Korean film "Swiri"(1999) as well as a popular film is the first Korean blockbuster Film. In addition, the number of viewers is very common in Korea a large ripple effect that Korea film "Swiri" in his works were selected to act as a hero and contextual significance confrontation between the two figures through the symbolic analysis of clothing styles and colors Analyzing the meaning of space and a scene in the background with the colorful costumes and would like to study. In detail, the film's central character theme and image suggesting that dramatic reversal the character's personality through the clothes I was expressed through clothing styles and colors were analyzed with symbolism. Korean film "Swiri" the film's DVD player application from the situation or story that is considered to be important psychological conflicts selected twenty-seven screens in the study were collected still images. Data collected for the effect of color contrast and color analysis technical. The center of the video footage, the film's main characters costumes and background colors of the space was to examine the significance and symbolism.

In this paper, we propose the robust object detection algorithm with spatial gradient information. To do this, first, we eliminate error values that appear due to complex environment and various illumination change by using prior methods based on hue and intensity from the input video and background. Visible shadows are eliminated from the foreground by using an RGB color model and a qualified RGB color model. And unnecessary values are eliminated by using the HSI color model. The background is removed completely from the foreground leaving a silhouette to be restored using spatial gradient and HSI color model. Finally, we validate the applicability of the proposed method using various indoor and outdoor conditions in a complex environments.

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.

Automatic human face detection in a complex background is one of the difficult problems In this paper. we propose an effective automatic face detection system that can locate the face region in natural scene images when the system is used as a pre-processor of a face recog- nition system. We use two natural and powerful visual cues, the color and the human head shape. The outline of the human head can be generally described as being roughly elliptic in nature. In the first step of the proposed system, we have tried the approach of fitting the best Possible ellipse to the outline of the head In the next step, the method based on the human skin color space by selecting flesh tone regions in color images and histogramming their r(＝R/(R＋G＋B)) and g(＝G/R＋G＋B)) values. According to our experiment. the proposed system shows robust location results

This study intended to improve traffic safety in work zones using fluorescent orange color traffic signs. For this end, the current problems of existing traffic signs and facilities in work zones were analyzed and some good examples of foreign countries were compared. More specifically, in order to identify current problems, the basic shape and color of traffic signs in use were examined through literature review, surveys and field studies. It was found that the fluorescent color worked more effectively than other colors in terms of visibility and conspicuity in work zone sign system. For evaluation, both Conspicuity surveys and in-door simulator experiments were conducted to effectively assess the merits and demerits of different types of traffic signs for work zones. The results of evaluations showed that black lettering on a fluorescent orange background outperformed more than 70% in terms of visibility and ability to call drivers' attention compared with those from black/red lettering on yellow/white backgrounds currently used at work zones on expressways and national highways. In addition, simulated driving experiment disclosed that drivers recognized the fluorescent orange background sign 15m ahead compared with the yellow background sign and 25m ahead compared with the white background sign, respectively. As for the diamond-shaped "Under Construction" sign, drivers recognized fluorescent orange background 11m ahead compared with the yellow background sign and 19m ahead compared with the white background sign, respectively.

The purpose of this study was to identify the effect of four clothing cues dot pattern size and ground field of color area ratio on dress's wearer image. The experimental materials developed for this study are a set of stimuli and response scales(The 7-point semantic). The stimuli were 30 color pictures manipulated with the combination of dot pattern size, dot pattern on background of color area ratio and neutral dress's using computer simulation. The subjects were 180 female undergraduates living students in Gyeong-nam. The result of this study are as follows: Image factor of the stimulus was composed of 5 different components (visibility, gracefulness, attractiveness, cuteness, womanly). Especially, Neutral color combination independently influenced the every components. In regarding the effect of interaction between each variable, the combination of dot pattern on background of color area ratio, dot pattern size on the combination had cuteness, womanly.

In this paper, we propose an algorithm both geometric correction using a grid point image and radiometric adaptive projection that dependent upon the luminance of the input image and that of the background. This method projects and captures the grid point image then calculates the geometrically corrected position by difference between the two images. Next, to compensate color, a corrected image is calculated by the ratio divided luminance of an input image by luminance of arbitrary surface. In addition, we found the scaling factor which controls the contrast to avoid clipping error. At this time, the scaling factor is dependent on mean image lightness when background is determined. Experimental results show that the proposed method achieves good performance and is able to reduce the perceived color clipping and artifacts, better approximating the projection on a white screen.

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.

It has been suggested that primates' trichromatic color vision is an adaption for folivory and frugivory. Ripened fruit frequently is red against a green background. Given this, the question for our research was whether the ecological relationship between red and green plays any role in figure-ground organization that is an essential step in forming our perception of objects? In this study, it was tested which color looked most strong as a figure, using a red circle on a green background and a green circle on red background. The results of Experiment 1 showed that most participants saw the red circle for the figure more than the green circle. However, this effect was significant only in females, but not in males. Accordingly, this result suggests that the visual development of figure-ground organization based on red-green color combination may differ between males and females. In Experiment 2, it was surveyed that the results of Experiment 1 was simply not by the sex difference of color preference. The gender difference of the figure-ground organization on red-green stimuli are discussed in terms of some recent hypotheses such as gatherer-hunter hypothesis.
