  • In this paper, detection algorithm of face region based on skin color of in the TV images is proposed. In the first, reference image is set to the sampled skin color, and then the extracted of face region is candidated using the Euclidean distance between the pixels of TV image. The eye image is detected by using the mean value and standard deviation of the component forming color difference between Y and C through the conversion of RGB color into CMY color model. Detecting the lips image is calculated by utilizing Q component through the conversion of RGB color model into YIQ color space. The detection of the face region is extracted using basis of knowledge by doing logical calculation of the eye image and lips image. To testify the proposed method, some experiments are performed using front color image down loaded from TV color image. Experimental results showed that face region can be detected in both case of the irrespective location & size of the human face.

  • Color image is largely corrupted by various ambient illumination. However, human perceives always white color as white under any illumination because of a characteristic of human vision, called color constancy. In the conventional algorithm which applied the constancy effect, after the RGB color space is transformed to the IHS(Intensity, Hue, and Saturation) color space, then the hue is preserved and the intensity or the saturation is properly enhanced. Then the enhanced IHS color is reversely transformed to the RGB color space. In this process, the color distortion is included due to the color gamut error. But in the proposed algorithm, there is not transformation. In that, the RGB color is considered as 3 dimensional color vector and we assume that white color is the natural daylight. As the color vector of the illumination can be calculated as the average vector of R, G, and B image, we can achieve the constancy effect by simply rotating the illumination vector to the white color vector. The simulation results show the efficiency of the vector rotating process for color image enhancement.

  • The purpose of this study was to examine the effects of VM components(facade color and show window type) on store image and purchasing intention of fashion stores. The subjects were 428 male and female university students in Daejeon and Chungnam province. The measuring instruments were 6 stimuli manipulated by $3{\times}2$ factorial design of facade color and show window type, and a self-administrated questionnaire consisted of store image, purchasing intention, and subjects' demographic characteristics. The results were as follows. First, facade color mainly affected store image and purchasing intention. White color was preferred as more positive images(pleasurable, comfortable, neat, and modern), and showed higher purchasing intention than brown color. Second, show window type affected some store images. Semi-open type was perceived as more pleasurable image than enclosed type, whereas enclosed type was perceived as more luxurious, neat, and attractive image than semi-open type. However, show window type didn't affect purchasing intention. Third, subject' sex affected store image and purchasing intention. Male subjects perceived more positively on store image and had higher purchasing intention than females. This study suggested that facade color and show window type are important VM components affecting store image and purchasing intention.

  • The objectives of this study were to examine how image evaluation and preference of women's clothing color vary according to perceiver's culture, gender, and clothing color; to investigate the differences of image evaluation according to body type and the clothing color; and to disclose what image affects to the clothing color preference of Korean and American. Subjects were 388 Korean and 363 American college men and women. The American evaluated the wearer more elegant, feminine, and neater than the Korean did. Clothing color gave significant influence on perception of all image variables. Koreans showed that red and blue color shirts were perceived to be individualistic. Koreans considered blue, indigo, purple, gray, and black were perceived to be less feminine. This means that they evaluated the colors of blue range and low chroma were masculine according to their traditional attitude. Women were more attracted by indigo and purple, while men tended to evaluate yellow as an appealing color. The evaluation of sociability varied depending on the perceiver's culture and clothing colors. The corpulent body type had negative evaluation rather than the ordinary one without the relation with the color of clothing for Koreans and Americans. The evaluation of sociability of Americans had an interaction effect by the body type and clothing color. Attractiveness gave the first significant influences on clothing color preference, and the next came individual(-) and splendid image for Korean men. The individual image gave Korean men to be negative effect. Attractiveness, elegance, and sociable image gave significant influences on clothing color preference in Korean women. For American men, elegance gave the first significant influences on clothing color preference, and the next came sociability and neatness, while elegance was the first and the next came sociability and attractiveness for American women.

  • This paper presents a new image cache algorithm for real-time implementation of high-resolution color image warping. The cache memory is divided into four cache memory modules for simultaneous readout of four input image pixels in consideration of the color filter array (CFA) pattern of an image sensor and CFA image warping. In addition, a pipeline structure from the cache memory to an interpolator is shown to guarantee the generation of an output image pixel at each system clock cycle. The proposed image cache algorithm is applied to an FPGA-based real-time color image warping, and experimental results are presented to show the validity of the proposed method.

  • This study develops textile pattern design ideas created through the visualization of music. Methods of auditory and synesthesia were employed to analyze various attributes of popular music genres and appoint language image, shape image, and color image to obtain their interrelationships. This study provides data that can be used to express emotional images on textile print pattern designs. This research used different genres of popular music as stimuli. The language image was extracted and introduced to the overall color scheme; in addition, the color image was verified. The analysis of the color image was executed by applying it with the color set image scale of I.R.I colors. Then, the color image of the target genre of popular music was examined and analyzed through a color tone system. The preference in shape image was realized through visual images based on basic principles of points, lines, and sides composition; subsequently, an analysis of the emotional image of popular music followed. An examination of the emotional images of different popular music genres have led to the discovery that language image, color image, and shape image all share a common emotional image. There was also a realization that similarity and interrelationship exists in language, color, and shape images experienced by listening to popular music.

  • Color plan that contains corporate color of Seoul apartment has a great influence on city environment, considering high-rise vertical dispersion and extent. Therefore, it is necessary to view color plan from an integrative viewpoint. Here, this research aimed at deriving guideline factors of esthetic color plan based on city identity, by recognizing the importance of apartment color and color plan characteristic of recently built brand apartments. Exterior color plan characteristic of Seoul brand apartments seen in this research, first, most of dominance colors were in same color similar tone with warm color in bright and warm image, as the psychological function, accessory colors appeared in similar tone of similar color harmonious with the dominance color. Also, accent color was highlighted with its identity through cooperative color. Second, emotional effect diminished size and weight of high-rise apartment. The upper levels showed clear and clean image, middle to lower level showed stability and comfortable image, on the whole, refined and urbane image that aim for natural and modern image. Therefore, apartment color plan requires, first, in respect of dominance color, unity is required proper for urban image by preparing color permission limitation standard. Second, dominance color and accessory color require historicity and differentiation in sociality that urban identity gets. Third, high-rise upper level cooperative color accent color requires compatibility with urban landscape. Lastly, guideline along with rate is required for color, tone, and pattern, etc. by extent contrast. Here, apartment color plan requires consistent research as urban environment color, also, base study should be accelerated as a part of competitive city branding.

  • The purpose of this study is to find out the color preference on rural rooftop color. Today, public profit value of a rural community has been heavily recognized in the areas of preservation of pro-environmental and traditional life styles and foundation of collective community. Comparatively with urban, rural town conserves the scenic of those days when the historic landscape existed. Therefore, elements of historic and tradition in rural town are interesting resources to people who want traditional experience. Color is one of the most influenced elements for the image of Landscape. On the other hand, radical modernization has brought conflicting color element that does not blend with existing environmental color. Among others, roof represents one of the important traits of rapidly developing rural community due to vast amount of space it covers. In order to come up with more appropriate coloring scheme, it is necessary determine color that forms a balance with present conditions of rural life and historic landscape. This study provides more objective rooftop coloring selection process by employing additional surveys regarding color image adjective. I justified necessity of the balance between environmental color and roof color through analyzing correlation between environmental color of the rural town and Color Image Scale of the preliminary selection of roofs.
