  • This thesis presents a method for 3D modeling of facial expression from frontal and mirror-reflected multi-image. Since the proposed system uses only one camera, two mirrors, and simple mirror's property, it is robust, accurate and inexpensive. In addition, we can avoid the problem of synchronization between data among different cameras. Mirrors located near one's cheeks can reflect the side views of markers on one's face. To optimize our system, we must select feature points of face intimately associated with human's emotions. Therefore we refer to the FDP (Facial Definition Parameters) and FAP (Facial Animation Parameters) defined by MPEG-4 SNHC (Synlhetic/Natural Hybrid Coding). We put colorful dot markers on selected feature points of face to detect movement of facial deformation when subject makes variety expressions. Before computing the 3D coordinates of extracted facial feature points, we properly grouped these points according to relative part. This makes our matching process automatically. We experiment on about twenty koreans the subject of our experiment in their late twenties and early thirties. Finally, we verify the performance of the proposed method tv simulating an animation of 3D facial expression.

  • The purpose of this study is enrich the expressivity in fashion illustrations by looking into the expression of humor which is seen in the fashion illustration. In addition, this study is expected to provide a theoretical basis to the people whose works are concern with Fashion design. It is the fashion illustration that expresses the specific concept that accords with the purpose of drawing. And we need to create our own techniques freely and to develop them into higher ones. In this view, we can say that the humor in the fashion illustrations shows us the new world of expression. And we can also say that it fills the roles of social functions to purify human emotions with helping the communication between people in our highly developed society. Finally, the expression of humor in fashion illustrations can be described as followings. First, they are relate with the superiority, disparity, psychic release in the theory of humor's origin. Second, the image of humor can be induced by changing the figure of human body. Third, it can be encouraged by contrasting the different fashion images. Forth, we can use well-known icons that cause the humor does not only give us laugh but also reflect the era, society enlarge the range of expression in fashion illustrations.

  • The purpose of this treatise is to study external form and internal meaning of minimal expression fashion which appeared as a major stream in modern fashion trends to understand one aspect of modernism in fashion and also to gain insight into internal value of human beings through fashion. The results can be summarized as follows : Firstly , minimalism is a trend in art attempting to seek essence of the object by presenting simple and disciplined expressions by minimal formative means and minimal production process. Secondly, minimal expression in fashion means seeking simplicity an dpurity by using minimum design elements and minimal productive process. Thirdly, external from of minimal expression fashion can be created through application of following minimal expression techniques. 1. Minimal expression techniques in terms of line mean smooth curve flowing along body contours, straight lines of diagonal lines into desciplined silhouette or rendering internal contour lines. 2. Minimum expression techniques in terms of forms mean forms of smooth curves flowing along boyd or forms with simple geometric forms from qualitative aspects, In terms of volume it means quest for essence of pure body itself by revealing body as it is by minimizing the size of dress or its area and herein is contained using simple geometric pattern or utilizing textiles without any patterns.3. Minimal expression techniques by colors mean simple colors such as primary colors, colors without clear distinctions or natural colors and in terms of quantity it means quest for one color within one item of dress or combination of each items when getting dressed. 4. Minimal expression techniques in terms of fabrics mean fabrics with simple surfaced. In terms of quantity it means quest for essence of tight fitting thin textiles to human body or using transparent materials to human body thus exposing body contours as it is. 5. Minimal expression techniques in terms of productive process mean minimizing process of tailoring , sewing or ornamenting and seeking for simplicity and purity. 6. Minimal expression techniques in terms of manufacturing process mean selection of technique conveying simple image with disciplined simple image. Fourthly, minimal expression fashion with external expression as mentioned in the above lay body-priority style and its internal meaning can be asummed as quest for essence and purity of human body.

  • Understanding of human emotion has a high importance in interaction between human and machine communications systems. The most expressive and valuable way to extract and recognize the human's emotion is by facial expression analysis. This paper presents and implements an automatic extraction and recognition scheme of facial expression and emotion through still image. This method has three main steps to recognize the facial emotion: (1) Detection of facial areas with skin-color method and feature maps, (2) Creation of the Bezier curve on eyemap and mouthmap, and (3) Classification and distinguish the emotion of characteristic with Hausdorff distance. To estimate the performance of the implemented system, we evaluate a success-ratio with emotional face image database, which is commonly used in the field of facial analysis. The experimental result shows average 76.1% of success to classify and distinguish the facial expression and emotion.

  • This study analyzed the characteristics of spatial expression in the Barcelona Pavilion to be based on tectonics. Mies pointed out the image of materiality about the material rather than the process of tectonics using the material, and he also expressed demateriality in the image of each material through the reflection. To be liberated from structural matters, the wall has been introduced. He intended to show the design plan as the independent structural system, however, the wall actually seems to be supporting the roof that shows rather clearly self-contradictory because of the expression of materiality in the material. In terms of architectural elements; wall, roof, column, floor, and so forth, tectonic expression and abstract aesthetics stands face to face, because of hiding the productional process and transforming to line and surface in the image of materiality. The interior of the glass wall seems fairly closed space from the exterior, because materiality and reflection of materials of columns and podium. The character of experiential space is inconsistent and fragmentary because of the splendid images from maternality and reflection on the wall, and collision with the reality and the image the wall reflects, even though the geometrical space of the Pavilion's plan has the mutual penetrability and organic character.

  • 본 논문에서는 Local Binary Pattern 히스토그램의 템플릿 매칭을 이용한 얼굴 표정 인식에서 인식률을 높이는 방법을 제안한다. 이 방법에서, 주어진 얼굴 영상은 작은 크기의 블록으로 분할되고 각 블록에서 구해진 LBP 히스토그램은 블록 특징으로 사용된다. 입력 영상에서의 블록 특징과 모델의 해당블록 특징 사이에서 블록 상이도가 계산된다. 주어진 영상과 모델 영상 사이의 영상 상이도는 블록 상이도의 가중 합으로 계산된다. 기존의 방법들에서는 직관에 따른 블록 가중치를 사용하는데 본 논문에서는 블록 가중치를 트레이닝 샘플들로부터 최적화를 통해서 구하는 방법을 제안하고 있다. 실험을 통해서 제안된 방법이 기존의 방법보다 우수함을 보인다.

  • The purpose of this study were 1) to find out the structural elements in classifying clothes images, and 2) to segment the consumer market for women's street clothes based on clothes image preferences and to identify the group differences in psychological variables, purchasing behavior variables and demographic variables. The sample was taken from 1106 middle class women who were in thier 30's∼40's living in Gwangju city. Consumers were classified into six groups: active image group (35.4%), feminine image group (25.9%). daring image group (16.5%), elegant image group (10.8%), dressy image group (8.9%) and brisk image group (3.5%). Women in their 30's∼40's preferred elegant image, daring image, active image and feminine image. Elegant image oriented group: This group is the lowest education level group and has the highest rating of housewife. This group has the lowest scores use of person information search, Daring image oriented group: Woman in their 30's prefers daring image. This group thinks practical benefit sought is less important than self-expression benefit sought. This group has the highest scores use of non-person information search, Active image oriented group: This group is practical benefit seeking group. and purchases the lowest amount of clothes. The amount of average household income is the lowest. Feminine image oriented group: The amount of average household income is the highest. This group perceives more youth$.$fashion benefit sought and self-expression benefit sought than elegant image oriented group. ANOVA, $\chi$$^2$-test revealed differences among groups according to benefit sought use of information sources, purchasing behavior variables and demographic variables.
