The paper introduces ACF-Net, an optical flow‑guided framework for asymmetric audio‑visual fine‑grained visual categorization (FGVC), addressing challenges where video and audio are not strictly synchronized or matched. ACF-Net comprises Optical Flow‑Guided Motion (OFGM) to capture motion‑sensitive visual cues and suppress background noise, and Asymmetric Cross‑Modal Adaptive Fusion (ACAF) to estimate modality reliability and perform uncertainty‑aware fusion. The authors also present BirdPro, a new bird‑oriented audio‑visual benchmark with 1,919 audio recordings and 11,965 videos across 194 species, and report that ACF‑Net outperforms baselines by 2.97% in fused and 1.92% in mismatched settings.

arXiv:2607. 10299v1 Announce Type: new Abstract: Recent advances in large-scale multimodal models have drivenremarkable progress in vision-language tasks; however, comprehensiveomni-modal understanding remains under-explored, largely due to thescarcity of datasets with rich, explicitly aligned auditory cues.

Self-supervised learning from large-scale video data has emerged as a dominant paradigm for visual representation learning. Since audio and visual streams naturally co-occur in video data, extending this success to jointly learn from both modalities is a natural next step, yet it remains challenging.
