The purpose of this study is to extract the rage on exterior colors of Elementary schools in harmony with natural colors as the colors of sky and trees, of Which the colors is basically composing the natural environment. The theory of harmony in NCS relatively expressing the changed colors according to the color stimulation condition is the contrast of same color fit for the nature. NCS has a systematic open mind considering parts in the whole. The study suggests appropriate strategy for Eco-color scheme. The result shows that it's desirable to select YR Group in the elementray school of exterior color design, The Eco color planned by NCS is expected to clarify the interrelationship between children and environment. This practical use should be continuingly tried in the color design of interior for elementary schools.

The purpose of this study was to investigate the effects of design modification, decoration and color scheme of traditional Korean women's clothing on impression formation by 2 age groups of women. The instruments developed for the study were 2 sets of stimuli and a response scale. Stimuli I (design stimuli) consisted of 6 line drawings of female figures in Korean clothing and modified Korean style clothing, whereas stimuli II (color stimuli) consisted of 6 colored drawings of female figures in different color schemes. The 7-point semantic differential scale of 14 bipolar adjectives were used for the response scales. 144 female college students and 144 middle·aged women subjects were randomly assigned to one of 6 drawings from each set of stimuli. The data were analyzed by factor analysis, ANOVA and t-test. 1) There factors emerged to account for dimensions of design and color scheme, respectively. The first factor was interpreted as Evaluation/prestige both in design (stimuli I) and color scheme (stimuli II), the second factor was Modernity for stimuli I, and the third factor for stimuli I was Practicality. On the other hand, the Luxuriousness/Individuality was factor 2 and Modernity was factor 3 for stimuli ll. 2) Modification had the largest effect on impressions regarding design and decorated designs had a partial effect on the impression of Modernity and Practicality. The female figures in modified Korean style clothing were perceived as more prestigious, modern and practical than those in traditional Korean clothing. 3) Color schemes had little effect on impressions, while perceiver's age had a larger effect. Middle·aged women formed more positive impressions toward Korean clothing of various color schemes than female college students.

In this paper, we propose a new hand gesture recognition scheme using hand poses captured from a web camera. The key idea of this scheme is to extract skin color from the background-subtracted image. To extract skin color, in the first phase, we subtract background by repeatedly comparing the stored initial frame with next frames. And then we eliminate noise using dynamic table. In the second phase, we exactly recognize hand gesture by extracting skin color from ${YC_b}{C_r}$ color region.

As the development of digital and technological sophistication, architectural speculation hierarchy had been more and further diversified and brought on the changes with system of architectural color meaning. Architectural color had been influences on evocation of effect and meaning by association, had the attributes of communication with human being, in common with precision, non-verbal and non-quantitative creative field. Color could not been defined as one conclusively standard symbol and figured out in inter-relationship with correlation, mental status and interaction. Color in architecture could been promptly defined as the tool of visualization in building or structure through the essential criterion to be measured with shape, space and author's thought. In consequence, color in architecture could been re-defined as the speculation concept for real characteristics creation(color as design factors on architect and color to be expressed by program) in itself, and color supporting system as for transposition of light and space enlargement scheme. Consequently, color in architecture could been turnover from perceived color to anthropological color through the real value creation scheme in itself.

The purpose of this study is to propose a new direction for color schemes of city signages to provide psychological stability to business owners and improve business value. Types of city sign color schemes and Feng Shui awareness of business owners were examined. Color schemes for signs were proposed, reflecting city landscape colors, color perception theory, and the Feng Shui Sangsaeng Sanggeuk theory. Results of the study can be summarized as follows. First, in order to secure colorscape quality of existing city buildings, signs should be small and consist of only three or fewer colors. Second, existing signage colors and the Feng Shui ideas of business owners have something in common with the five traditional cardinal colors. Thus, it can be interpreted that Feng Shui ideas are deeply rooted in the color use awareness of the Korean people. Third, background colors of signages can reflect the idea of innate Sangsaeng according to the Bonmyeonggung of business owners. The concept of acquired Sanggeuk can also be applied to other design elements such as characters. Fourth, as a second choice according to the function of sign, city landscape or preference of business owner, etc., the background color can remain a color of Sangsaeng, while other design elements such as characters can use a color scheme corresponding to Bihwasaek. Fifth, signs can create a statement and stand out using lightness contrast or saturation contrast theories. A variety of sign color schemes are also possible just by altering the lightness and saturation levels.

In this paper, instead of conventional color management method that using spectrum analysis, a simplified color management scheme is proposed that is low-cost required method to reproduce the visual color perception of human. Proposed scheme uses computer color scanner to obtain a bit map image from dyed original color sample, and conducts pixel analysis by image histogram. From obtained image histogram, extract the color and RGB value from histogram that shows dominant pixel distribution of the sample image.

For the compression of color images, a common bitmap usually is generated to replace the three individual bitmaps that originate from block truncation coding (BTC) of the R, G and B channels. However, common bitmaps generated by some traditional schemes are not the best possible because they do not consider the minimized distortion of the entire color image. In this paper, we propose a near-optimized common bitmap scheme for BTC using Binary Ant Colony Optimization (BACO), producing a BACO-BTC scheme. First, the color image is compressed by the BTC algorithm to get three individual bitmaps, and three pairs of quantization values for the R, G, and B channels. Second, a near-optimized common bitmap is generated with minimized distortion of the entire color image based on the idea of BACO. Finally, the color image is reconstructed easily by the corresponding quantization values according to the common bitmap. The experimental results confirmed that reconstructed image of the proposed scheme has better visual quality and less computational complexity than the referenced schemes.

A hybrid color and grayscale images encryption scheme based on the quaternion Hartley transform (QHT), the two-dimensional (2D) logistic map, the double random phase encoding (DRPE) in gyrator transform (GT) domain and the three-step phase-shifting interferometry (PSI) is presented. First, we propose a new color image processing tool termed as the quaternion Hartley transform, and we develop an efficient method to calculate the QHT of a quaternion matrix. In the presented encryption scheme, the original color and grayscale images are represented by quaternion algebra and processed holistically in a vector manner using QHT. To enhance the security level, a 2D logistic map-based scrambling technique is designed to permute the complex amplitude, which is formed by the components of the QHT-transformed original images. Subsequently, the scrambled data is encoded by the GT-based DRPE system. For the convenience of storage and transmission, the resulting encrypted signal is recorded as the real-valued interferograms using three-step PSI. The parameters of the scrambling method, the GT orders and the two random phase masks form the keys for decryption of the secret images. Simulation results demonstrate that the proposed scheme has high security level and certain robustness against data loss, noise disturbance and some attacks such as chosen plaintext attack.
