Silhouette is useful in computer graphics for a number of techniques such as non-photorealistic rendering, silhouette clipping, and blueprint generating. Methods for generating silhouette are classified into three categories: image-based, object-based, and hybrid-based. Hybrid-based method is effective in terms of time complexity but spatial coherence problem still remains. In this paper, we proposed a new hybrid-based method which produces 3D data for silhouette and also guarantees no spatial coherence problem. To verify the efficiency of the proposed algorithm, several experiments are conducted for various 3D models from simple to quite complex. Results show that our algorithm generates no gap between any two consecutive silhouette lines when the silhouette model is magnified significantly.

In this paper, we propose the robust features extraction method of human by using the skeleton model and hybrid silhouette model. The proposed feature extraction method is divided by hands, shoulder line and elbow region extraction. We use the peer's color information to find the position of hands and propose the circle detection method to extract the shoulder line and elbow. Finally, we show the effectiveness and feasibility of the proposed method through some experiments.

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.

Human motion analysis is researched as a new method for human-robot interaction (HRI) because it concerns with the key techniques of HRI such as motion tracking and pose recognition. To analysis human motion, extracting features of human body from sequential images plays an important role. After finding the silhouette of human body from the sequential images obtained by CCD color camera, the skeleton model is frequently used in order to represent the human motion. In this paper, using the silhouette of human body, we propose the feature extraction method based on hybrid skeleton for detecting human motion. Finally, we show the effectiveness and feasibility of the proposed method through some experiments.

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.

Today's radical change of environment and technology spreaded high-technology art by cutting across a general idea of art, expressed machine aesthetic in fashion style by influencing materials and production processes of fashion. The purpose of this research is to take another look at the value and the importance of ornaments in terms of fashion design, to overcome the negative aspect of Technology Fashion by designing Retro Technology Fashion that harmonizes reason with sensibilities through floral patterns. The results of this study are as followings. 1. If Retro technology Fashion was analyzed by time and space element that are postmodernism techniques, there are Ethnic Technology Fashion that are based on space and historical Technology Fashion that are based on time. In terms of spare element, there is the hybrid of revival of exotic folklore with Technology fashion. In terms of time element, there is the hybrid of costumes of before 20th Century with Technology Fashion. It means unifying detail or silhouette of costumes of ancient time to modern time wit Technology Fashion. For another time element, the hybrid of retro fashion after 20th Century with Technology Fashion. The retro nostalgia is revived by the floral patterns or silhouette of Hippie fashion unified with Technology Fashion. 2. Based on above research, Retro Technology Fashion with floral pattern on CAD were designed. As the results, for Ethno Fashion that is spatial retro, 'Asian Technology fashion' was designed with bright colors, China collar that are oriental, and vinyl material. For historical Technology fashion that are based on time, 'Space Middle Age' was designed with tight silhouette, party colored pants and plastic material.

The purpose of this study is to identify the distinctive characterics HYBRID, strictly defined, an offspring that is a cross between different species, genera, or, in rare cases, families, More loosely defined, a hybrid can also be a cross between parents of different subspecies or varieties of a species. Hybrid varieties of plants and animals are of economic value because the hybrid is nearly always more vigorous, larger, and more fertile than either of its parents. Plant and animal hybrids may arise spontaneously in nature or may be produced intentionally by man. Forward-looking fashion explores progress. Adjusting to a world that has integrated genetics and its mutations, the new silhouette seems without references, as if born from a spontaneous generation. A slightly bizarre composite, asymmetrical, discreetly technological aesthetic, it draws on the latest technological details. the pursuit of performance and ergonomics, yet also of comfort and amusement that takes into account the body and its articulations, generates strange garments. Inspired by medical protheses. Focos on fabric touches, their weightiness and surface effects obtained with silicone, rubber or wax. in a range that highlights yellows but can also contrast with colder, slightly surgical hues, the hybrid woman doesn't necessarily want to stand out.

In the $21^{st}$ century, technology is a tool for the expansion of the five senses and physical ability that works as an element for posthuman identity. This study analyzes and theorizes on the characteristics of the posthuman body in fashion illustration. The method of this study analyzes documentaries about posthuman and fashion illustration. The results are as follow. Posthuman body types are classed as hybrid body, plastic surgery body, and digital body. The characteristics of the posthuman body are categorized as ultra- functional prosthetic, mythical undifferentiated, radical plastic surgery type and post-physical digitization type. The ultra-functional prosthetic type shows a restored body and upgraded functional body through a machine hybrid, cyborg suit and mannequin hybrid. It is a break from classical gender identity to form a nerve sense extension that displays physical and abstract power. The mythical undifferentiated type shows a therianthropic form, parts of an animal body, radical skin and gender bending. It represents the return to an undifferentiated world, the desire of a powerful being and the possibility of radical transformation. The radical plastic surgery type shows a photomontage of an ideal body, transgendered body, grotesque body marking, absence of partial or overall face organ and the expansion of abnormal body organs. It represents the expression of narcissism, unconscious desire, fantasy, fear and suggests an alternative ideality, sexual attachment and ambiguous gender identity. The post-physical digitization type shows an imperfect form or duplicated ego image through the omission of the body silhouette or detailed form, fragmented image using net, representative self like optical illusion using typography, an imperfect vague silhouette and immaterial body outline through the use of virtual light. It represents the lack of desire, narcissism, fluidity in a virtual space, the continued creation of a new self, ambiguous gender identity and the liberation of environment, sex, and race. Likewise, the posthuman in fashion illustration shows the absence of a species boundary, destruction of classical gender identity, a new personality and virtual self image.
