Dual-State Slot Attention: Decoupling Appearance and Identity for Video Object-Centric Learning
Summary
Dual-State Slot Attention (DSSA) is a fully self-supervised framework designed to improve video object-centric learning by addressing limitations in existing slot-based methods. Prior approaches often struggle with maintaining stable object identity in dynamic scenes, such as those with rapid motion or partial occlusion, because they encode both per-frame appearance and cross-frame identity in a single slot vector, leading to objective conflicts and slot swapping. DSSA resolves this by decomposing each slot into a local state for per-frame appearance and a separate identity state for temporal stability. The identity state is updated via a learned recurrent transition acting as a temporal filter, while competition-modulated aggregation (CMA) reduces spurious updates from weakly matching slots. Experiments on MOVi-C, MOVi-D, and YouTube-VIS datasets show DSSA consistently enhances segmentation quality, temporal consistency, object recognition, and video dynamics prediction.
Key takeaway
For Computer Vision Engineers developing robust video analysis systems, Dual-State Slot Attention (DSSA) offers a self-supervised approach to overcome object identity instability. Your implementations should consider decoupling appearance and identity representations, as DSSA demonstrates improved segmentation and temporal consistency across challenging video datasets like MOVi-C, MOVi-D, and YouTube-VIS. This method enhances downstream object recognition and dynamics prediction, providing a more reliable foundation for complex video understanding tasks.
Key insights
Decoupling appearance and identity states significantly improves video object-centric learning stability and performance.
Principles
- Separating appearance and identity representations resolves objective conflicts in video object learning.
- Recurrent temporal filtering on identity states enhances cross-frame consistency.
- Competition-modulated aggregation prevents weak slots from absorbing tokens and destabilizing correspondence.
Method
DSSA decomposes slots into local (appearance) and identity states, updates identity via a learned recurrent transition, and uses competition-modulated aggregation (CMA) to down-weight weak slot updates.
In practice
- Apply DSSA for robust object segmentation in dynamic video environments.
- Utilize DSSA to improve downstream object recognition from video streams.
- Implement CMA to mitigate slot-to-object correspondence issues in slot-based models.
