Abstract
A head-related transfer function (HRTF) generation system includes one or more processors configured to retrieve first image data of a first ear of a subject, compare the first image data with second image data of a plurality of second ears to identify a particular second ear of the plurality of second ears matching the first ear, identify a template HRTF associated with the particular second ear, and assign an HRTF to the subject based on the template HRTF.
Claims17
A method for generating an individualized head related transfer function (HRTF), comprising:
- retrieving, by one or more processors, first image data of a first ear of a subject;
- rotating, by the one or more processors, the first image data so that an orientation of the first image data matches an orientation of second image data of a plurality of second ears;
- comparing, by the one or more processors, the first image data with the second image data of the plurality of second ears to identify a particular second ear of the plurality of second ears matching the first ear;
- identifying, by the one or more processors, a template HRTF associated with the particular second ear;
- and
- outputting, by the one or more processors, the individualized HRTF for the subject based on the template HRTF.

- identifying a first rotational orientation of the first image data and a second rotational orientation of the second image data associated with the particular second ear;
- and
- applying a rotation operation to the template HRTF based on the first rotational orientation and the second rotational orientation;
- and
- outputting, by the one or more processors, the individualized HRTF for the subject based on the template HRTF.
