It has long been speculated that the visual system should use a coding strategy that takes advantage of statistical redundancies in images. But how such a coding strategy should manifest in neural responses has been less clear. Low-level image structure related to the power spectrum of natural images appears to be captured by a hard-wired efficient code in the retina of the fly and precortical structures like the LGN of cats that maximizes information content through the limited capacity channel of the optic nerve. But visual images are typically filled with higher-order structure beyond that captured by the power spectrum and visual cortex is not constrained by the same capacity limits as the optic nerve. Whether and how visual cortex can flexibly code for higher order redundancies is unknown. Here we show using psychophysical techniques that the neural response in early human visual cortex may be modulated by orientation redundancies in images such that a visual feature that is contained within a predictive pattern results in slower reaction times than a feature that deviates from a pattern, suggesting lower neural responses to predictable stimuli in the visual cortex. Our results point to a neural response in early visual cortex that is sensitive to global patterns and redundancies in visual images and is in marked contrast to standard models of cortical visual processing.

The purpose of this study is to clarify the relationship between the visual sensibility and the decorative design of clothing. 41 kinds of costume samples have been selected from photographs in fashion magazines under detail and trimming, and divided into three types according to line, shape, and form. I have measured these images by using Semantic Differential method. The obtained data were analyzed by factor analysis ANOVA, discriminant analysis, regression analysis and MDS. The results of analysis are as follow; 1. Factor analysis has extracted five factors which consist of decorative design sensibility. These factors are Attractiveness, Hardness and Softness, Rhythm, Decorativeness, Cuteness. 2. There were significant differences in visual evaluation of decorative design and demographics 3. The discrimination among formative designs was closely related to decorative image, especially between line and form. 4. The Image effect on Preference, Buying needs, Riches and Pleasant was consist of complicated sensibility. 5. Evaluative dimensions of decorative design were identified by Simple-Complicated, Cubic -Plane perceptive image differed in degree of similarity in spite of same formative design.

As the online shopping mall market faces severe competition, marketers have focused on visual factors that generate positive consumer responses in order to induce more consumers. Although product photos are crucial in the communication of product information as well as in the development of positive images of online shopping mall, there was little intention the effect of diverse types of product photo. In this study, three types of backgrounds (i.e., no background, indoor background, street background) are compared in order to explore whether consumer sensibility factors are different according to photo backgrounds. Moreover, it investigates the effect of sensibility toward photo backgrounds on consumer attitude. A total of 222 consumers participated in the experiments. As a result, six sensibility factors were generated from online model photos, including structure, upscale, uniqueness, interest, simpleness, and easiness factors. Among these factors, simpleness and structure showed the highest means; simpleness was the factor indicating the differences according to photo backgrounds. Sensibility factors affecting attitude toward online shopping malls were uniqueness in the case of no background, interest in the case of indoor background, and upscale in the case of street background photo.

The algorithm developed in this paper allows us to generate or synthesize a large amount of data sets using only a small amount of signal features obtained from the original data set. Because the simulated density profiles of yarns retain the original features without a significant loss of information on the location of imperfections, the resulting fabric images are likely to resemble the original images. The data expansion system developed could generate a large area of fabric images by combining the Monte Carlo simulation and the wavelet sub-band exchange algorithm developed. The system has proven effective for simulating realistic fabric images by retaining the location of imperfections such as neps, thin and thick places.

본 연구는 사상관련전위를 이용하여 의식하에 제시된 미적자극이 대뇌활동에 미치는 영향을 밝혀내고자 이루어졌다. 이를 위해, 16명의 실험참가자에게 masking법를 이용해 미적자극을 의식하에 제시하였다(10msec). 제시된 자극은 선행연구를 통해 선정된 Beautiful Images(미자극), Ugly Images(추자극), Neutral Images(중성자극)이였다. 사상관련전위(event-related potentials; ERPs)는 64채널의 뇌파계를 이용하여 측정하였다. 그 결과, 후두엽 (Oz) 및 좌측두엽 (T5)에서 미자극에 의해 나타난 ERPs초기성분인 P1, N1, P2, N2의 진폭이 중성자극에 의해 나타난 진폭보다 컸다. 그리고, 후두염에서 추자극에 의해 보여진 P2, N2의 진폭 및 Late Slow Wave(LSW)의 평균전위가 중성자극에 의해 보여진 것보다 컸다. 이와 같은 ERPs성분은 자극의 탐지, 패턴인지, 기억탐색, 표적선택 등과 같은 자극의 정보처리와 관련되어 있다고 보고되고 있다. 따라서, 의식하에 제시된 미적자극은 서로 다른 대뇌 활동을 일으킴을 알 수 있다. 이는 인간은 의식하에서 미적자극에 대한 정보처리를 하는 기능을 가지고 있음을 뜻한다.

The purpose of this study was to investigate the female college students' preferences to the images of both western and eastern pictures, and positive/negative perception on to the model's nationality in the apparel advertizing pictures of fashion magazines. 100 students participated in the survey, and 20 stimulus pictures were shown to them. The results were as follows: The female college students preferred the western images than the eastern images in the pictures of bedroom, palace and beer, while they preferred the eastern images in the pictures of snack and famous drawings of a beauty. But they showed more positive attitude to all the western models' advertizement pictures than the eastern models' ones, in casual wear, formal wear, watches and inner-wear divisions except in men's formal wear division. This meant that the perception of female students on western images was positive and it seems stimulating the consumers preferences of brand images.

The affective words on photographic images were analyzed and a model was structured. Based on this model, the effects of color on the affections were studied. In study 1, the photographic images with various materials and techniques were presented and the affective responses are collected. The factor analysis using principal axing method showed that the variance of the affective words could be explained about 42％ by the three factors. These are named positive-negative, dynamic-static, light-heavy, respectively. In study 2, the effects of color on the affections were evaluated on three basic dimensions. Ninety representative color images were converged black-and-white images, and each of 180 images was rated on the three affective scales. The t-test showed that the effects of color are statistically significant on the three affective scales, respectively. The achromatic images were felt more negative, more static, and heavier than chromatic images.

In women's clothing the shoulders are distorted and exaggerated. Consequently, the wearers' bodies are transformed and interpreted according to modern standards. We therefore refer to this aspect of women's clothing as the power shoulder. This study aims to analyze the differences in sensibility images on variations in the shoulder shape of power shoulder jackets. Nine samples were examined that involved combinations of three variations of the shoulder height and three variations of the shoulder width. The data was evaluated by 123 fashion design majors. Four factors were selected: attractiveness, personality, activity, and self-respect. Among these factors, attractiveness is the most important. The study results indicated that changes in shoulder height acted as a major effect that had an independent influence on all four factors. In contrast, changes in shoulder width acted as a major effect that had an independent influence on attractiveness, personality, and activity but not on self-respect. It also had an influence on the interaction effect of attractiveness, personality, activity, and self-respect. We anticipate that this study will help individual customers select clothing that is suitable for their preference and body shape because it is now possible for them to estimate images of power shoulder jackets.

In this study, an eye-tracking program that can confirm a design cognition process was developed for the purpose of presenting strategic methods to create fashion images, and the program was used to identify what effects fashion models' external characteristics have on the cognition of design. The data for analysis were collected through an eyemovement tracking experiment and a survey, with the focus on the research problem that differences in models' external uniformity will lead to differences in the eye movement for perceiving models and design as well as the image sensibility. The results of the analysis are as follows. First, it was confirmed that the uniformity of model types and the simplicity/complexity of design led to differences in the eye movement directed at design and models and the gaze ratio. Consequently, it is deemed that models should be selected in consideration of the characteristics of design and the intention of planning when creating fashion images. Second, it was found that in terms of the cognition of design, external conditions of models affect design sensibility. A change in models led to a subtle difference in sensibility cognition even when the design condition did not change. Thus, not only the design but also model attributes are factors that should be considered important in fashion planning.

Recntly many devics print electronic images in a variety of ways. But the reproduced color, gamut mappung method and expanded nonlinear quantization are proposed. The color gamut mapping uses saturation mapping of HSI color space. Dithering operation for printing uses expanded nonlinear quantization which considers overlapping phenomena of neighboring printing dots. So the printed image is similar to the image of monitor and can produce high quality image in the low bit color devices.
