Quantitative evaluation of uncertainty in acoustic properties is an essential issue to improve product quality. The acoustic properties of porous materials, such as sound absorption coefficient, are affected by variations in microstructure and materi

We propose a new objective function for optimizing a sound-absorbing material layout. The optimization seeks to reduce the average pressure of the domain in the resonance state. The properties of the sound-absorbing material were modeled as an equiva

To suppress artifacts in X-ray digital tomosynthesis, a method which combines 3D and 2D region growing was proposed. However, it could not extract small metals such as pins, due to the discontinuity of the metal in the 3D projection data. A novel met

We propose a new metal artifact correction method for the X-ray digital tomosynthesis by accurately detecting metal in the projection data. We combined 3D region growing for growing a few points in the metal to other projection angles and 2D region g

In this paper, we propose a method that allows users to deform 3D facial model projection images with intuitive parameters for the axes of feature spaces that represent the style used for drawing faces for anime. The spaces are derived from hand-draw
