This study was intended to make an inquiry into the effect of lines, shapes and colors (achromatic colors) as apparel design elements on the perceptions of facial size, brightness and shape through an empirical research based on the theories of visual perception and optical illusion that have been studied in Gestalt Psychology, which becomes the basis of apparel design principles. It was shown that the facial size was influenced by the collar size, the degree of neckline cut, and the thickness of the trimming line. The white scarf with the white jacket made the face look darkest while the black scarf with the black jacket made the face look brightest. When the neckline had the characteristic of the line contrasted with the facial shape, the oval-shaped face was perceived to be the most ideal. When the facial shape and the neckline shape were similar, the facial shape was perceived to be more highlighted.

Anamorphosis is highly favored in modern days as the atmosphere of pursuing unusual manners is growing while transformation and distortion of images are freely available. This research is to understand the affect of these distorted images on space designs and the close connection between anamorphosis and visual perceptions, and to identify the new perceptual phenomenon created through it, and the methods of expressing those. Four expressional methods were defined through the process of studying Anamorphosis based on its definition by Niceron, examining artworks such as paintings and photographs, and case-studying example spaces of visual perception experiments. Expressing anamorphosis through visual perceptions are broadly categorized to directional, dimensional, flatness, and optical. The analysis of 10 case projects suggests that the experimental spaces offer joys of finding and interpreting metaphorical forms and meanings caused by the four characteristic categories above. Also, they artificially show the boundaries between reality and virtual spaces in 2-dimensional or 3-dimensional spaces, and form hyper-boundaries, new experience, and an internal mechanism that is vague and chaotic. Therefore, this research concludes that anamorphosis which is a distorted perspective, is not only a simple measure to overcome perspectival errors, but is an existence suitable to the current era, that will extend its potential and value in spatial design.

The objective of commercial space design is not only to sell goods but also provide customer experience so called 'Experience marketing'. Therefore, companies are in search for various methods to give special customer experience and interior design is being considered as an important tool. For example, providing catharsis through commercial interior design, or bringing In the concept of hands-on exhibition into sales area relate to affirmative images of specific products or brands. Graphics in various methods has now become important interior design medium of expression. Therefore the study investigates graphical methods that appear in interior space such as objet, frame, optical illusion, moire and information transmission. It also analyzes their applications and roles in commercial spaces as major element in establishing spatial identity.

Using GPS carrier phase whose cycle ambiguities are resolved, it is possible to perform precise survey requiring centimeter-level positioning accuracy. Because of an optical illusion, we cannot recognize the exact slope of Dokaebi Road. In this paper, we performed kinematic survey experiments in order to calculate the exact slope of Dokaebi Road with high positioning accuracy of CDGPS. By post-processing experimental data using CDGPS, it was possible to generate the exact vertical trajectory of Dokaebi Road with centimeter-level accuracy.

This study is to analyze the works introduced in the collections of Paco Rabanne in an aim to identify formative aesthetic and design concepts. As the data to study the creative concepts and expressions of the designer, fashion photographs were gathered in a focus on collections. Paco Rabanne's fashion philosophy is to shine women who has passion, energy and self-confidence, with glittering materials. For he had a career of fashion accessary designer and architect, he tried to make his work constructively with non-sewing technology. So, his works could be divided three parts of materials which he has made creative fashion with. They are metallic, non-metallic and fabric. In metallic, design concepts are cosmos, egypt, the middle ages, modern technology. And from these the formative aesthetic were mainly characterized by the futurism, cubism and eroticism. In non-metallic, building, purism of primitiveness, nature. And from these the formative aesthetic were mainly characterized by surrealism, primitivism, romantism. In fabric, design concepts are natural phenomena, optical illusion. And from these the formative aesthetic were mainly characterized by cubism, optical art.

In the modern society, already a popular and public part of fashion, hair coloring has the effect of optical illusion on image. This study therefor aims to reveal the effects of varied and fashionable hair coloring on the body images. This is a combination of an actual examination and an experimental study. In order to know the effects of hair colors on body image, 230 female collegians residing in Busan were given a questionnaire on the reality of hair dyeing. Based on the actual research, one subject was selected and stimuli were manufactured. The analysis and examination of the effects of hair dyeing have produced the following conclusions. (1) As a result of dispersion analysis about the image effect according to hair colors, a meaningful difference is recognized in the item and indicates that hair color variation influences the image effect. (2) As a result, extracting the factors that hair colors can influence the image, 3 factors were extracted. The first factor is an intellectual image, the second factor is an active image, and the third factor is a comfortable image. (3) Image effect in hair colors are as same next. Red and Orange color clearly indicate the image of 'charismatic', 'lively', 'positive', 'active', 'light' and 'gorgeous'. Blue and Green color indicates the image of 'unfriendly', 'hard', 'cold' and 'uneasy'. White color indicates the image of 'unfriendly', 'charismatic', 'gorgeous' and 'impure' then Black color has images of 'friendly', 'intellectual', 'indignified' and 'pure'. In other words, the result indicates rather a different tendency comparison with the general color image.

This study views the shadows cast by the light and a subject provides new interpretations rather than it simply being an additive product. Particularly in fashion photograph, light and shadows are often used as tools to convey meaning. Accordingly, this study aims to classify the utilization of the shadow created by light and deriving its expressive characteristics in fashion photograph. To achieve these research aims, literature and case studies were conducted. The results are as follows. First, the shadows were mainly focused on a subject. Secondly, shadows caused by lighting is casted directly into the inside of the main subject in a frame takes a role of omission or emphasis. Third, shadows caused by a second unseen object outside the frame are utilized with the main subject in the frame. Based on these results above, spatial third dimensionality, optical illusion and accentuation were derived as expressive characteristics of the shadow in fashion photograph. As such, in fashion photograph, shadow is an important element for photographers. The variability of the shadow makes it possible for creative changes as its amount, angle and direction can be altered by adjusting the light in accordance with the intention of the artist. Therefore, its utilization methods will be diversified hereafter. Accordingly, it is required to recognize that shadow may be recreated as an independent object in fashion photograph.

The analysis in this work is about costumes among the rhythmic gymnasts in competition, which is intended to develop designs about rhythmic gymnastics costume and provide the basic material from the results. In its research method and range, the general information on rhythmic gymnastics was reviewed in literature and the case analysis was followed about costumes of world high rankers in competition during 2012~2015 seasons. Research showed the following results. First, leotard took a shape of skirt-added one-piece type, where a combination with long tight sleeve, round neck line, and stand-up collar had a relatively higher percentage in design. With regard to a bottom line of skirt, an amorphous type was most common that highlights rhythmical beauty without any particular form. This design exposed shoulders and waists on both sides, expressing the feminine beauty. Second, in color used mainly, white appeared most frequently. In its combination, more than three were employed. Third, transparent mesh was applied as basic, where lace and chiffon were used. Abstract pattern took the highest portion in pattern. Particularly, crystal bead or gradation coloring was used to maximize the visually splendid image, giving an effect of optical illusion as if neckless clothing, choker, bracelet, or glove were worn. Fourth, it appeared that the costume for each event was changed in every season, when only music was substituted but the same earlier costume was put on for the different event.

One of the most important factors for a leather quality inspection is its surface condition. So far a leather quality level has been discriminated by human's eye inspection, But, these kinds of method needs a lot of labor time and cause decision mistakes from an optical illusion. It means leather quality inspection is very subjective and there is no consistency. In this study, we present computer vision based a leather quality inspection system using an Artificial intelligence. Suggested system ran give standard spec for a leather quality and take human inspection duty place.
