1. A method of generating a personalized head-related transfer function (HRTF) on an electronic device, the method comprising:
capturing video data of a user, wherein the video data includes a plurality of views of a head of the user;
processing the video data to extract a plurality of images of the user;
receiving the plurality of images of a user;
processing the plurality of images to generate anthropometric data of the user, wherein processing the plurality of images to generate anthropometric data of the user includes:
identifying key image frames of the plurality of images;
identifying anthropometric features of the user using the key image frames; and
generating the anthropometric data by determining measurements of the anthropometric features; and
inputting the anthropometric data into a HRTF calculation system to obtain the personalized HRTF.
