Method for determining personalized head-related transfer function

A computer-implemented method for determining a personalized head-related transfer function, the method comprising: receiving a training data set comprising one or more training images of one or more ears of a first user, training input vectors indicative of one or more first directions relative to the head of the first user, and one or more second directions indicative of one or more second directions relative to the head of the first user; and one or more values of the personalized head-related directional function associated with the first user and the first direction; training an artificial neural network based on the training data set; receiving an inference data set comprising an inference image of an ear of a second user or a pair of inference images of an ear of the second user, and an inference input vector indicative of a second direction relative to a head of the second user; and processing, by the artificial neural network, the inference data set to predict one or more personalized values of the d
