  • Though flash images are in general less noisy and present details better than no-flash images, they may sometimes be unnaturally saturated to white/gray-tone and have ridiculously strong shadows around the foreground objects due to the strong flashlight. In this paper, we propose a new algorithm to improve the color quality of the flash images by transfer of the color information of the same-scene no-flash images. The proposed algorithm preserves the vivid edges and the clean details of the flash image while transferring natural colors of the no-flash image, so that it makes the constructed images of the better subjective quality. The performance of the proposed algorithm is verified by experiment which applied to the two types of images with different noise levels.

  • It has been suggested that the endoscopic color of intramucosal gastric carcinoma is correlated with mucosal vascularity within the carcinomatous tissue. The development of electronic endoscopy has made it possible to quantitatively measure the mucosal hemoglobin volume, using a hemoglobin index. The aim of this study was to make a software program to calculate the hemoglobin index (IHb) and then investigate whether the mucosal IHb determined from the electronic endoscopic data is a useful marker for evaluating the color of intramucosal gastric carcinoma, in particular with regard to its value for discriminating between the histologic types. The mean values of IHb for the carcinoma (IHb-C) and the mean values of IHb for the surrounding non-cancerous mucosa (IHb-N) were calculated in 75 intestinal-type and 34 diffuse-type gastric carcinomas. Then, we analyzed the ratio of the IHb-C to IHb-N. The mean IHb-C/IHb-N ratio in the intestinal-type carcinoma group was higher than that in the diffuse-type carcinoma group (1.28$\pm$0.19 vs. 0.81$\pm$0.18, respectively, p<0.001). When the cut-off point of the C/N ratio was set at 1.00, the accuracy rate, the sensitivity, the specificity, and the positive and negative predictive values of a C/R ratio below 1.00 for the differential diagnosis of diffuse-type carcinoma from intestinal-type carcinoma were 94.5%, 94.1%, 94.7%, 88.9% and 97.3%, respectively. IHb is useful for quantitative measurement of the endoscopic color in intramucosal gastric carcinoma and the IHb-C/IHb-N ratio would be helpful in distinguishing diffuse-type carcinoma from intestinal-type carcinoma.

  • To make vector data from a map which has no negative plates by using vectoring tool, it is necessary that we can extract objects to be vectorized from a scanned map. In this paper, we studied on extracting vectoring objects from scanned color maps. To do this, we classified vectoring objects into three types : line type, filled - area type and character/symbol type. To make the extraction method effective, we analyzed characteristics of vectoring objects and color distribution in scanned color maps. Then, we applied these characteristics to designing process of the extraction method. To extract the line type object, our line tracing method was designed by using the masks which considered connectivity and geometrical characteristics of lines. By using the local thresholding method and the similarity function for comparing the color distribution between two NxN blocks, we extracted character/symbol and the filled-area objects effectively. The method proposed in this paper can be used for constructing the small scale GIS application economically using existing color maps.

  • The purpose of this research is to study the visual characteristics of domestic national men's wear brand logos. For this purpose, 80 of national men's wear brands were selected from '2010/2011 Korea fashion brand Annual' For analysis, they were classified into three categories: logo types composed only with logomark or symbol and logomark together. Types of symbol were classified into word symbol, descriptive symbol, and abstractive symbol. And the used typefaces were classified into serif and san serif and acromatic and cromatic The results are as follows: The visual characteristics of domestic national men's wear brand logos, there were more brands that used logomark with symbol together than logomark only. And the type of symbols were appeared descriptive symbol(32% ) that meaned the men's power, nobleness and royalty. In domestic national men's wear brands, color of logos were more frequently used acromatic color as black and grey than cromatic color. Among the cromatic colors were more appeared to a kind of blue and green. And the used typefaces were the more frequently used to serif typeface of capital. As a result, the visual characteristics of domestic national men's wear brand logo were that they used the brand logos composed of descriptive logomark with symbol together, black serif typeface the most. From this results, we could find that visual stragety of domestic national men's wear brand logos had the tendency to emphasize the function of conveying information, brand concept that men's wear.

  • There are four types of human beings according to the Sasang Typology, Oriental medical doctors frequently prescribe healthcare information and treatment depending on one's type, The feature ratios (Table 1) on the human face are the most important criterions to decide which type a patient is. In this paper, we proposed a system to extract these feature ratios from the people's side face, There are two challenges in acquiring the feature ratio: one that selecting representative features; the other, that detecting region of interest from human profile facial image effectively and calculating the feature ratio accurately. In our system, an adaptive color model is used to separate human side face from background, and the method based on geometrical model is designed for region of interest detection. Then we present the error analysis caused by image variation in terms of image size and head pose, To verify the efficiency of the system proposed in this paper, several experiments are conducted using about 173 korean's left side facial photographs. Experiment results shows that the accuracy of our system is increased 17,99% after we combine the front face features with the side face features, instead of using the front face features only.

  • In this paper, we present a real-time eye contact system for realistic telepresence using a Kinect depth camera. In order to generate the eye contact image, we capture a pair of color and depth video. Then, the foreground single user is separated from the background. Since the raw depth data includes several types of noises, we perform a joint bilateral filtering method. We apply the discontinuity-adaptive depth filter to the filtered depth map to reduce the disocclusion area. From the color image and the preprocessed depth map, we construct a user mesh model at the virtual viewpoint. The entire system is implemented through GPU-based parallel programming for real-time processing. Experimental results have shown that the proposed eye contact system is efficient in realizing eye contact, providing the realistic telepresence.

  • Study on how a visual image of sex-appealing advertisement is meaningfully functioned and how customers recognize it is necessary but preceding studies about it are not sufficient. Therefore, this study analyzed effect of advertisement and its reaction according types of visual expression in sex-appealing advertisement and also, it found effective expression type of sex-appealing advertisement. As the result, according to appealing types of eroticism and pornograph, attitude on advertizement and intention of purchase showed difference and according to expressing types, there was difference in attitude on advertisement, attitude on brand, and intention of purchase. But there was not interactive effect between appealing type and expressing type. Such results implied that in using eroticism advertisement strategy, white and black color had higher expressing effect than natural color, to raise effect of brand, artistic sense and eroticism strategy were needed, and to raise intention of purchase, naked expression of pornograph was more effective.

  • Cloud detection and analysis from satellite images has been a topic of research in many atmospheric and environmental studies; however, it still is a challenging task for many reasons. In this paper, we propose a new method for cloud-type classification using fuzzy logic. Knowing that visible-light images of clouds contain thickness related information, while infrared images haves height-related information, we propose a two-layered fuzzy logic based on the input source to provide us with a relatively clear-cut threshold in classification. Traditional noise-removal methods that use reflection/release characteristics of infrared images often produce false positive cloud areas, such as fog thereby it negatively affecting the classification accuracy. In this study, we used the color information from source images to extract the region of interest while avoiding false positives. The structure of fuzzy inference was also changed, because we utilized three types of source images: visible-light, infrared, and near-infrared images. When a cloud appears in both the visible-light image and the infrared image, the fuzzy membership function has a different form. Therefore we designed two sets of fuzzy inference rules and related classification rules. In our experiment, the proposed method was verified to be efficient and more accurate than the previous fuzzy logic attempt that used infrared image features.
