The purpose of this study was to compare fitting of the upper garment by brassiere cup size and types of bodice block. This study conducted a 3D virtual garment system by applying three types of bodice block (I, II, III) and experimental pattern of the bodice block to 3D avatars of four individuals with the following measurements: under bust circumference of 73.5 cm and bust circumferences of 83.5 cm, 86.0 cm, 88.5 cm, and 91.0cm. The results of the study were as follows. First, for 83.5 cm bust circumference (A Cup), appearance of the three types of bodice block (I, II, III) was appropriate. However, as bust circumference increased in size, shape became inappropriate. The depth and width of the armhole, within 15 cm and 11 cm, respectively, were found to be appropriate. In case of 91.0 cm bust circumference (D Cup), all three bodices (I, II, III) were inappropriate. Second, the results of the draft of the experimental patterns of the bodice block of bust circumference measuring 83.5 cm, 86.0 cm, 88.5 cm, and 91.0 cm in the 3D avatars of the four individuals revealed similarities in the frontal view of the silhouette in the four avatars; in the case of the lateral view of the silhouette, lateral width grew wider as bust circumference of the silhouette became larger, but the shape of armhole showed no changes. The depth of the armhole showed little changes from 15.1 cm to 15.22 cm, and the height of sleeve (armscye depth 13.6 cm within +2 cm) remained similar. The difference in width of the armhole from 11.26 cm to 11.37 cm was rather small. The width of the upper sleeve (8.97 cm) seemed to be appropriate as it remained within the 2-3 cm boundary.

The aim of this study was to use a 3D human body scanner to analyze the cross section of different body parts when a girdle is worn. Two types of girdles were selected as experimental garments: a standard type girdle (Garment A) and a high-waist type girdle (Garment B). Their sizes were 88 (S) and 94 (M). Ten female subjects in their twenties who wear girdles sizes 88 (S) and 94 (M) participated the experiment. Their bodies were scanned three times with the 3D human body scanner, before and after wearing experimental girdles. The data were collected by overlapping the cross sections of the 3D scanned body shape data. The space length was measured from the overlapped cross sections. The results show that human body silhouette are changed after wearing the compression type garments and the amount and place of the body change is different by style of garments. First, the waist girth shape became rounder. Second, there was a definite difference in space amount at abdomen girth between two types of girdle. The abdomen area was pushed toward the front after wearing the standard type girdle (A). The high-waist type girdle (B) pushed abdomen area toward the back. Third, there was clear difference at the hip area after wearing two types of girdle. The hip area pushed toward the front with the standard type girdle (A) and pushed toward the back with the high-waist type girdle (B).

This paper describes an automatic 3D models generation algorithm based on 2D silhouette images, using X-ray camera without camera parameters. The algorithm takes a multi steps process approach. First, a series of 2D silhouette images is captured from different directions of object and then converted to binary images. An octree data structure is constructed for voxel-based representation of object. An estimate 3D volume of object can be reconstructed by intersecting voxels and the 2D silhouettes. The marching cube algorithm is applied to get triangle mesh representing of the obtained 3D model for rendering.

This study aims to provide the basic reference necessary in improving the fitness of a ready-to-wear brand jacket through a research on the wearing conditions and preferences regarding a tailored jacket by body shape of the women in their 30s. The following results were drawn by implementing the research method of the self-administered type survey targeting 201 women in their 30s from August 14~28, 2014. First, the female consumers in their 30s preferred one button slim fit jacket when purchasing a tailored jacket and chose a close-fitting size. Second, the slim fit tailored jacket consumers preferred a jacket with some extra portion in the bust and hip areas but tightly fit in the waist area. Third, when purchasing a jacket under the ready-to-wear size system, the women with a triangle shape similar to a standard body silhouette had less instances of mending a jacket while the women with a big or small rectangle shape different from a standard body silhouette had more experiences of mending a jacket. Accordingly, it is expected of the manufacturers to increase the fitness satisfaction of the consumers by identifying the problems concerning the fitness and suggesting the improvement plans to produce a jacket of a good fitness reflecting the properties of different body shapes through such research on the wearing conditions and preferences regarding a tailored jacket by body shape of the women in their 30s.

손 모양 인식은 자연스러운 인간-컴퓨터 상호작용을 위한 기반 기술이다. 본 논문에서는 Kinect 기반 손 모양 인식을 위해 효과적으로 손 영역을 검출하기 위한 방법에 대해 논의한다. Kinect는 컬러 영상과 적외선 영상(혹은 깊이 영상)을 동시에 획득할 수 있는 카메라이기 때문에, 손 영역을 검출하는 과정에서 컬러 정보와 깊이 정보를 활용할 수 있다. 즉, 손 영역은 스킨 컬러를 가지는 영역으로 검출될 수도 있으며, 일정한 깊이 값을 가지는 영역으로 검출될 수도 있다. 그러므로, 이러한 방법들의 성능을 분석하여, 손 영역의 실루엣이 깔끔하게 도출될 수 있도록 적절히 결합하는 방법이 마련되어야 한다. 이는 손 모양 인식률을 크게 좌우하기 때문이다. 최종적으로 일반적인 환경에서 손 영역 검출 방법의 차이에 따른 손 모양 인식률을 비교함으로써, 성능이 우수한 손 영역 검출 방법을 제안한다.

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.

The purpose of this study is to suggest standard bodytype which offers criterion for the sizes and shapes to interpret various bodytypes, to estimate fitting, and to construct ready-made clothing. There were two ways of analyzing bodytypes of subjects from the viewpoint of statistic and beauty. We had carried on the analysis from the viewpoint of statistic in the Part(1) and we carried on the analysis from the viewpoint of beauty in this Part(2). Taken as a sample, the subjects were ninety-seven females who were between the aloes of 18 and 24 rears o1d. They were measured on November 1999. The data of seven hundred and four females,18∼24 year-old, from the National Somatometry Survey of 1997 were used for analysis, too. The first analysis from the viewpoint of beauty was executed to the front and side photographs of the subjects to analyze the general traits of the beautiful bodytype. The second analysis from the viewpoint of beauty was executed to subjects who were in both High-frequency proportion range and Beautiful bodytype group. As the result, four groups in Beautiful and High-frequency proportion range were selected. The standard proportion was analyzed with the size and shape of four groups. Based on the standard proportion, the size, shape and silhouette of the standard bodytype were analyzed. To verify the size, shape and silhouette of the standard bodytype, the location of the standard bodytype in the 1997 National Somatometry Survey group was analyzed. As the result, the standard bodytype was verified as proper criterion to interpret various bodytypes, to estimate fitting, and to construct ready-made clothing.
