Benefits of technology

The patent text describes a method for creating a personalized Head Related Transfer Function (HRTF) by capturing an image of an ear using a portable device, and then processing it to determine the physical geometries of the ear. This information is then used to create a personalized HRTF, which can help to make virtual or augmented reality experiences more immersive and realistic.

Problems solved by technology

However, it is appreciable that the above discussed approaches / techniques would require much resource in terms of computing power.
Moreover, the above discussed approaches / techniques may not facilitate the creation of personalized HRTF(s) is a user friendly and / or efficient manner.

Embodiment Construction

[0018]The present disclosure relates to a method 100 (as will be shown in further detail with reference to FIG. 1) for creating / generating a personalized / customized Head Related Transfer Function (HRTF) from an image captured using a portable device such as a Smartphone having a camera. The present disclosure contemplates that the prior art technique concerning Hough transform is the simplest as compared the prior art technique which relates to the reconstruction of a detailed ear model from multiple photos and the traditional approach involving the use of an anechoic chamber. The present disclosure further contemplates the need to further simplify the prior art technique concerning Hough transform so as to at least facilitate the creating / generating personalized HRTF(s) in a user friendly and / or efficient manner.

[0019]Referring to FIG. 1 a method 100 for creating / generating a personalized / customized HRTF is shown in accordance with an embodiment of the disclosure. Specifically, a p...

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.

Description

FIELD OF INVENTION[0001]The present disclosure generally relates a method for generating a customized / personalized Head Related Transfer Function (HRTF) based on a captured image.BACKGROUND[0002]Accurate interactive 3D spatial audio rendering requires personalized head-related transfer functions (HRTFs).[0003]Traditionally to obtain such personalized HRTFs, a user is required to sit, without moving, for about half an hour in an anechoic chamber with audio signals being emitted from different locations within the chamber. A microphone is placed in the user's ear for capturing audio signals as audibly perceived by the user. There is also need to consider factors such as chamber, audio signal source(s) and microphone responses. Such responses may be considered spurious responses and there may be a need to eliminate such spurious responses in order to obtain a Head Related Impulse Response (HRIR) which can subsequently be converted to a HRTF.[0004]Prior art techniques have emerged to si...
