The purpose of this study is to grasp the characteristics by image type in interior color. This experiment is carried out by the evaluation method of color simulation with the color image processor. And the result of this experimental evaluation is analyzed quantitatively by HAYASI 1 Program. The results of this analysis are as follows : 1) In casual and clear images, the most main colors are GY, PB, Y , and N, Casual image has high chroma and the most arrangement of colors is hue-contrast or contrast -harmony with white. Also the main colors of clear image are in identical or similar harmony with the hues of floor. 2) In romantic, elegant, pretty, and gorgeous images, the most main colors are GY, RP, R , YR and Y and the most arrangement of colors is identical or similar harmony. The romantic image of pastel tone is wholly lighter than the pretty image of bright tone. And elegant image is lower in chroma than romantic images, so generally dark. Also gorgeous image is the vivid tone with high chroma. 3) In chic and modern images, the main colors are the hues of B, PB, high value and low chroma with bright tone. Also, the main colors are in identical or similar harmony with the hues of floor : BG , B, PB and P. 4) In natural and semiclassic images, the main color is the warm color of Y, YR and the most arrangement of colors is identical or similar harmony. Also Semiclassic images is the dull tone with middle value and middle chroma and darker tone than natural image. 5) In dynamic image, the main color is the hue of N, Y, PB and GY and most of color is high chroma. And the most arrangement of colors is value-contrast.

본 논문은 특징을 효과적으로 병합하여 계층적 색인구조를 적용하는 광고영상의 분류기법에 대한 체계적 방법을 제안한다. 본 방법은 온라인 및 오프라인 상의 광고 영상 정보 관리를 위한 효과적인 응용으로써, 특별히 광고 영상정보의 추적을 위한 전처리 과정을 제공한다. 이를 위하여 전체 영상에 대한 일반적 정보를 포함하는 전역특징과 영상의 지역적 특성에 기반하는 지역특징을 고려한다. 고안된 지역특징은 영상 회전, 스케일링, 잡음추가, 빛의 변화에 불변하여 아핀(Affine) 변환에 의한 화면 차 영상에 대하여도 신뢰성 높은 매칭 도를 얻을 수 있고 동질의 영상 쌍을 검색하는데 있어서도 높은 정확도를 보여준다. 제안 방법은 우선 전역특징으로 전체영상자료에서 다수의 영상 쌍들로 개략적인 영상 군을 구성한 후에, 영상군안에서 지역특징에 의한 동질 영상 쌍들 즉 정밀한 영상 군들로 분리하는 정밀 매칭을 실행한다. 실행시간을 단축하기 위해 전형적인 클러스터링으로 전역특성이 유사한 영상들끼리 그룹화 함으로서 지역특징에 의한 동질 영상 쌍 간 과도한 매칭 시간의 문제점을 극복한다.

In this paper, we propose a ground plane detection algorithm, using a new image processing method (IPD). To extract the ground plane from the color image acquired by monocular camera, we use a new identical pixel detection method (IPD) and an edge detection method. This IPD method decides whether the pixel is identical with the ground plane pixel or not. The IPD method needs the reference area and its performance depends on the reference area size. So we propose the reference area auto-expanding algorithm in accordance with situation. And we evaluated the proposed algorithm by the experiments in the various environments. From the experiments results, we know that the proposed algorithm is efficient in the real indoor environment.

The main objective of this research was to understand the characteristics of identical color coordination through the analysis of modern female fashion color coordination as they appear in the 'Collections'. Data collection of 2026 was done through review of '$pr\hat{e}t-\grave{a}$-porter Collections' of four cities; Milan, London, New York, Paris. Lastly, statistical analysis of frequency and $X^2$-test and also qualitative interpretation of identical color coordination characteristics were completed. The main findings were; The color coordination of modern women's fashion produces a unified theme, or monochromatic harmony, through the use and coordination of identical colors. The clear contrast of tones portrays a strong image especially in achromatic color coordination, and through the use of texture variation, monochromatic color coordination becomes even more compelling. The tone variation, observed most often in monochromatic color coordination was the black and white contrast, which enhances the simplicity and clarity. Within chromatic color combinations, tone on tone color coordination was achieved by varying brightness. Furthermore, the observation of Faux Camaeu indicates that the coordination of different textures is used often in identical color coordination. While achromatic colors can lead to a hard and rough feeling, it also is compensated through the use of varying textures. In addition, adding variety of textures can add subtle interests to the simplicity of white. Lastly, in all four collections, the chromatic identical color coordination was found more frequently than the achromatic. In Paris, N.Y. & London, the chromatic identical coordination was used more often than chromatic. Milan showed most use of achromatic coordination. The use of the tones showed similar trends in all four collections, with contrasting tone being used most often, followed by similar and identical tones.

본 연구에서는 CD-RAD Phantom을 이용하여 의료영상의 명세성 (image clarity)분석을 위하여 동일한 X선 영상을 대상으로 물리적 평가와 시각적 평가를 비교분석 하였다. 측정방법은 CD-RAD Phantom을 X선 조사하여 CR 영상처리장치를 통해 영상을 획득하였으며, 영상분석은 CD-RAD analyser program을 통한 통계학적 방법으로 물리적 평가를 시행하고, 동일한 영상의 시각적 평가는 관찰자 20명을 대상으로 blind test를 시행하였다. 분석결과는 Contrast-detail curve의 물리적 평가 IQF값은 25, 시각적 평가 IQF값은 30으로 분석되어 물리적 평가가 시각적 평가에 비해 우수하게 나타났다. 의료영상의 특성은 영상 판독자에게 영상의 정보 전달능력이 매우 중요하므로 객관적인 물리적 분석법과 시각적 분석법이 병행되어야 한다고 판단된다.

A novel high speed VLSI architecture and its VLSI realization methodologies for a motion estimation processor based on full search block matching algorithm are presentd. The presented architecture is designed in order to be suitable for highly parallel and pipelined processing with identical PE's and adjustable in performance and hardware amount according to various application areas. Also, the throughput is maximized by enhancing PE utilization up to 100% and the chip pin count is reduced by reusing image data with embedded image memories. Also, the uniform and identical data processing structure of PE's eases VLSI implementation and the clock rate of external I/O data can be made slower compared to internal clock rate to resolve I/O bottleneck problem. The logic and spice simulation results of the proposed architecture are presented. The performances of the proposed architecture are evaluated and compared with other architectures. Finally, the chip layout is shown.

This paper concerned about a imputed color printed material image in camera to decrease noise and distortion by processing median filtering with input image to identical condition. Also this paper proposed the way of compares a normal printed material with an abnormal printed material color tone with trained a learning of the error back-propagation to block classification by extracting five place from identical block(3${\times}$3) of color printed material R, G, B value. As a representative algorithm of multi-layer perceptron the error Back-propagation technique used to solve complex problems. However, the Error Back-propagation is algorithm which basically used a gradient descent method which can be converged to local minimum and the Back Propagation train include problems, and that may converge in a local minimum rather than get a global minimum. The network structure appropriate for a given problem. In this paper, a good result is obtained by improve initial condition and adjust th number of hidden layer to solve the problem of real time process, learning and train.

In this paper, we concentrate on the mask design problem for optical micro-lithography. The pre-distorted mask is obtained by minimizing the error between the designed output image and the projected output image. We use the particle swarm optimization(PSO) and fuzzy system to insure that the resulting images are identical to the desired image. Our method has good performance for the iteration number by an experiment.
