We propose an efficient framework to realistically render 3D faces with a reduced set of points. First, a robust active appearance model is presented to detect facial features in the projected faces under different illumination conditions. Then, an adaptive simplification of 3D faces is proposed to reduce the number of points, yet preserve the detected facial features. Finally, the point model is rendered directly, without such additional processing as parameterization of skin texture. This fully automatic framework is very effective in rendering massive facial data on mobile devices.

This research studies socio-cultural hegemony change focused on male society through contemporary ideal masculine images of Asian men (especially Korean and Chinese men). Participants were: South Korean men in and around Seoul and Chinese men in Beijing and Shanghai. The youngest survey participants in their 20's and the oldest in their 40's were asked about their present men's appearance images and masculinity as well as asked to evaluate satisfaction with their own style, and interest in fashion trends on a 5-point Likert scale. In this research, an ideal masculinity was tested by 6 characters (traditional masculinity, macho masculinity, androgynous masculinity, adolescent masculinity, trendy masculinity, and general masculinity) as male avatars. Asian men's consciousness of an ideal masculinity image has moved gradually from traditional masculinity to trendy masculinity, leading to new roles in a socio-cultural agenda. Korean and Chinese men are more interested in appearance and notice fashionable styles to be trendy that follow the latest fashion because most other Asian men reflect a traditional masculinity as an ideal appearance image.

The purpose of this study was to classify individualism-collectivism orientation into groups and analyze the difference of fashion leadership and expected values of appearance management by the groups. Questionnaires were administered to 376 adults in 20's and 30's living in Deagu and Kyungbook area through June 10~June 20, 2013. Frequency, factor analysis, reliability analysis, cluster analysis, correlation analysis, ANOVA, Duncan-test, t-test, and $X^2$-test were used for data analysis. Survey method was used to collect data for this study and the measures such as individualism-collectivism orientation, fashion leadership and expected values of appearance management consisted of 5-point Likerties scale. Individualism-collectivism orientation was categorized into collectivism, competition consciousness, love of family, and individual focus. Fashion leadership were found as opinion leadership, double leader, and innovator. Expected values of appearance management were found as pleasure/individuality, other consciousness, and conformity. This indicates that women showed high opinion leader, double leader, and innovator of fashion leadership and pleasure/individuality, and conformity of expected values of appearance management while men care more about competition consciousness, love of family, and individuality focus of individualism-collectivism orientation. Individualism-collectivism orientation showed significant correlation with the sub-variable of fashion leadership and expected values of appearance management. Individualism-collectivism orientation were classified into three groups such as competition collectivism, individuality, and low individual-collectivism. A test of significance in groups was determined by demographic variables like gender, age, occupancy and monthly income. Groups showed significant difference in fashion leadership and expected values of appearance management.

Mobile robots are used in modern life; however, object recognition is still insufficient to realize robot navigation in crowded environments. Mobile robots must rapidly and accurately recognize the movements and shapes of pedestrians to navigate safely in pedestrian-rich spaces. This study proposes real-time, accurate, three-dimensional (3D) multi-pedestrian detection and tracking using a 3D light detection and ranging (LiDAR) point cloud in crowded environments. The pedestrian detection quickly segments a sparse 3D point cloud into individual pedestrians using a lightweight convolutional autoencoder and connected-component algorithm. The multi-pedestrian tracking identifies the same pedestrians considering motion and appearance cues in continuing frames. In addition, it estimates pedestrians' dynamic movements with various patterns by adaptively mixing heterogeneous motion models. We evaluate the computational speed and accuracy of each module using the KITTI dataset. We demonstrate that our integrated system, which rapidly and accurately recognizes pedestrian movement and appearance using a sparse 3D LiDAR, is applicable for robot navigation in crowded spaces.

This research aimed for 20 latter man whose body shape of torso alters remarkably to develop nipper pattern of running type considered characteristic of body shape of 20 latter man to keep rather balanced body shape against middle age when body shape changes extremely. 1. running type nipper pattern design. Pattern of running, lining and nipper were designed by flattening surface shell. A basis line of running pattern is completed by applying reduction ratio after 3 times of modification & complement based on surface shell. Nipper pattern is designed with design line set by a plaster cast based on running pattern line. Lining pattern is designed with lining design line set by a plaster cast based on running type outside material and nipper pattern. 2. Functional evaluation of research and commercial nipper. Functional inspection through dress test was applied 5point evaluation method and the result of functional inspection on the sight of a wearer is that research nipper(running reduction ratio 15%, nipper reduction ratio 18%) averaged more 4.8point but commercial nipper averaged less 1.8point in the aspect of 20 items such as wear sensibility, motional function and external appearance aesthetic. Research running type nipper scored high in order of motional function, looks of side, back, front and whole and wear sensibility. Functional inspection in the point of view of an observer is that research nipper(running reduction ratio 15%, nipper reduction ratio 18%) averaged over 4.8point and commercial nipper averaged under 1.9point in 17 items of external appearance beauty. Research running type nipper marked high in order of looks of back, whole, front and side.

This study evaluates the performance of image to patient registration algorithm by using stereo vision and CT image for facial region surgical navigation. For the process of image to patient registration, feature extraction and 3D coordinate calculation are conducted, and then 3D CT image to 3D coordinate registration is conducted. Of the five combinations that can be generated by using three facial feature extraction methods and three registration methods on stereo vision image, this study evaluates the one with the highest registration accuracy. In addition, image to patient registration accuracy was compared by changing the facial rotation angle. As a result of the experiment, it turned out that when the facial rotation angle is within 20 degrees, registration using Active Appearance Model and Pseudo Inverse Matching has the highest accuracy, and when the facial rotation angle is over 20 degrees, registration using Speeded Up Robust Features and Iterative Closest Point has the highest accuracy. These results indicate that, Active Appearance Model and Pseudo Inverse Matching methods should be used in order to reduce registration error when the facial rotation angle is within 20 degrees, and Speeded Up Robust Features and Iterative Closest Point methods should be used when the facial rotation angle is over 20 degrees.

The research was done against female workers in public officers to find out the actual conditions and usage of uniforms worn in government and other public offices, to find out the degree of their satisfaction for it's appearance, costs, functions and representation. The research was done by questioning 402 female workers about their uniforms in various government and other public offices and the results analysed from the research are as it follows below. 1. The shape of uniforms in public offices were mostly in three piece(jacket+vest+skirt) shape, many of them in gray color and the material were made of blended fabrics. 2. The satisfactory garde of the uniform couldn't even reach the level of '3 point', in which it is easy to tell that the workers had low satisfaction with their uniforms. The level of satisfaction in it's appearance, functions, costs and representation were below average, the rankings starting with functions, representation, appearance, costs and it was shown that the most satisfied category was in it's functions and the lest in costs.

3차원 물체는 카메라의 시선 방향에 따라 다른 영상을 생성하므로 2차원 영상만으로 3차원 물체를 인식하는 것은 쉬운 일이 아니다. 특히 영상생성 시 강한 perspective transformation 이 발생할 경우 2차원 국소 특징을 이용하는 SIFT(Scale-Invariant Feature Transform) 알고리즘은 매칭에 활용하기 어렵다. 본 논문에서는 3차원 물체를 하나의 특정 축 중심으로 회전시키면서 얻은 복수의 영상을 학습 데이터로 활용하여 SIFT 알고리즘을 개선한 물체인식 방법을 제안한다. 이 방법은 복수 영상의 특징점들을 하나의 특징 공간으로 합성하고 그 특징점들 간의 기하학적인 제약조건을 확인하여 3차원 물체를 인식하는 방법이다. 실험에서는 알고리즘의 유용성을 먼저 확인하기 위해 조명조건과 카메라의 위치를 일정하게 유지하였다. 이 방법에 의해 SIFT 알고리즘만으로 인식이 힘들었던 3차원 물체의 다양한 외관(appearance) 인식이 가능하게 되었다.

The purpose of this study is to quantitatively analyze the impacts of the distribution of easing contraction of the sleeve on the external appearance of bodice and sleeve through virtual clothing simulation. Virtual clothing is conducted by differentiating the sleeve easing in accordance with the experimental condition of bodice and sleeve that are followed by draping. And then the evaluation is carried out. As a result of an analysis of the similarity between the virtual garment and the actual clothing, the whole external appearance of the bodice and sleeve was expressed similarly. The external appearance according to the distribution of easing contraction got better as the easing contraction of sleeve was concentrated on sleeve cap in front while the appearance was better at the back as it was more gently distributed than in the front. In a comparison of armhole form, the clothing of which the top of it was most similar to S0 was S4 in which the gap between the armhole and the arm was the least and the front and rear silhouette fell relatively well. In a comparison between the position of bust circumference line and that of the sleeve base line, the front of the sleeve matched the bust circumference line as the easing contraction was distributed close to the center of the sleeve cap while in the back, the sleeve base line and the bust circumference line matched when some easing contraction ratio was added close to the armpit point. The cross section figures of garment space of the shoulder, the margin was evenly distributed in S4 or S5 with differing distributions of easing contraction in the front and the back. This study is significant in that it supplies the objective baseline data which makes a novice more able to make a good external appearance of the sleeve.

The purpose of this study is to analyze the acceptance and interpretation of pop musician's image in the Korean youth subculture, Fan Costume play(Fancos). Fancos subculture took the most active attitude to accepts of the pop musician's image and therefore was assumed to have various and differential acceptance aspects. The ethnographic method was used in order to approach more closely from their point of view. The cultural activity of Fancos subculture was imitation and reappearance of pop musician's appearance. Actually Fancos is a kind of fan-culture which idolized Korean pop music star. The acceptance of musician's appearance in Fancos is found out in two aspects. One is passive acceptance aspects that inforces conformity of star fashion and follows servilely ideal body image which promoted by cultural industry. The other is unique acceptance aspects that Fancos members interpret the musician's image in their own way. Those members experience pleasure through their own meaning. And homology of their appearance makes a distinction between of themselves from other youth and intensifies their group identity. As above analyzed, Fancos subculture has differential acceptance of pop music star's image comparing to other youth and even their stylistic appearance reflects not only their fandom but also their own meaning. Consequently, pop musician's image as a popular cultural text is accepted not equal to all populace but dissimilar along with contexts and trails of the acceptance group.
