Bootstrap Your Own AV-Proxies: Adaptive Contrastive and Prototype Learning for Audio-Visual Segmentation

The paper introduces BYOAVP, a framework for Audio‑Visual Segmentation that combines adaptive contrastive learning and prototype refinement. It features a Self‑Supervised Audio Enhancement module that aligns audio with visual embeddings, and a Dynamic Prototype Constraint module that updates prototypes to improve pixel‑wise category perception and sounding‑region localization. Experiments show state‑of‑the‑art results on two benchmarks and six sub‑tasks, highlighting strong robustness and cross‑domain generalization.

Frequency-Domain Decomposition and Recomposition for Robust Audio-Visual Segmentation

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.

Shift-Aware Identity-Guided Latent Refinement for Referring Audio--Visual Segmentation

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.

Asymmetric Cross-Modal Fine-Grained Visual Categorization: ACF-Net and the BirdPro Benchmark

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.

Empowering Long-form Omni-modal Understanding with Robust Audio Perception

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.

Semantic-Critical Regions for Video-to-Audio Generation

The paper introduces SCR-V2A, a video-to-audio generation framework that focuses on Semantic-Critical Regions (SCRs)—localized visual cues directly related to sound events. SCR-V2A first identifies these regions via sound-related visual localization, then encodes them with an adapter-based dual visual encoder to produce a control representation that captures both global context and fine-grained sound evidence. This representation conditions an audio generation model, and experiments on in-domain and out-of-domain benchmarks show improved distribution matching and audio quality with few trainable parameters.
