| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | With recent progress in computational resources and 3D-scanning techniques, numerical simulations become a practical way to obtain head-related transfer function (HRTFs). Previous studies have shown that the HRTFs can be obtained by numerical simulations if an accurate geometry of the head and pinna shapes is provided. However, the acquisition of an accurate geometry of the head and pinna shapes requires a precise scanning technique such as a magnetic resonance imaging {it etc.}, which leads to a lot of cost in obtaining individualized HRTFs necessary for an accurate binaural synthesis. To solve this problem, we have been invesitgating on an acquisition of individualized 3D head model by morphing based on 2D images of the head and pinnae for HRTF simulation. This paper introduces a method of generating individualized 3D head model by applying 3D morphing based on 2D image of individual head to a standard head model (dummy head). As a result, HRTF calculated from the model have no pinnas indicated individualized amplitude-frequency characteristics and interaural time differences. |
