Preliminary results are reported on ship detection using coherence images computed from cross-correlating images of multi-look-processed dual-polarization data (HH and HV) of ENVISAT ASAR. The traditional techniques of ship detection by radars such as CFAR (Constant False Alarm Rate) rely on the amplitude data, and therefore the detection tends to become difficult when the amplitudes of ships images are at similar level as the mean amplitude of surrounding sea clutter. The proposed method utilizes the property that the multi-look images of ships are correlated with each other. Because the inter-look images of sea surface are covered by uncorrelated speckle, cross-correlation of multi-look images yields the different degrees of coherence between the images and water. The polarimetric information of ships, land and intertidal zone are first compared based on the cross-correlation between HH and HV. In the next step, we examine the technique when the dual-polarization data are split into two multi-look Images.

The importance of souvenirs are increasing immensely these days owing to the increase of foreign visitors to our country, which forces us to turn our eyes to this field. Upon these reflections, this study aims at aims at developing cap designs that satisfy the foreign tourists needs and let them recognize the outstanding beauty of Korean traditional patterns by applying traditional motifs. The Korean traditional patterns and their symbolic meanings were researched as well as the previous studies on the designing of goods for foreign visitors which had traditional patterns applied. Furthermore, the overall tendencies of the purchase of souvenirs and goods by foreign tourists in Korea as well as in foreign countries were investigated. Next, the present state of apparel goods and caps for sightseers in Korea was analyzed according to their shapes, colors, and patterns. Finally, by using CAD system, new cap designs were developed applying traditional bat motifs in order to capture the traditional images for a modern sense of beauty.

In order to preserve the seeds of excellent Hanwoo(Korean traditional cattle) and secure quality competitiveness in the infinite competition with foreign imported beef, production of high-quality Hanwoo beef is absolutely necessary. %IMF (Intramuscular Fat Percentage) is one of the most important factors in evaluating the value of high-quality meat, although standards vary according to food culture and industrial conditions by country. Therefore, it is required to develop a %IMF estimation algorithm suitable for Hanwoo. In this study, we proposed a method of estimating %IMF of Hanwoo using CNN in ultrasound images. First, the proposed method classified the chemically measured %IMF into 10 classes using k-means clustering method to apply CNN. Next, ROI images were obtained at regular intervals from each ultrasound image and used for CNN training and estimation. The proposed CNN model is composed of three stages of convolution layer and fully connected layer. As a result of the experiment, it was confirmed that the %IMF of Hanwoo was estimated with an accuracy of 98.2%. The correlation coefficient between the estimated %IMF and the real %IMF by the proposed method is 0.97, which is about 10% better than the 0.88 of the previous method.

This study is a theoretical research based on previous domestic and international researches. The case study proceeded by collecting images from periodicals such as International Men's magazine GQ, First of all website(www.style.com) and Vogue website(www.vogue.com) were viewed. The images were selected had shapes, colors, and motives with Japanese aesthetic traits from Comme des Garçons' men's Collections of 2011 F/W to 2016 S/S. The purpose of this study is to find out the possible sources of forms and expressive methods of future fashion through Japanese traditional aesthetics of Rai Kawakubo's fashion world. Designers are expected to continue on using traditional aesthetic beauties of other countries as sources of modern fashion.

In the fashion industry, the thing that shows the latest trends and makes issues is the fashion show. The function of fashion shows is changing from a promotional mean to a method of communication with customers. Recently, some fashion shows have used digital images and omitted traditional parts of a fashion show such as models, stages, garments, music and audiences. In this study, 30 fashion shows that used digital images were selected from the 2000-2010 collections of Paris, Milan, London and New York, and its communication characteristics were analyzed and discussed. The three categories of the communication characteristics are as follows: First, the shows used digital images as stage sceneries or effects to create desired stage effects. The digital images were used as extra tools to reinforce the concept of the fashion show. Second, the fashion shows used real-time videos to extend its presentation into the virtual space. The interactive videos were designed to encourage audiences to actively participate in the show. Third, the digital images were the focus of the show for the internet-only digital fashion shows. Since the Internet is not constrained by time or space, multi-faceted, communication between audiences and fashion designers or among audiences is possible. In addition, the number of audience it can reach is higher than traditional fashion shows. Digital images will be used more often in the fashion shows. In the future, fashion shows will try to become more interactive with audiences through the use of new digital image technology.

In the field of content-based image retrieval, various mathematical low-level features have been proposed to describe the perceptual content of images. Since most of the features are assumed to be independent of each other, one feature is extracted from images without any consideration of the other features. Recently proposed CCE and SCFT taking advantage of the correlation between color and texture have shown relatively good performance. In this paper, the performance of CCE, SCFT, and the traditional regular weighted comparison method are evaluated. Simulation results with natural images have shown that CCE outperforms the other methods.

This study examined the characteristics of costumes worn at Halloween parties, a form of cultural entertainment commonly seen in the U.S. The Halloween party culture involves children and adolescents wearing costumes, decorating their bodies, and mimicking famous characters. Furthermore, the types and motifs of Halloween costumes have become a means of expressing individuality. This study conducted empirical research on how such motifs were reflected in modern Halloween party-wear in order to provide basic data regarding the development and design of Halloween costumes and the formation of the related entertainment culture. This study researched the shape of costumes and the type of traditional motif presented in these costumes, as well as analyzed the symbolic meaning of each motif. The research process was as follows. First, this study investigated the origin and evolution of Halloween by researching precedent studies, books, and internet data. Second, this study extracted the types of traditional Halloween motifs by analyzing the characteristics and symbols of Halloween costumes commonly presented in such materials. After collecting 547 Halloween-related images from U.S. and Korean Internet websites, this study sorted and analyzed images that could represent traditional Halloween motifs. According to the results, representative traditional Halloween motifs included black cats, white rabbits, tridents, scarecrows, skull and bones, ghosts, witches, vampires, bats, werewolves, and jack-o-lanterns(pumpkins, etc.). The sentiments for such traditional Halloween motifs changed according to era and race. The symbolic meaning would continuously change - from positive to negative and vice versa - to reflect various socio-cultural phenomena. The results of this study are expected to be used as basic data for developing Halloween costume designs and the related entertainment culture.

This paper intends to find out any possibility that a traditional fan can be continuously used for design development of fashion cultural products which highlight the differentiated uniqueness of Korean traditional cultures. For this purpose, this paper will newly reinterpret design-based formative factors that the shape and the line of a traditional fan shows, and then, make a pattern. This paper studied the existing literatures of a traditional fan, made the shape of a traditional fan into a motif, using computer graphic programs, like Adobe Illustrator CS 2 and Adobe Photoshop CS2, and then, applied it to neckties, T-shirts, and scarves. Among various kinds of traditional fans this paper set 4 basic motifs of new formative images by use of the shapes of Dan-Seon and Jeob-Seon, and then, developed them into two basic motifs each. Pink, blue, purple, green, yellow, orange, and gray were used as the basic colors of the motifs, through which splendid, but calm images were planned. The design of a necktie, which used a developed motif design, was applied in the form of a repeated pattern, through which a calm image was expressed. 45o turn was applied to this design to make a striped pattern image or a refined and cheerful image. The scarf design was developed into a rectangular long scarf so it can be used like a shawl. The design of T-shirt was developed into three types: a round neck-lined half-sleeved box type; a round neck-lined sleeveless type; and a V neck-lined, tight half-sleeved type.
