The purpose of this study is to present the method to select optimal size for the industrial products which are closely related to human's body size. For this purpose, human factors such as body characteristics, body features, and preference in product selection which needs to be considered in setting standards were analyzed. This analysis is to select optimal size to minimize losses caused by the difference of size between demand by the customers and supply from the manufacturers. Using loss function, repetitive calculation process algorithm by using bisearch method was applied in selecting the sizes of demand and supply which minimize the total expected losses. For cumulative normal distribution probability, IMSL routine DNORDF was used. In case study, comparison has been made between the result which was calculated using presented algorithm and the results calculated by the process currently used by KS and ISO by measuring aged women's body size in human factors side and sorting them through the factor analysis and cluster analysis for feature factor extraction. Thus, they can be used as a basis for establishing industrial product standards.

본 논문에서는 배경의 움직임이 유발되는 능동 CCD 카메라를 통하여 실시간으로 포착되는 영상 데이터를 대상으로 카메라의 사전 설치 정보나 좌표 보정(calibration) 없이 강체(rigid body) 혹은 비 강체(non-rigid body)의 움직이는 물체를 추출하고 이의 이동 방향을 판단하여, 추적하는 효율적인 알고리즘을 제안한다. 이동 물체의 영역분할을 위하여 동체의 형태를 규정하는 특징 점을 추출하고, 시간에 따른 특징 점의 이동 벡터로 구성된 특정 플로우 필드(feature flow field)를 구한 후 이들을 다차원 특정 공간상에서 군집화(clustering)함으로써 동체를 추출한다. 제안하는 IRMAS(lncremenatal Rotational Minimum Angle Search)에 의하여 군집화된 특정점들의 볼록 다각형(convex hull)올 구함으로써 이동 물체의 개괄적인 외곽 형태를 재 구성한다. 또한, 이동 궤적의 갑작스러운 변화를 가져올 수 있는 동작 특성을 가지는 이동 물체의 효과적인 추적을 목적으로 개선된 선형 예측기를 사용하였다. 이동 궤적 예측기는 기존의 선형 예측기의 차수를 이동의 변화도에 따라 적응적으로 조정함으로써 예측 오차를 감소시켜, 빠른 속도로 이동 궤적에 수렴한다.

In clinical practice, CT Angiography is a powerful technique for the visualziation of blood flow in arterial vessels throughout the body. However CT Angiography images of blood vessels anywhere in the body may be fuzzy if the patient moves during the exam. In this paper, we propose a novel technique for removing global motion artifacts in the 3D space. The proposed methods are based on the two key ideas as follows. First, the method involves the extraction of a set of feature points by using a 3D edge detection technique based on image gradient of the mask volume where enhanced vessels cannot be expected to appear, Second, the corresponding set of feature points in the contrast volume are determined by correlation-based registration. The proposed method has been successfully applied to pre- and post-contrast CTA brain dataset. Since the registration for motion correction estimates correlation between feature points extracted from skull area in mask and contrast volume, it offers an accelerated technique to accurately visualize blood vessels of the brain.

This study is the primary basic study about the spatial feature of modeling of Fashion Design. Then, this researcher lays significance in establishing the basic system about the character of dress and its ornaments as modeling in spatial-formal, dimension, examining the feature of modeling closely through perception principle and offering the basic principle to plan and organize the modeling space for dress and its ornaments on the basis of it. To generalize the findings is as follows : First, the spatial system of modeling for dress and its ornaments is made with 3 elements such as space, human beings and dress and its ornaments. Second, the form of dress and its ornaments and the spatial organization start from the structural basis which is human body, and the sensible system of body is made through inter-action, but the aesthetic expression is complet-ed by the moment of body. Third, the characteristic principle of model-ing for dress and its ornaments which was suggested in Chapter IV is based on the visuo-per-ceptional modeling experience, and these thinking contents are inputted in cognition course as the invisible in formation in the new space plan and organization and activate the apperception course and aim at the action about aesthetic judgement.

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.
