  • In this paper, we propose a high-quality image acquisition algorithm using only a single image, which the high-quality image is normally referred as HDR ones. In order to acquire the HDR image, conventional methods need many images having different exposure values at the same scene and should delicately adjust the color values for a bit-expansion or an exposure fusion. Thus, they require considerable calculations and complex structures. Therefore, the proposed algorithm suggests a completely new approach using one image for the high-quality image acquisition by applying statistical difference and histogram manipulation, or histogram specification, techniques. The techniques could control the pixel's statistical distribution of the input image into the desired one through the local and the global modifications, respectively. As the result, the quality of the proposed algorithm is better than those of conventional methods implemented in commercial image editing softwares.

  • Surrealism's method of expression and inspiration has been a continuous influence on fashion. What is important is how to identify and research a source of inspiration, and how to use this inspiration to guide the designs that can be worn on a real human body. Therefore, the purpose of this study was to show how to develop ideas and designs from Surrealist objects and how to contribute to the development of designs to the diversity in visual and functional effects along with the changes in consumer's interest. Documentary studies about Surrealism and Surrealist-inflected fashion applying the works of Surrealist and fashion images as a tool of historical research were proceeded. And the ideas for theme, the motifs for print patterns, and the concept of designs were borrowed from Surrealist objects touching on the imagery between the real and reflected, optical and artificial, and the designs were developed with several different visual and functional effects changing color, pattern, size, and length with the function of zippers in each item. It also gives the person wearing it amusement because it includes the concept of play and D.I.Y. With effective planning, it is possible to attract consumer's interest in the market.

  • In this paper, we propose an adaptive image enhancement algorithm. The proposed algorithm is classified with the MIE technique for intensity enhancement of input image and MSE techniques for saturation enhancement. The MIE technique is proposed to control the gamut mapping problem and a sudden change in image-brightness while Luminance signal is processing, The MSE techniques are proposed to control de-saturation or over-saturation while chrominance signal is processing. The proposed algorithm is focused on processing preference color for human vision in order to generate better image quality than the algorithms focused on processing uniformly to whole images, This algorithm can be applied to a monitor, TV and other display devices for high quality image.

  • Socks and stockings played a role as the first clothing covering foots and legs in ancient times. During the Middle Age they have represented clothing for legs and have been transformed into plasticity and aesthetic outlets for human beings aesthetic desire. Recently in around 1980 various experiments have been tried on them as part of total fashion changing as fashion trends changes. In 1990s the industry of socks and stocking in Korea has grown up as niche market, increasing the export amount twice as much as before. Therefore, this paper reveals the plasticity through historical study of socks and stockings. The purpose of this research is to analyse the plasticity by image classification of socks and stockings in 1990s on the basis of historical studies, which will be the basic data for developing high value added products. The major plasticity features of socks and stockings are material, technic, formativeness, ornament, color in a word. In 1990s the images of socks and stockings are classified into romantic, sporty, ethnic, ecology, avant- garde image. In 20th century knit and nylon became common and the part of the total fashion, completing the whole fashion.

  • A multiple classification system based on a new boosting technique has been approached utilizing different biometric traits, that is, color face, iris and eye along with fingerprints of right and left hands, handwriting, palm-print, gait (silhouettes) and wrist-vein for person authentication. The images of different biometric traits were taken from different standard databases such as FEI, UTIRIS, CASIA, IAM and CIE. This system is comprised of three different super-classifiers to individually perform person identification. The individual classifiers corresponding to each super-classifier in their turn identify different biometric features and their conclusions are integrated together in their respective super-classifiers. The decisions from individual super-classifiers are integrated together through a mega-super-classifier to perform the final conclusion using programming based boosting. The mega-super-classifier system using different super-classifiers in a compact form is more reliable than single classifier or even single super-classifier system. The system has been evaluated with accuracy, precision, recall and F-score metrics through holdout method and confusion matrix for each of the single classifiers, super-classifiers and finally the mega-super-classifier. The different performance evaluations are appreciable. Also the learning and the recognition time is fairly reasonable. Thereby making the system is efficient and effective.

  • It needs more than two images which are obtained in real time to decide 3D positioning of dynamic object. Though we use digital camera which is became wide utilization, but it can't obtain sequential image. So, in this study, we constructed momentary image acquisition system using video camera. Also, we took a photograph of LCD timer and dynamic object together for real time stereo image, and we obtained independent digital image from sequential image using video editor. As a result of the study, we could obtain the independent image as true color digital image of $788{\times}550$pixels with 1/100sec accuracy in the same time. And it was good when we tested object target. For comparing 3D positioning accuracy, we could obtained negative with metric camera using B-shutter.

  • Modern fashion industry creates complex and multiple fashion by amalgamating and mixing all elements that emerged in fashion without limiting them to a specific genre. The results of study are as follows: First, with regard to the conceptual differences among poor look, anti-fashion, and resistance fashion and the background. second, As aesthetic categories of poor beauty, its image with the feeling of poorness, beggar-likeness, worthlessness, poorness, and uncleanness is divided into the beauty of moderation, deconstruction, unfinished beauty, natural beauty, and ostentatious poor beauty based on the formative characteristics and poor look. Third, Oriental and Western poor images are comparatively analyzed. The poor beauty found in Oriental fashion, which is based on Zen aesthetics, seeks loneliness, poorness, and simplicity as an empty origin and features internal meaning that expresses the purity of poor beauty itself and external form that is visualized through no decoration, no color, and asymmetry in material and composition. The poor beauty in the West features non-form of no shape, asymmetry and disharmony and the characteristic in its contents is "distortion", and the characteristic in its expression features external form of "incorrectness" and internal meaning implying modem humans' frustration, resistance to materialism, and skepticism about mechanicalism.

  • The purpose of this study is to investigate the effect of body type(thin, standard, fat), necktie width(narrow, medium, wide), gender(man, woman) on image formation. Sets of stimulus and response scales(7 point semantic) were used as experimental materials. The stimuli were 9 color pictures manipulated with the combination of necktie-width and body type using computer simulation. The subjects were 116 male undergraduates and 99 female undergraduates living in Gyeongsangnam-do. Image factor of the stimulus was composed of 4 different components, young-activity, attractiveness-gracefulness, stability, and boldness. In the young-activity, attractiveness-gracefulness and stability, body type and necktie-width showed independent effect. In the boldness, body type showed independent effect. Significant interaction effects of body type and necktie-width on young-activity, attractiveness-gracefulness and stability were found. For young-activity image, necktie of narrow width were effective. For attractiveness-gracefulness image, body type of standard were effective. For stability image, body type of standard and body type of thin on necktie of narrow and medium width were effective. The male fashion image can be perceived differently according to combination of the clues used in body type and necktie-width. Therefore, when the male fashion to create images that will have to consider the body type and necktie width.

  • The first zoeas of Parapanope euagora and Halimede fragifer hatched in the laboratory from two ovigerous galenid crabs of Pilumnoidea were collected from Jindo Island, Jeolanam-do, southern Korea. Their morphologies are described in P. euagora for the first time in the world and re-described in H. fragifer with the color images of live zoeas. In this study, they show a general morphology of Pilumnoidea by having a long antennal exopod, an endopod of the maxillule with 1, 2+4 setae, an endopod of the maxilla with 3+5 setae, and a fork of the telson with two lateral armatures. However, the first zoea of P. euagora differs from other known zoeas of pilumnoid species including H. fragifer by having a long antennal exopod with a medial seta and spine, not two spines, and a fork of telson with two lateral setae, not a seta and spine. Such characteristics of the antennal exopod and the fork of telson are reported for the first time in the pilumnoid zoeas. A comparison between the first zoeal stage of H. fragifer in this study and that of Terada shows minute differences in the characteristics of the antennule and the fork of telson.
