The three-dimensional morphological database for spatial hearing research of the BiLi project

Abstract

The BiLi Project is a French collaborative project concerned with binaural listening and improved rendering for the general public. One of the goals of this project is to develop simple methods to personalize Head-Related Transfer Functions based on people's morphology. In order to accomplish this, it is necessary to study the links between an individual's HRTF and their corresponding morphology. As a resource for studies relating these parameters two databases have been created: a database of high resolution measured HRTFs and an accompanying database of 3D morphological data. This work presents the details of the creation of the morphological database. The prerequisites for such a database are presented. Various technical solutions are proposed and evaluated. Resulting accuracies of the methods are compared using extracted morphological parameters as defined in the CIPIC database with those measured directly on the individuals.
