A color filter array (CFA) helps a single electrical image sensor to recognize color images. The Red-Green-Blue (RGB) Bayer CFA is commonly used, but the amount of the light which arrives at the photodiode is attenuated with this CFA. Red-White-Blue (RWB) CFA increases the amount of the light which arrives at photodiode by using White (W) pixels instead of Green (G) pixels. However, white pixels are saturated earlier than red and blue pixels. The pseudo multiple capture scheme and the corresponding RWB CFA were proposed to overcome the early saturation problem of W pixels. The prototype CMOS image sensor (CIS) was fabricated with $0.35-{\mu}m$ CMOS process. The proposed CIS solves the early saturation problem of W pixels and increases the dynamic range.

The purpose of this study is to analyze the recent trend color of bathroom based on analysis result of digital color image processing, to analyze the emotional color of that, and to suggest the harmony color combination for the bathroom. It leads to the two final results. That is, the main color of bathroom image is recognized as three color classifications such as YR-Y, Y-GY, PB-P, 2) from the point of emotional aspect, the trend color of the bathroom can be classified into four image categories: 'modern', 'mild', 'elegant', 'natural'. Finally, under these categories, this paper propose 12 color harmony schema which can be applied to color in, especially bathroom Interior design.

The purpose of this study is to link traditional patterns to modern clothing. Of all the traditional patterns, the cloud pattern was chosen for use during the development of a modern one-piece dress design. This study is based upon document searches, including research papers. Through these searches, it investigates the symbolic meaning, historical change, and formation of the cloud pattern. Based on this investigation, the study attempts to modernize the cloud pattern and apply the modernized patterns to the design of a one-piece dress. The design procedure includes three sub-processes: selection, arrangement, and color-scheme. The selection process was divided in two: first, the original form of the cloud pattern was hand-drawn using tracing paper: second, the form of the pattern was edited using Adobe Photoshop. The arrangement of the pattern was made through the checklist conception method, containing the following functions: expand, reset, repeat, and overlap. For the color-scheme of the pattern, Roy Lichtenstein's(1923~1997) work was selected, and the colors in his work were adopted when dyeing the rest of the one-piece dress as well as the cloud features. In conclusion, six modern designs of the one-piece dress were created by using one of Korea's traditional patterns - the cloud pattern. Therefore, this study can offer invaluable suggestions for multifaceted research on how to come up with design concepts which apply Korea's traditional patterns to clothing design.

The purpose of this study is to link traditional patterns to mordern clothing. Of all the traditional patterns, the fish pattern was chosen for use during the development of a creative one-piece design for woman and shirts design for man. This study is based upon document searches, including research papers. Through these searches, it investigates the symbolic meaning, formation of the fish pattern and the creative design process. Based on this investigation, the study attempts to modernize the fish pattern and apply the fish patterns to the design of a one-piece dress and shirts. The design procedure includes three sub-processes: selection, arrangement and color-scheme. The selection process, the form of the pattern was edited using Adobe Photoshop. The arrangement of the pattern was made through the checklist conception method, containing the following functions: expand, reset, repeat, omission and dismantling. For the color-scheme of the pattern, Paul Klee(1879-1940)work was selected, and the colors in his work were adopted when dyeing the rest of the one-piece dress and shirts as well as fish features. In conclusion, six designs of the one-pieces dress and shirts were created by using one of Korea's traditional patterns-the fish pattern. This kind of study not only let the world know about the unique beauty of nations but also helps to inspire people who has a profession in design, by suggesting design development process based on design competitiveness improvement factor from fusion of tradition and modern.

본 논문은 컬러 인접성과 클러스터링 기법을 이용한 객체 기반 영상 검색 기법을 제안한다. 컬러 인접성이란 영상내의 서로 이웃한 영역에서 나타나는 컬러의 특징값을 말하고, 영상 데이터베이스로부터 사용자가 찾고자하는 영역과 유사한 후보 영역들을 우선 추출하는데 사용된다. 또한 클러스터링 기법은 후보 영역들 가운데 객체가 존재하는 영역만을 추출하는데 사용되고, 질의 영상과 데이터베이스 영상 사이의 유사도 측정을 위하여 히스토그램 인터섹션(histogram intersection) 방법이 사용된다. 제안하는 방법에서 사용되는 영상의 컬러쌍 정보는 객체의 이동, 회전 그리고 크기 변화에 강건하며, 실험을 통하여 제안하는 방법이 기존의 방법보다 우수함을 확인하였다.

This study compares and analyzes the designs of Burberry creative directors, Christopher Bailey and Riccardo Tisci. For this purpose, 322 photographs (176 Christopher Bailey and 146 Riccardo Tisci) were collected and the data analysis criteria were classified into color, shape, material, decoration, item, and fashion style. With respect to the data analysis method, statistical analysis and content analysis were combined. First, the design characteristics of Christopher Bailey top and bottom combined bright tone, tone-in-tone color scheme, H-line, heterogeneous material combination, and smart casual appeared very frequently. Second, the design characteristics of Riccardo Tisci top and bottom combined were monotone, tone-on-tone color scheme, H-line, heterogeneous material combinations, and street culture. Third, the design differences between creative directors were significantly different in color, tone, color arrangement, pattern, material type, material combination, detail, top and bottom items, and fashion style. Burberry men's wear maintains Burberry's traditional design identity with achromatic colors, beige-based colors, and beige checks. Christopher Bailey's design direction is characterized by modernity in a casual mood that emphasizes practicality. The design direction of Riccardo Tisci is characterized by a wide gap between images in a semi-formal style that emphasizes Burberry's tradition and a free-spirited casual style.

A new color image segmentation scheme is presented in this paper. The proposed algorithm consists of image simplification, region labeling and color clustering. The vector-valued diffusion process is performed in the perceptually uniform LUV color space. We present a discrete 3-D diffusion model for easy implementation. The statistical characteristics of each labeled region are employed to estimate the number of total clusters and agglomerative hierarchical clustering is performed with the estimated number of clusters. Since the proposed clustering algorithm counts each region as a unit, it does not generate oversegmentation along region boundaries.

색상 양자화는 각 픽셀의 색을 가장 가까운 대표색으로 치환함으로써 결과 영상을 단일 색상 영역들로 분할한다. 따라서 색상 양자화된 영상에서는 연속적이며 세부적인 색상 변화가 사라지게 된다. 본 논문에서는 색상 양자화 방법에 대한 선행 지식 없이 이러한 색상 변화를 자동으로 또는 대화적으로 복구하는 새로운 영상 역양자화 기법을 제안한다. 본 논문에서 제안한 기법은 입력 영상의 단일 색상 영역들 중에서 어떤 영역들끼리 결과 영상에서 연속적인 색상 변화를 가져야 할 것인지 식별한 후, 대표색을 유지하면서 이음새 없이 매끄럽게 연결한다. 또한, 대화형 브러시를 이용하여 어떤 영역들을 매끄럽게 연결할 것인지 또는 분리할 것인지 추가적으로 명시할 수 있게 한다. 사진, 만화, 예술적 삽화 등의 다양한 예제에 대한 실험을 통하여 제안한 영상 역양자화 기법의 유용성을 보인다.

본 논문에서는 컬러 영상을 위한 하이브리드(hybrid) 디지털 워터마킹 기법을 제안한다. 즉, 두 개의 워터마크가 주파수 영역과 공간 영역 상에 각각 삽입된다. 첫 번째 워터마크는 영상 데이터를 DW(discrete wavelet transform)를 사용하여 주파수 공간으로 변환한 후, 인간의 시각이 밝기에 민감하지 않다는 사실을 이용하여 컬러 영상의 밝기(luminance) 성분에 대역확산(spread-spectrum) 방법으로 워터마크를 삽입한다. 삽입되는 워터마크는 유사난수 패턴(pseudo-random pattern)을 사용하며 워터마크 검출시에는 상관도(correlation)를 이용하여 워터마크를 추출한다. 두 번째 워터마크는 첫 번째 워터마크가 클로핑(cropping)과 같은 기하학적 공격(geometrical of attack)에 취약한 점을 보완하기 위해 삽입한다. 영상의 공간 영역에서 블루 채널 상에 두 번째 워터마크가 삽입되며, 이때 영상의 특징점의 픽셀값을 입력 값으로 하여 해쉬함수의 출력값을 구한다. 따라서 두 번째 워터마크는 영상의 위 변조를 판별할 수 있는 tamper defection의 기능을 한다.
