Look, Listen and Segment: Towards Weakly Supervised Audio-visual Semantic Segmentation

Chengzhi Li, Heyan Huang, Ping Jian +1

Audio-Visual Semantic Segmentation (AVSS) aligns audio and video at the pixel level but requires costly per-frame annotations. We introduce Weakly Supervised Audio-Visual Semantic…
