Volume-up pads are the most common and easiest way to make women with small breasts beautiful. In this study, to develop a volume-up brassiere pad with excellent wearing effects and appearance, 24 different types of volume-up pads commercially available in the online market were investigated and then 11 types were purchased. Among these eleven types, four pads (PAD1, PAD2, PAD3, PAD4) with distinct shapes and materials were selected through a pre-test. They were compared to the newly developed pad for research (PAD5). The results of the study follow. The results of evaluating appearance when wearing the developed pad (PAD5) were significantly higher than that of other pads, and the appearance evaluation score for the full-cup type pad was excellent. In the wearing satisfaction evaluation result, PAD5 showed generally excellent evaluation scores, and in the case of the touch, preference for the fabric material was higher than that of the silicon pad. In the evaluation of motion adaptability, the developed PAD5 showed generally excellent evaluation scores in all movements, indicating that the full-cup type pads had better motion adaptability than the partial-type pads.

본 논문에서는 정밀한 3차원 복원 및 시점 합성을 위해 매칭 비용을 반복적으로 업데이트하는 Generalized Soft 3D Reconstruction (GenSoft3D) 알고리즘을 제안한다. 먼저 다시점 영상들과 카메라 자세정보가 주어지면 GenSoft3D는 볼륨 기반의 다시점 스테레오 매칭 알고리즘으로 시점별 초기 매칭 비용 볼륨 및 시차 맵을 계산한다. 그 후 정제 과정에서 각 시점은 모든 시차 맵을 이용하여 표면 확률 및 가시 확률을 계산한다. 표면 확률은 초기 매칭 비용 업데이트에 사용하며, 가시 확률은 폐색 영역의 정확한 시차를 계산하기 위해 사용된다. 해당 정제 과정을 일정 횟수 반복할 경우 시점별 고정밀의 시차 맵 획득이 가능하다. 또한 시차 맵의 정확도가 향상됨에 따라 정확한 시점 합성이 가능하다.

Automatic generation of the mid-surfaces of a CAD model is becoming a useful function in that it can help increase the efficiency of engineering analysis as far as it does not affect the result seriously. Several methods had been proposed previously to automatically generate the mid-surfaces, but they often failed to generate the mid-surfaces of complex CAD models. Due to the inherent difficulty of this mid-surface generation problem, it may not be possible to come up with a complete and general method to solve this problem. Since a method that can handle a specific case may not work for different cases, it seems that developing case-specific methods ends up with solving only a fraction of the problem. In this paper, therefore, we propose a method to generate mid-surfaces based on a divide-and-conquer paradigm. This method first decomposes a complex CAD model into simple volumes. The mid-surfaces of the simple volumes are automatically generated by the existing methods, and then they are converted into the mid-surfaces of the original CAD model.
