Magnitude Modeling of Personalized HRTF Based on Ear Images and Anthropometric Measurements
Applied Sciences, 2022 In this paper, we propose a global personalized head-related transfer function (HRTF) method based on anthropometric measurements and ear images. The model consists of two sub-networks. The first is the VGG-Ear Model, which extracts features from the ear
