This paper presents a new approach to non-parametric modeling of cutter swept surface (CSS) for cutting simulation. Instead of explicitly modeling cutter swept volumes, silhouette curves of the cutter surface are utilized in computing the z-value of the CSS at a grid point on the x,y-plane. The non-parametric evaluation of the CSS constitutes the integral part of 3-axis cutting simulation. The proposed method is more efficient than the existing ones in the case of conventional cutters (i.e., ball-end mills and flat-end mills), and more importantly, it enables the non-parametric modeling of the CSS for the round-end mills which was not possible with the existing methods.

In the result of classification body types for 100 adult women by direct measurements and antropometric measurements, the mean of weight is bigger than he mean of weight of 97'. So modern 20's women is more than than 94'. In the result of factor analysis, 5 factors were extracted (horizontal sizes, vertical sizes, and degree of shoulder) from exponent sizes of the antropometric measurements item, and another 5 factors were extracted (thick of body, horizontal form of the torso, silhouette of the torso, and size of abdomen) from direct measurements item. The body types are classified into 4 types by cluster analysis in the result of direct measurement item, and another body types are classified into 5 types by antropometric measurement item, it was classified into the horizontal size and the shape and silhouette of torso, and by direct measurement item, it was only classified into the vertical and horizontal size. So for the patternmaking of clothing, it is more adoptable the classification of body by antropometric measurement item than direct measurement item.

We present a legorization framework that produces a LEGO model from user-specified 3D mesh model. Our framework is composed of two stages: voxelization and legorization. In the voxelization, input 3D mesh is converted to a voxel model. To preserve the shape of the 3D mesh, we devise a silhouette fitting process for the initial voxel model. For legorization, we propose three objectives: stability, aesthetics and efficiency. These objectives are expressed in a tiling equation, which builds a LEGO model using layer-by-layer approach. We legorize five models including characters and buildings to prove the excellence of our framework.

This study is on the esthetic characteristics in the haute couture work of Chanel. It first reviews the lives and the fashion philosophy of Chanel, a senior designer and Lagerfeld as representatives of the maison, from the haute couture collection since 2000. The results of the study are the following. First, reinterpreting the tradition, Chanel reproduced historical dress items or silhouette with modern sense, or she created a new modern Chanel image through her original restructuring and dismantling. Second, Chanel expressed balanced beauty of compounded eclecticism by accord between simplicity and ornamentation, which meant her design showed impartial beauty with simple silhouette, decoration with colors, accessories, and ornaments. Third, Chanel did not divide the value between men and women, and instead expressed androgyny through dismantling each gender's characteristics by borrowing or mixing. As a result, she emphasized the female image or created a new style through expressing symbolic image embracing masculinity.

This paper discusses a skeleton feature extraction method for ubiquitous robot system. The skeleton features are used to analyze human motion and pose estimation. In different conventional feature extraction environment, the ubiquitous robot system requires more robust feature extraction method because it has internal vibration and low image quality. The new hybrid silhouette extraction method and adaptive skeleton model are proposed to overcome this constrained environment. The skin color is used to extract more sophisticated feature points. Finally, the experimental results show the superiority of the proposed method.

This paper proposes the robust matching algorithm of the optical images. To do this, we propose two algorithms, that is, matching algorithms when the silhouette of images is detected and when it is not detected. Also, we propose the method for detecting the matching template and non-matching template from each optical image. And then, optical images are matched according to the coefficient of correlation represented by the similar degree between optical images. Finally, we show the effectiveness and feasibility of the proposed method through some experiments.

본 논문에서는 은닉 마르코프 모델을 바탕으로 하는 발걸음을 이용한 개인 식별 시스템을 제안한다. 개인의 발걸음은 연속적인 자세나 움직임의 집합으로 나타낼 수 있는데, 구조적으로 연속적인 움직임의 변화는 확률적인 특성을 가지고 있기 때문에 은닉 마르코프 모델을 이용하여 적절하게 모델링 할 수 있다. 개인의 발걸음은 N개의 이산적인 자세 간의 전이로 이루어졌다고 가정하였으며, 이를 계산하기 위해 MMSI라는 발걸음 특징 모델을 제안하였다. MMSI는 발걸음 인식에 중요한 역할을 하는 시공간적인 정보를 가지고 있는 그레이-스케일 영상이다. 실험 결과는 MMSI를 이용하여 은닉 마르코프 모델을 바탕으로 한 발걸음 인식 결과를 보여준다.

This paper presents a novel system that analyzes and recognizes a gait based on shape context on silhouette images. The main functions of the system consist of three steps: First, the system extracts the silhouette images from galt image sequence by performing a simple pre-processing and acquires the AGM(Averaged Gait Map) by averaging them. Next. it computes the cross-correlation between the AGMs. Finally, it classifies the AGMs based on the cross-correlation using nearest neighborhood classification. The proposed system uses two cues to classify a gait: One corresponds to biometric shape cue such as body height width. and body-part proportions. The other corresponds to gait cue such as stride length and amount of arm swing. Perceptionally, the biometric cues are sailent on the double support (both legs spread and touching the ground) while the gait cues on the midstance. Through a variety of experiments, it is proved that the property of a gait is mainly influenced by gait cues than biometric cues.

Much western philosophical thinking is constrained by ocularcentrism. Hence, multi-sensory experiences hold the most prominent position in contemporary art, and visual tactility, where feelings of touch through sight, become a powerful medium of expression in fashion. This study analyzes visual tactility in Alexander McQueen's design, where design elements are in focus. This investigation aims to bring the concept of visual tactility in fashion, and by doing so, enhance valuable aesthetic possibility. The result of the study is as follows: First, Creative silhouette is something that is constructed by his impeccable cutting and tailoring skills. In fabrics, he often suggests unconventional materials by uncompromising approach to fashion. Color contrasts refer to color sensibility, which reminds of grotesque image. McQueen's aggressive aesthetic awareness results in visual tactility in fashion.
