Purpose: This study was done to compare of adult body composition and body image before and after regular exercise program at a sports center. Method: The participants were 32 adults who were beginning regular exercise at a sports center in D city. The body composition was measured by body weight, soft lean mass, fat mass, percent body fat, fat distribution, degree of obesity and BMI, using the Inbody 3.0. Body image. Data were collected using structured questionnaires and analyzed using paired t-test. Results: 1. Significant improvement was shown in body composition. 2. The score for body image increased after the program, but the change was not statistically significant. Conclusion: The short-term exercise program was very effective in improving body composition, but changes in the evaluation of body image need long-term exercise. Also, we were concluded that it is very important to consider preference level when evaluating body composition and body image.

This paper proposes an automatic object segmentation and background composition method for video communication over consumer mobile phones. The object regions were extracted based on the motion and color variance of the first two frames. To combine the motion and variance information, the Euclidean distance between the motion boundary pixel and the neighboring color variance edge pixels was calculated, and the nearest edge pixel was labeled to the object boundary. The labeling results were refined using the morphology for a more accurate and natural-looking boundary. The grow-cut segmentation algorithm begins in the expanded label map, where the inner and outer boundary belongs to the foreground and background, respectively. The segmented object region and a new background image stored a priori in the mobile phone was then composed. In the background composition process, the background motion was measured using the optical-flow, and the final result was synthesized by accurately locating the object region according to the motion information. This study can be considered an extended, improved version of the existing background composition algorithm by considering motion information in a video. The proposed segmentation algorithm reduces the computational complexity significantly by choosing the minimum resolution at each segmentation step. The experimental results showed that the proposed algorithm can generate a fast, accurate and natural-looking background composition.

Through the formative analysis of the traditional jokakbo, we have composed surface composition that was made by a perfect square, triangle, a weather vane type, vertical type, cintamani type, and a mixed rectangular. And we have composed 18 kinds of motif stimulants that was made by vivid tone, pale tone, and so on, and finally analyzed sensibility image, preference rate of them. The cause of composition for the sensibility image of stimulant was composed by the cause of simplicity characteristics, interesting characteristics, rigid-flexibility characteristics, and modern characteristics. And from these things, the cause of simplicity characteristics and the cause of interesting characteristics were revealed as important dimensional factors of sensibility image. The sensibility image of motif was revealed as a simple image of perfect square, a feminine image of cintamani type, a modern image of mixed rectangular. And black-white colored mixed rectangular and chromatic colored cintamani type were also revealed as an interesting image. The preference rate of motif is related with the cause of interesting characteristics and simplicity characteristics, it also has been revealed to prefer the pale tone than others. And it also has been revealed that achromatic colored mixed rectangular, cintamani type of vivid tone, perfect square and rectangular of pale tone were mostly preferred.

Video composition is to integrate multiple image materials into one scene. It considerably enhances the degree of freedom in producing various scenes. However, we need to adjust the viewing point sand the image planes of image planes of image materials for high quality video composition. In this paper, were propose an intelligent video composition technique concentrating on the composition of CG and real scene. We first model the camera system. The projection is assumed to be perspective and the camera motion is assumed to be 3D rotational and 3D translational. Then, we automatically extract camera parameters comprising the camera model from real scene by a dedicated algorithm. After that, CG scene is generated according to the camera parameters of the real scene. Finally the two are composed into one scene. Experimental results justify the validity of the proposed method.

본 논문에서는 CT영상을 구성하는 RT 알고리즘에 비해 원추형 CB-CT 시스템에서 이용할 수 있는 TPSM 알고리즘을 적용하여 기존의 RT보다 빠르게 3D CT 영상 구성을 할 수 있도록 하였으며 두 개의 알고리즘에 대한 영상속도를 비교분석 하였다. 이를 위하여 원추형 CB-CT 시스템에서 이용할 수 있는 TPSM 알고리즘을 적용하여 3D CT 영상구성에 있어서 실시간 처리가 가능하도록 하였다. 실험결과 TPSM을 이용하여 구성된 단면 영상은 중심점에서 멀어질수록 빈 화소에 의해 영상의 질이 미소하게 감소하지만 TPSM 회전 기반법의 경우에서 영상 구성 속도는 RT알고리즘보다 월등하게 우수하다는 것을 알 수 있었다.

본 논문에서는 일반 사용자가 카메라로 사진을 촬영할 경우에 시선을 집중시키면서 안정적인 구도의 영상을 얻을 수 있는 자동 구도 제시기법을 제안한다. 일반 사용자는 대부분 사진의 구도에 대한 배경지식이 없이 사진을 촬영하고, 촬영된 사진은 피사체의 위치가 적절하지 않아 전문가들이 촬영한 안정적인 구도의 사진과 대조된다. 따라서 비전문가 사용자들에게 촬영 후 영상을 처리하는 방법이 아닌 촬영 시 안정적인 구도를 자동으로 제시해주는 방법을 제공한다. 제안하는 방법은 Saliency Map, Image Segmentation, 윤곽선 검출 등을 통해 피사체를 분석하고 피사체를 안정적인 구도가 구성될 수 있는 위치에 황금분할 가이드라인과 함께 출력한다. 실험결과를 통해 피사체를 분석하고 윤곽선을 검출하여 사용자에게 자동으로 구도가 제시되는 것을 알 수 있다.

본 논문에서는 포아송 영상 편집을 이용한 스테레오 3차원 영상 합성 방법을 제안한다. 3차원 영상을 만들 때 객체의 깊이 값을 고려하지 않고 색상 영상을 합성하면 매우 부자연스러운 결과를 얻는다. 본 논문에서는 그랩컷 방법을 사용하여 추출한 전경 객체를 새로운 배경 영상에 포함시켜 자연스러운 2차원 영상을 만든다. 제안된 방법에서는 기하학적인 위치뿐 아니라 색상 톤도 고려하여 자연스러운 영상을 합성한 후, 합성된 영상의 경계선 주변에 블러링을 수행하여 전경과 배경이 잘 어우러지게 만든다. 이와 더불어, 임의로 주어진 객체의 깊이 값을 이용하여 추출된 객체의 변위를 구하고, 오른쪽 색상 영상과 깊이 영상을 자동으로 합성한다. 실험을 통해, 제안하는 방법이 자연스러운 스테레오 3차원 영상을 생성할 수 있음을 확인했다.
