Hear The Flow: Optical Flow-Based Self-Supervised Visual Sound Source Localization
[article]
2022
arXiv
pre-print
Preserved Fulltext
We further demonstrate that the addition of flow-based attention substantially improves visual sound source localization. ...
In this work, we capture this characteristic by modeling the optical flow in a video as a prior to better aid in localizing the sound source. ...
