The paper introduces Frequency-Aware Audio-Visual Segmentation (FAVS), a framework that treats audio-visual segmentation as a frequency-domain decomposition and recomposition task. It comprises a Frequency-Domain Enhanced Decomposer (FDED) that iteratively separates modality-specific semantics and structural features, and a Synergistic Cross-Modal Consistency (SCMC) module that uses a mixture-of-experts architecture to maintain semantic consistency and preserve modality-specific features. Experiments on three benchmark datasets show that FAVS achieves state-of-the-art performance, with qualitative visualizations supporting the effectiveness of both modules.

The paper introduces Shift-Aware Identity-guided Latent (SAIL) refinement for Referring Audio‑Visual Segmentation (Ref‑AVS), a task that requires precise segmentation of a specific object using both visual and auditory cues grounded in natural language. SAIL employs a dual‑token strategy to separate frame‑level dynamics from a global semantic anchor, a shift‑aware refinement module to correct target‑shift drift, and a decoder with continuous memory updates to preserve spatio‑temporal coherence and identity consistency. Experiments on two Ref‑AVS benchmarks show that SAIL outperforms existing AVS, Ref‑VOS, and Ref‑AVS methods.

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.
