Abstract
There is provided a method for generating a personalized Head Related Transfer Function (HRTF). The method can include capturing an image of an ear using a portable device, auto-scaling the captured image to determine physical geometries of the ear and obtaining a personalized HRTF based on the determined physical geometries of the ear.
Claims19
A method comprising:
- changing a template of control points to match a shape model with a captured image of an ear of the individual to form a template of control points of the shape model, wherein the template of control points of the shape model is a visual guide overlaid onto a display of an image capturing device;
- extracting image-based properties of the ear of the individual from the template of control points of the shape model conformed to the captured image of the ear of the individual;
- scaling the image-based properties of the ear corresponding to the captured image of the ear of the individual,
- wherein the scaling uses from the captured image at least one of focal distance data and focal length associated with focusing of the captured image, or a tragus length for the ear in the captured image;
- and
- displaying a preliminary version of the captured image on the display screen.
An article of manufacture including a non-transitory, tangible computer readable storage medium having instructions stored thereon that, in response to execution by one or more processors, cause the one or more processors to perform operations comprising:
- changing a template of control points to match a shape model with a captured image of an ear of the individual to form a template of control points of the shape model, wherein the template of control points of the shape model is a visual guide overlaid onto a display of an image capturing device;
- extracting image-based properties of the ear of the individual from the template of control points of the shape model conformed to the captured image of the ear of the individual;
- scaling the image-based properties of the ear corresponding to the captured image of the ear of the individual,
- wherein the scaling uses from the captured image at least one of focal distance data and focal length associated with focusing of the captured image, or a tragus length for the ear in the captured image;
- and
- displaying a preliminary version of the captured image on the display screen.
A system comprising
- one or more processors;
- and
- a tangible, non-transitory memory configured to communicate with the one or more processors, the tangible, non-transitory memory having instructions stored thereon that, in response to execution by the one or more processors, cause the one or more processors to perform operations comprising:
- changing a template of control points to match a shape model with a captured image of an ear of the individual to form a template of control points of the shape model, wherein the template of control points of the shape model is a visual guide overlaid onto a display of an image capturing device;
- extracting image-based properties of the ear of the individual from the template of control points of the shape model conformed to the captured image of the ear of the individual;
- scaling the image-based properties of the ear corresponding to the captured image of the ear of the individual,
- wherein the scaling uses from the captured image at least one of focal distance data and focal length associated with focusing of the captured image, or a tragus length for the ear in the captured image;
- and
- displaying a preliminary version of the captured image on the display screen.
