색의 기본이 되는 구성 요소는 색상, 명도, 채도로 정의된다. 시지각 특성을 기초로 연구한 먼셀 표색계의 경우 색상(Hue), 명도(Value), 채도(Chroma)로 분류하였으며 세 가지 속성에 대하여 기록하는 방법에는 시감에 중점을 두어 색표를 기준으로 기록하는 현색계와 수치상으로 정확하게 기록하여 변색 우려가 없는 혼색계로 구분할 수 있다. 색을 전달하고 표현하는데 있어 색채 용어는 매우 중요하게 사용되며 색채는 색상, 명도, 채도의 조합에 따라 색상을 구분하고 정의할 수 있다. 현재 다양한 미디어 매채의 개발로 인해 이전에 구현할 수 없던 색의 범위까지 표현할 수 있게 되었으며 디지털 중심의 색채 연구가 좀 더 세분화 되어 색채를 지각하는 특성에 대한 기초연구가 필요하다. 본 연구는 디스플레이에서 시지각 기반 먼셀 표색계의 대표 10가지 색상을 대상으로 각 색상을 인지하는 명도와 채도의 범주에 대해 알아보고자 정신물리학 실험을 진행하고 이를 분석하였다. 본 연구는 진행된 실험 결과를 분석하여 색채 인지 특성에 대한 기초 연구 자료로써 유의미 여부를 정의한 후 향후 연구방향을 제시한다.

The goal of this research is a visual and auditory tool development enabling designers to have the same emotional value with users in the process of user centered design. Through the research, we intend to show the aid measure for making cognitive gaps narrow between users and designer in the process of transforming and understanding the emotional needs as a verbal image. because In the business practice of design, most of tools and techniques for assessment and analysis of emotional needs are those used usually in the marketing fields. So the information generated and transformed from users to designers have a form of physical words. When the designer's understanding of the emotional needs is considered as a product mediated communication process, the morphologic and cognitive information gaps become obvious. This difference could be a false basis in designing with emotional user needs. So the alternative needs assessment sub-tools of visual and auditory information form was embodied mainly for designer's cognitive gaps and inter-cultural emotional needs assessment. As the method of embodiment, Firstly, adjectives related to emotion were classified in their cognitive dimension. Secondly, visual and auditory data were extracted, and then the relativity verified. Finally, the practicality and effectiveness were tested through the database generation. In view of the results so far achieved, 1. We could find being of the big information cognitive gaps in the verbal assessment of emotional needs between designers and users. 2. With the visual and auditory assessment tool, we could make the big cognitive gaps narrower than we expected. 3. Also, we could find the chance that the fidelity, recognition, and friendliness of design for emotional user needs would become better.

This paper deals with problem of determining process target value under automated visual inspection(AVI) system. Three independent error sources - digitizing error, illumination error, and positional error - which have a close relationship with the performance of the AVI system, are considered. Assuming that digitizing error is uniformly or normally distributed and illumination and positional errors are normally distributed, respectively, the distribution function for the error of measured lengths is derived when the length of a product is measured by the AVI system. Then, Optimal target values under two error models of AVI system are obtained by minimizing the total expected cost function which consists of give away, rework and penalty cost. To validate two process setting models, AVI system for drinks filling process is made up and test results are discussed.

An improved algorithm for image quality assessment is presented. First a simple model of human visual system, consisting of a nonlinear function and a 2-D filter, processes the input images. This filter has one user-defined parameter, whose value depends on the reference image. This way the algorithm can adapt to different scenarios. In the next step the average value of locally computed correlation coefficients between the two processed images is found. This criterion is closely related to the way in which human observer assesses image quality. Finally, image quality measure is computed as the average value of locally computed correlation coefficients, adjusted by the average correlation coefficient between the reference and error images. By this approach the proposed measure differentiates between the random and signal dependant distortions, which have different effects on human observer. Performance of the proposed quality measure is illustrated by examples involving images with different types of degradation.

Much research has been conducted to judge aesthetic value for a single type of stimuli, but research to determine aesthetic value when two kinds of stimuli are presented at the same time is not explored in depth. In this paper, we measure the difference between the presentation of visual stimuli like general image and the presentation of signboard image including text stimuli using EEG. In the experiment, two oddball tasks were performed for general images and signboard images, and EEG changes according to the aesthetic value of the images were measured. As a result, the change of ERP in signboard image was larger than that of general image. We confirmed that more visual information was received and processed when two stimuli were presented at the same time.

This study has analysed the characteristics of observation by presence of objects in exhibition spaces through eye-tracking. The area with prevailing observation by the change of observation time with visual-perception response to the presence of objects has been analyzed to figure out the mechanism of sensibility estimation which can take place while the visual-perception is being estimated in spaces. Research results are able to ascertain that First, it was very characteristic that the signs right and left were observed more when there were no objects while when there were objects they were observed prevailingly. Second, the characteristics by section when there were any objects showed that there were more high observation scale I (more than 1000ms). When there were any objects with the number of areas where all the participants prevailed commonly, the scale was more, also. Third, in the process of acquiring any visual-perception information in spaces, the element of landmark can be regarded as a control point for space cognition, where the objects (people) became landmark when there were the objects but the signs became landmark when there were no objects. Fourth, the polynomial trend line of the changes to prevailing observation frequency by observation time shows that there was a gradual average value in general when there were any objects and then after the time range[8] the prevailing observation frequency increased. Without any objects, after a particular time range the value sharply dropped along with the increase of observation time because no objects to be observed prevailingly couln't be seen. The gradual average value means that some elements in the space were prevailingly observed all the time.

Animation is a field of popular visual art that is established in human life, and the form of characters appearing is an important factor that is highly anticipated by the public. Designing animation characters according to aesthetic characteristics not only satisfies people's aesthetic needs but can also increase their artistic immersion in animation works. In addition, animation storytelling is delivered around characters and enhances the value of the work by encouraging more public to focus on it. In this paper, we tried to analyze the design elements of Minions characters to derive the reason why they are loved by the public. Among the morphological characteristics of bicepsin characters, a study was conducted on the fact that bicepsin characters visually express 'cute' through the study of infantile eating and color. The visual cuteness elements of a bisung character will soon be linked to the psychological satisfaction of the audience's work and will be a factor in the appreciation of the value of the work. By studying the elements of expression that represent isosin characters, I would like to discuss the factors that help the audience to immerse and get satisfaction with the characters. This will be used as an important factor for an animation character to have for the audience and will reveal its value. Second-class animation images belong to the art of small pieces, suitable for all the audience to enjoy. The two-size animated image has a strong appeal and entertainment, is a confusing visual attribute, can stimulate the audience's five senses. Compared with the actors in the movie, the visual form of the animation is more important.
