Process of HRTF Individualization by 3D Statistical Ear Model

The use of HRTFs is of well-known importance when it comes to binaural listening. However, easily capturing accurate data is a key point that has not been solved yet. In this paper we present a process for individualizing the HRTFs of an individual using ear photographs. These are fitted to a statistical 3D ear model coupled to a statistical HRTF model. This coupling allows to instantly generate from a given parameterization of the ear model a corresponding set of HRTFs. The accuracy of the results is a direct consequence of the quality and the size of the underlying databases.
