SimInsert: Seamless Video Object Insertion via Regional Sparse Attention Fusion
The paper presents SimInsert, a novel approach to video object insertion that enhances spatio-temporal coherence and realism without requiring extensive retraining. It utilizes a training-free method that separates the task into single-frame editing and semantic motion description. SimInsert demonstrates superior performance compared to existing methods, achieving significant improvements in key quality metrics.
- ▪SimInsert efficiently decouples video object insertion into intuitive single-frame editing and semantic motion description.
- ▪The approach leverages image-to-video diffusion models to ensure background invariance and plausible interactions.
- ▪SimInsert outperforms state-of-the-art methods, achieving an 18.8% gain in PSNR and a 44.1% decrease in LPIPS.
