A Geometric Deep Learning Approach to Sound Source Localization and Tracking (2023)
Abstract / truncated to 115 words
The localization and tracking of sound sources using microphone arrays is a problem that, even if it has attracted attention from the signal processing research community for decades, remains open. In recent years, deep learning models have surpassed the state-of-the-art that had been established by classic signal processing techniques, but these models still struggle with handling rooms with strong reverberations or tracking multiple sources that dynamically appear and disappear, especially when we cannot apply any criteria to classify or order them. In this thesis, we follow the ideas of the Geometric Deep Learning framework to propose new models and techniques that mean an advance of the state-of-the-art in the aforementioned scenarios. As the input of ... toggle 6 keywordsdeep learning – microphone arrays – audio signal processing – localization – tracking – sound source localization
