As for the main uniform colors, Korean flight attendant uniforms were found to be in the colors YR, and R/GY/B/P; Chinese flight attendant uniforms, R, PB, and P/B; and Japanese flight attendant uniforms, R, BG, B, RP and N. Second, Korean flight attendant uniforms used W and It most frequently; China flight attendant uniforms, W; and Japanese flight attendant uniforms, W and v. Regarding the main colors, Korean flight atteddant uniforms used lt/g and v/p; Chinese flight attendant uniforms, v, dp and s/d/dkg; and Japanese flight attendant uniforms, v/dkg and Bk. Third, after positioning each country's uniform color combination bars on the Kobayashi image scale, Korean flight attendant uniforms showed classic images along with casual/pretty/elegant/chic images; Chinese flight attendant uniforms displayed, casual images as well as, dynamic/gorgeous/chic/cool casual/dandy images; and finally, Japanese flight attendant uniforms converyed dandy images along with casual/gorgeous images. This research findings indicate that Korea/China/Japan airlines' flight attendant uniforms seek for differentiated image establishment by reflecting their own CIs and unique national cultures in the uniform color marketing.

Today the Olympics are considered representative of a culture that symbolizes the country's image and cultural specificity, and important colors act as effective means of Olympics marketing. Each color is unique to the natural environment and cultural heritage is one of the languages of each country, region or community and it symbolizes. Hence, the purpose of this study was to examine the color and to view the color image displayed on Olympic uniforms based on the national color sensibility. After analyzing the color image of the Olympic athletes, including six kinds of uniforms and operational personnel, a cool casual/casual image is created more frequently, followed by a modern, gorgeous, dynamic, elegant/chic, dandy/classic image. The uniform color is consistent with the national image and the theme of the Pyeongchang Olympics is to enhance the country's competitiveness by widely promoting the national image of Korea around the world. Furthermore, it is necessary to provide the empirical basis for creating the 2018 Pyeongchang Winter Olympic uniforms.

In order to accurately perform multispectral imaging using a multiplexed illumination, intensity of illumination in a scene must be uniform. For image acquisition that requires accurate color information, even if not multispectral imaging, the illumination information must be accurate, and a flat light source or illumination calibration is performed for accurate illumination characteristics. In this paper, we propose a method of color correction to uniformly illuminate an image with non-uniform illumination intensity. The proposed method uses multispectral imaging instead of illumination calibration for color correction. First of all, we perform multispectral imaging with two images obtained from non-uniformity illumination to acquire spectral reflectance. The obtained reflection spectrum is relit as the illumination characteristic of the image obtained from general planar light such as fluorescent light or sunlight. By comparing the image obtained by relighting with the uniformly illuminated image, the non-uniformity of the illumination is confirmed, and the color correction is performed as the image obtained from the uniform image. It is expected that the experimental results will confirm whether the non-uniformity of the illumination is uniformly corrected and reduce the restriction of illumination in obtaining the color information of the image.

Performances of some image restoration filters are compared and evaluated on SNR gain and subjective test. Test images used here are the GIRL and PLANT images corrupted by Gaussian, uniform, BSC, and impulse noise, respectively. Experimental results show that the scalar DCT-Wiener filter among them is comparatively superior to others in Gaussian and uniform noise. On the other hand, the median filter is much better than others in BSC and impulse noise.

The work-man's Uniform should be coincident with the image of his firm and accounted of the function according s its purpose. We made questions to 404 workers at 8firm in our country through the questionnaire papers to know about a work-man's uniform and researched whether the satisfactory in wearing his uniform had relation with his type of business, grade, carrier, age, marriage, and monthly income. The results of this study is as follows; 1. In the case of wearing the uniform many workers answered they always wore their uniform in the firm. It was shown that the office workers wore their uniform much more than workers in the production department. The longer the time working, the older age, the lower grade of school career are, he more workers wear. the order of the importance for he uniform was the function, the symbol, the originality, and the fashion. The longer their career in the firm was, the more important the function of their uniform was. 2. The order of dirty pat in taking care of the uniform was cuffs, color, the front of part in an upper garment and below the knee, the hip in pants It was very easy for the workers in the experts, or administrators and office workers than others to be dirty in the cuffs part of the uniform. Worn part of the uniform showed highest cuffs in an upper garment and a zipper in pants. The order of cleaning the uniform was washing by water, no ironing, and cleaning in their house.
