Tuning-Free Noise Rectification for High Fidelity Image-to-Video Generation

### Model/Pipeline/Scheduler description

Applying pretrained Text-to-Video (T2V) Diffusion models to Image-to-video (I2V) generation tasks using SDEdit often results in low source image fidelity in open domains. This method achieves high source image fidelity in output videos through supplementing more precise source image information using noise interpolation during early denoising steps, resulting in a simple-to-implement, tuning-free, and plug-and-play implementation. The experimental results demonstrate the effectiveness in improving the source image fidelity of generated videos when applied to I2V generation using SDEdit with several different T2V models.

### Open source status

- [ ] The model implementation is available.
- [ ] The model weights are available (Only relevant if addition is not a scheduler).
