  • Human motion analysis is an important research subject in human-robot interaction (HRI). However, before analyzing the human motion, silhouette of human body should be extracted from sequential images obtained by CCD camera. The intelligent robot system requires more robust silhouette extraction method because it has internal vibration and low resolution. In this paper, we discuss the hybrid silhouette extraction method for detecting and tracking the human motion. The proposed method is to combine and optimize the temporal and spatial gradient information. Also, we propose some compensation methods so as not to miss silhouette information due to poor images. Finally, we have shown the effectiveness and feasibility of the proposed method through some experiments.

  • The purpose of this study is to investigate the concept and characteristics of 'grotesque,' examine the aesthetic characteristics of grotesque reflected in arts and dress, and modern fashion. The findings are as follows: 1) Grotesque indicates unnatural, unpleasant, and exaggerated that it upsets or shocks person. The characteristics of grotesque include terror, abnormality, unreality, amusement, disgust. 2) The grotesque art represented terror, abnormality, unreality, amusement, disgust by disordered form, nonnatural things, evil world, unorthodox methods, unrealistic image, strange dreamland. 3) The grotesque dress represented terror, abnormality, unreality, amusement, disgust by exaggerated silhouette, exaggerated adornment, excessive decoration, incroyables, using exaggerated silhouette, crinoline silhouette, bustle silhouette, surrealist style, extraordinary materials, glam rock style, unique silhouette, cyber look. 3) Terror was implied in the punk look suits of Junya Watanabe, and exaggerated outers of Viktor & Rolf. Abnormality was shown in the atypical suit of John Galliano, Junya Watanabe's dress decorated with the extreme ruff, Thom Browne's suit of abnormal proportion. Unreality was reflected in the architectural dress of Gareth Pugh, Mermaid dress of Giles, the surreal suit of Jean-Charles de Castelbajac. Amusement was represented in the amusing suit of Gareth Pugh, John Galliano's dress of sexual perversion. Disgust was reflected in the decadent dress of Thierry Mugler, Undercove's suit, and the ensemble of shocking details.

  • Many clustering algorithms have been used in diverse fields. When we need to group given data set into clusters, many clustering algorithms based on similarity or distance measures are considered. Most clustering works have been based on hierarchical and non-hierarchical clustering algorithms. Generally, for the clustering works, researchers have used clustering algorithms case by case from these algorithms. Also they have to determine proper clustering methods subjectively by their prior knowledge. In this paper, to solve the subjective problem of clustering we make empirical comparisons of popular clustering algorithms which are hierarchical and non hierarchical techniques using Silhouette measure. We use silhouette information to evaluate the clustering results such as the number of clusters and cluster variance. We verify our comparison study by experimental results using data sets from UCI machine learning repository. Therefore we are able to use efficient and objective clustering algorithms.

  • This paper discusses a human body extraction method for mobile robot system. The skeleton features are used to analyze human motion and pose estimation. The intelligent robot system requires more robust silhouette extraction method because it has internal vibration and low resolution. The new hybrid silhouette extraction method is proposed to overcome this constrained environment. Finally, the experimental results show the superiority of the Proposed method.

  • In the history of the costume of Western Europe one of the most interesting apects is that the silhouette of women's dress has been continuously evolved. There can be various origins in this changing silhouette but the most important origin is that clothes of any period are the reflection of the architectural political religious and economic background against which they are worn they must also be djusted to the texture and design of the materials produced at the time and of course there is always the basic instinct of sex attraction. The changing line in men's and women's clothes has been demanded by each period but man's great active life did not required the development of exaggerated line which could restrict his movements. Exaggeration in men's clothes has usually been confined to accessories only details could be simplified or abandoned altogether in time of action. However Woman has no great concern in these restrivtions and when an era demanded an exaggerated silhouette she developed it to the utmost limit with out any hesitation plunged herself into whalebone cane and steel for the desired line and then later to adapt herself to a changing world just as without any hesitaion abandoned all these artificial props. In this study first of all the origin of the corset and the evolution of silhouette will be chronologically studied and rearranged on the basis of written materials such as text books theses and catalogs which are related to corset In this section the most important backgrounds-social religious and economic-which caused the chages of silhouette will be scrutinized in a time order. Then the shapes and functions of corsets will be looked into in a more detailed way. In addition the materials and decorations which were preferred to achieve the desired silhouette will be examined. Finally underwear which was and has been worn for cleanness protection the shapes of outer clothes and erotic mood will be studied.

  • The purpose of this study is to provide the basic knowledge for the pattern development of a flared skirt. Two flat pattern (FP) methods, the concentric circle method and the corrected concentric circle method, and a draping were used for pattern making. Using these patterns, skirts were made with lengthwise grain in the centerline. The influence of pattern making method on the silhouette of the flared skirt was evaluated by the hemlines formed at the skirt worn in a dress form. Moreover, the combined influence of pattern making method and cutting direction on the silhouette of the flared skirt was examined with the draping pattern (DP) skirt and a FP skirt with $45^{\circ}$ bias grain in the centerline. The DP skirt had more uniform nodes and formed a stable wave form than the FP skirts throughout the whole hemlines. The number of nodes was reduced with lining in the two FP skirts, whereas the number of nodes was not changed in the DP skirt. The unit wave form of all the skirts by three patterns showed long loop form, and the slope angles of the unit wave form of the two FP skirts were higher than that of the DP skirt. The silhouette of the flared skirt was highly influenced by the shape of the waist circumference line in patterns. The DP skirt with lengthwise grain in the centerline showed good silhouette with uniform nodes and high marking efficiency, compared to the FP skirt with $45^{\circ}$ bias grain in the centerline.

  • This study investigated the formation of silhouette and hemline shape of knit flare skirts according to the properties of knit material through virtual clothing with a 3D virtual clothing system called i-Designer of Technoa, thus building a database of the property data of knit material to reduce the number of sample making steps repeated and implemented several times in the process of clothes making. The results would help to estimate a silhouette in advance, offer assistance to the development of original knit wear, and explore ways to provide basic data for the development of the knit industry of the nation. The investigator made 12 kinds of experimental clothes to the angles(width of skirt: $90^{\circ}$ and $180^{\circ}$), gauge(7G, 12G, and 15G), and grain directions(wale and bias direction) of experimental clothes for virtual clothing. The dynamic characteristics of knit skirt samples according to each gauge were measured with the KES-FB system. Draper shapes were analyzed with the sectional shape data of hemline based on i-Designer. As for the measurements of the sectional shape of hemline and the formation of silhouette, the number of nodes, the average height of node mountains and valleys, and the hemline width right and left and before and after increased at the angle of $180^{\circ}$ than $90^{\circ}$. As gauges multiplied, the number of nodes, and silhouette angle dropping. When considering grain directions, the number of nodes and silhouette index increased in the wale direction at the angle of $90^{\circ}$ with the number of nodes and silhouette angle increasing in the wale direction at the angle of $180^{\circ}$.
