This study is intended to examine the common features of costume images in science-fiction (SF) movies that deal with current socio-cultural situations by examining their themes and tones about the future it can be generally concluded that costume images of SF movies are divided into two patterns : one inheriting traditional styles constructed on linear progress and the other based on dismantiling the tradition. this analysis is made through the research of actual cinematic contexts on the common features of multiple styles shaping the two patterns of costume images. The results can be summarized as the following: The former is related with the future built up on the basis of belief in reasonal progress rooted in the Enlightenment reasonable plan for ideal social order and strong faith in uniformity. So It shows functional uniformity disregarding wasteful competitiveness in consumption and luxuriousness and clothing that has the aesthetic value of purity without emphasizing human body or sensuality are presented. On the other hand SF movies which show the uncertain costume image as the meaning of dismantling of tradition take up a rather critical view of assumption that society can move toward utopian future as it searches future images in the notion of hetero-topia by emphasizing pluralism consequently as for clothing diversity and uncertainty in post-modern style are presented destroying modernistic dichotomy and the assumption of Utopian clothing made in the notion of modern progressivism.

본 논문에서는 복수 모델영상 간의 휘도치의 차이(이를 상위도라고 정의함)를 기본으로 영상매칭의 기준이 되는 "상위도 패턴"을 만드는 방법과, 이를 이용하여 입력영상과 모델영상간의 거리 계산에 의해 손의 형상을 인식하는 알고리듬에 대해 기술한다 이 방법의 특징은 인식과정에서 에지나 코너 등과 같은 기하학적 형상특징을 이용하는 것이 아니고, 영상전체를 하나의 처리단위로 하여 다수의 영상으로부터 구한 단순한 휘도치 차이를 2차원의 형상으로 패턴화 하여 인식과정에 사용한다는 점이다. 따라서 대량의 모델이 상호간에 갖는 상관관계가 인식과정에서 동시에 적용되기 때문에 대규모의 영상을 비교할 필요가 있는 인식 알고리즘의 실현에 매우 적합하다.

The aim of this study is to select MLMA and Noen Eubanks as representatives of Gen Z's unique subculture 'E-girl' and 'E-boy' to analyze fashion images and determine their meaning through the perspective of persona. To conduct this study, a literature review and case studies were combined and fashion images of E-girl and E-boy appearing on social media were analyzed to identify the personas they expressed. A case study of MLMA and Noen Eubanks' Instagram and TikTok account posts showed that grotesque, kitsch, and gender-related images stand out. The digital personae demonstrated by E-girl and E-boy fashion images were demonstrated to be a strange persona that reject perfect beauty and a playful persona escaping from reality and anxiety. Lastly persona of individual identity was shown to be formed. This study provides a basis for understanding and interpreting Gen Z's culture and aesthetics that will lead to future trends. Based on this study, I hope that various studies on E-girl and E-boy apparel will be conducted, and that by understanding the importance of E-girl and E-boy culture for Gen Z (which is paying attention to fashion trends), this can be used as a marketing strategy to consider their characteristics, with data used to inform design development.

Dual-energy X-ray imaging (DEI) techniques can provide X-ray images that a certain material is suppressed or emphasized by combining two X-ray images obtained from two different x-ray spectrum. In this paper, a single-shot DEI, which uses stacked two detectors (i.e., multilayer detector), is proposed to reduce the patient dose and increase throughput in angiography. The polymethyl methacrylate (PMMA) and aluminum (Al) were selected as two basis materials for material decomposition, and material-specific images are reconstructed as a vector combination of these two materials. We investigate the contrast and noise performance of material-decomposed images using iodine phantoms with various concentrations and diameters. The single-shot DEI shows comparable performances to the conventional dual-shot DEI. In particular, the single-shot DEI shows edge enhancement in material-decomposed images due to the different spatial-resolution characteristics of upper and lower detectors. This study could be useful for designing the multilayer detector including scintillators and energy-separation filter for angiography purposes.

This paper presents a method of estimating 3-D surface geometrical features that are necessary for 3-D object recognition and image interpretation. The features, such as surface needle maps and curvatures, are computed from range or intensity images. In general, the range and intensity images are prone to noises, and hence the features computed by differentiation calculi on such a noisy image are hardly applicable to industrial recognition tasks. In our approach, we try to obtain a more accurate estimate of the features by using a least-squares minimization procedure subject to local curvature consistency constraints. The algorithm is robust with respect to noises and is completely independent of the viewpoint at which the image is taken. The performance of the ajgoritlim is evaluated using both synthetic data and real intensity images.

This thesis, concerning Femme Fatale Images Costume Form in paintings viewed from DeLong's Theory, analyzed frequency and traits on the basis of DeLong's Form Observation Theory and drew out the result as followings. First, Costume Form was mostly open, whole, planer integration, rounded, and indeterminate. The styles were similar each other. Second, surface structure was expressed by line & shape, color, texture, and pattern of which color had the highest priority. Next, line & shape and texture had the priority in order. They were expressed through intereaction. Third, the traits of Costume Form were a similar color harmony or large light and darkness contrast+soft quality+interaction by ambiguous line & shape. So, Femme Fatale Image in paintings was expressed by soft and pure images and erotic images.

The frequency of car accidents is very high at the intersection. Because of the state of a traffic signal, quarrels happen after accidents. At night many cars run away after causing an accident. In this case, accident analyses have been conducted by investigating evidences such as eyewitness accounts, tire tracks, fragments of the car or collision traces of the car. But these evidences that don't have enough objectivity cause an error in judgment. In the paper, when traffic accidents happen, the traffic accident detection system that stands on the basis of images and sounds detects traffic accidents to acquire abundant evidences. And, this system transmits 10 seconds images to the traffic center through the wired net and stores images to the Smart Media Card. This can be applied to various ways such as accident management, accident DB construction, urgent rescue after awaring the accident, accident detection in tunnel and in inclement weather.

Estimation and correction of color temperature of digital images are basis of white balance adjustment after image acquisition stage. White balance is one of the most important image processing techniques for subjective image quality enhancement. Correction of color temperature is applied for white balance adjustment or for changing the mood of a picture. A picture taken under the daylight can be changed to have a mood of sunset or cloudy day, for example. We evaluate color temperature transformation of high dynamic range images in linear and log domain, and we conclude that linear domain transformation shows better results.
