Abstract
A head-related transfer function personalized algorithm based on Locally Linear Embedding is proposed for the precise localization of human beings with different physiological parameters. HRTF data was processed to reduce dimensionality by Locally Linear Embedding at first and linearly fitted in the low-dimensional space to extract the representative HRTF. Correlation analysis was used to select the physiological parameters which had a great influence on HRTF. The nonlinear mapping between physiological parameters and the representative HRTF was established by Artificial Neural Network, and then the individual HRTF can be calculated by a small number of body parameters. The experimental results show that the proposed algorithm can achieve personalized HRTF quickly and accurately, and solves the problem that personalized HRTF is difficult to measure.
