Title:
データベース内の知覚的に最適なＨＲＴＦフィルタを形態学的パラメータに従って選択するための方法
Document Type and Number:
Japanese Patent JP5702852
Kind Code:
B2
Abstract:
A method for selecting a perceptually optimal HRTF in a database according to morphological parameters. A first database includes the HRTFs of subjects M, a second database includes the morphological parameters of the subjects, and a third database corresponds to a perceptual classification of the HRTFs. The N most relevant morphological parameters are sorted by correlating the second and third databases. A multidimensional space is created, which optimizes the spatial separation between the HRTFs according to the classification thereof in the third database to obtain an optimized space. An optimized projection model MPO is calculated for correlating K optimal morphological parameters with the corresponding position of the HRTF filters in the optimized space. For any user whose HRTF is not included in the database, at least one HRTF can be selected from the database BD1 according to the parameters K of the user and the optimized projection model MPO.
