In order to maintain and protect professionalism in color planning, the present study examined the process at the time of realization of color through color inspection and supervision in the actual construction site and suggested plans for improvement. Reflecting the characteristics that the governing body of the construction site is not a private person but an organization, the present study aims to provide institutional measures so that the supervisor of color construction at the actual site of construction can propose concerns related to proper construction at the right time, and the matters cannot be decided from the perspective of a layman. The institutional measures are proposed through the case of application of a process at the construction stage of the color planning at the construction site of Muju Taekwondo Park. First, the process clarified where the responsibility lies by specifying special conditions concerning color inspection on the field guide and color contract. Second, the sample for building materials was selected after obtaining it from a company capable of supply and is appropriate for the planned unit cost so that it could play an important role in realizing colors at the stage of basic design. Third, the process of construction was ensured not by temporary selection of colors but by continuous approval of colors in consideration of the conditions of construction site through letter of approval of color at each stage and point of time. Fourth, coordination of various color elements of other fields including landscape, interior, and electricity ensured construction of the whole structure in one color concept. Fifth, color inspection through the mock up of the site will minimize erroneous construction and reconstruction and prevent decrease in productivity. Sixth, this study also suggested more comfortable and positive color environment through evaluation by experts and users. The researcher of this study expects that color experts actively participate in the stage of construction to contribute to improvement of the color environment.

In recent studies on tone reproduction with the objective of reproducing natural looking colors in digital images, an integrated multi-scale retinex (IMSR) has produced great naturalness in the resulting images. Most methods, including IMSR, work in RGB or quasi-RGB color spaces. As such, this produces hue distortion from the perspective of the human visual system. Accordingly, this paper proposes the hue preserved multi-scale Retinex (HPMSR) method to obtain a high contrast and naturalness. The proposed method enhanced the $L^*$ and saturation values in CIELAB color space. As a result, the visibility in dark shadows in the resulting images was improved.

A robust and efficient text extraction is very important for an accuracy of Optical Character Recognition (OCR) systems. Natural scene images with degradations such as uneven illumination, perspective distortion, complex background and multi color text give many challenges to computer vision task, especially in text extraction. In this paper, we propose a method for extraction of the text in signboard images based on a combination of mean shift algorithm and weighting scheme of hue and saturation in HSI color space for clustering algorithm. The number of clusters is determined automatically by mean shift-based density estimation, in which local clusters are estimated by repeatedly searching for higher density points in feature vector space. Weighting scheme of hue and saturation is used for formulation a new distance measure in cylindrical coordinate for text extraction. The obtained experimental results through various natural scene images are presented to demonstrate the effectiveness of our approach.

For building an urban image, various elements such as symbolic building, ethnic characteristics, historical background, natural environment, and diverse cultural elements can influence on it. Many cities in developed countries are showing their unique urban image reflecting their own culture, history, and aesthetic tastes. Especially color, one of the major design elements, has greater impact than other visual factors to form an urban characteristic. Despite the long history and cultural background, Seoul as a capital city of Korea does not show an unique city image with the perspective of color. Recently, Seoul has been designated as '2010 World Design Capital' and implements various urban design projects. As a leading city of design, Seoul is trying to make its urban identity through the own symbolic environment color. The purpose of this study is to find an environmental color scheme for developing a desirable urban design through several cases of foreign countries. For the purpose, Paris, London, Amsterdam, and Tokyo were selected as case cities. Each of the cities showed their own cultural characteristics and made their unique urban image by appropriate usage of their natural environment, symbolic building, emblem of country, and so on. We need to consider these successful cases to build up the image of Seoul.

This study focuses on analyzing children's behavior from an integrated systemic perspective of the space and time and presenting a criterion and a guide of children-centered environmental color for intensifying their behavior affordance while considering functions of the space and color. Research was conducted as follows. Based on the spatial function and children's behavior, it figured out a prerequisite of educational environmental colors for behavior affordance. It extracted colors by dividing children's behavior affordance into 8elements considering a psychology of expectation and color function according to spatial and behavior affordance intensification elements. So 97school colors were selected for children's behavior affordance from abstracted colors by each element. Furthermore, it planned to suggest an environmental color guide for establishing elementary school's positive educational circumstances through enhancing behavior affordance, providing a potential to change a color environment at the educational space.

컴퓨터의 대중적 보급은 아날로그 컨텐츠들의 디지털화를 유도하고 있다. 컨텐츠의 디지털화는 종래의 아날로그 컨텐츠를 위한 미디어 시스템과는 차별화된 디지털 미디어 시스템의 출현을 초래하였다. 종래의 아날로그 미디어와는 달리 디지털 미디어 시스템은 다양한 사용목적과 사용범위를 한 시스템 내에 포괄하고 있다. 본 연구의 목적은 디지털 미디어 시스템 내부에 융합되어 있는 다양한 하위 시스템을 적절하게 표현할 수 있는 디자인 요소를 파악하고 그 효과를 실증적으로 검증하는데 있다. 이를 위해 본 연구에서는 사용자가 미디어에 대하여 갖는 관여도와 동기에 따라 효과적으로 디지털 컨텐츠를 사용할 수 있도록 도와주는 디자인 요소로서 색상차와 색조를 계시하였다. 그리고 색상차와 색조를 이용하여 디지털 미디어 시스템의 프로토타입을 구축하였다. 프로토타입을 이용한 통제된 실험결과 색상차와 색조는 사람들이 시스템에 대해서 느끼는 공간감에 중요한 영향을 미치며, 더 나아가 디지털 미디어 시스템의 사용성에도 유의미한 영향을 미치는 것을 알 수 있었다.

From a social psychological perspective, Make-up is an tool for run a lot smoother and perform communication efficiently. Many people give a turn to hair color through dyeing form due to yearning to change individual image through the image which the color is having. This paper study how make-up behavior, hair color and self-consciousness will affect the Level of Expected social-psychological effect of College Girl Students. In the sense of make-up behavior, according to result, a group of make-up behavior of self-satisfaction-oriented the level of expected social-psychological effect higher than a group of make-up behavior of tradition-oriented. Hair colors doesn't seem to be having much effect on the level of expected social- psychological effect, but have been shown to influence make-up behavior and self-consciousness. On the self-consciousness, a group of high self-consciousness the level of expected social-psychological effect higher than a group of low or fair self-consciousness. They doesn't have much effect passive expected effect as 'complement of self insufficiency' or 'a person consciousness' But they are affect active expected effect as 'the pleasure of change' and 'positive ascent'.

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.
