What is VISION XL
VISION XL is an efficient video restoration and super-resolution tool based on latent diffusion model technology, focused on solving inverse problems for high-definition video. The tool can repair missing parts of videos, remove blur, and improve video clarity, with up to 4x super-resolution. VISION XL is based on reducing dependence on additional pre-trained modules and optimizes processing efficiency. It requires only 13GB of VRAM and can process 25 frames of video within 2.5 minutes, making it very suitable for application scenarios that require rapid video processing.
Main Features of VISION XL
- Video Deblurring (Deblur): Removes blur in videos caused by unstable shooting or other reasons, restoring video clarity.
- Super-Resolution (SR): Increases video resolution to four times the original, enhancing video details and quality.
- Video Inpainting: Repairs damaged parts in videos and restores lost information.
- Frame Averaging: Supports averaging multiple frames of video to reduce noise and improve video stability.
- Multiple Types of Spatial Degradation Processing: Handles other types of spatial degradation problems.
Technical Principles of VISION XL
- Latent Diffusion Models: Based on latent diffusion models, the iterative denoising process restores clear images or videos from noisy data.
- Pseudo-Batch Consistent Sampling: Introduces a pseudo-batch consistent sampling strategy to improve processing efficiency.
- Batch-Consistent Inversion: Inverts measurement frames and duplicates them, providing a good temporal consistency initialization and reducing overall sampling time.
- Multi-Step Conjugate Gradient (CG): Performs multi-step conjugate gradient optimization in the pixel (decoding) space of the Tweedie denoising batch to solve video inverse problems.
- Scheduled Low-Pass Filtering: Used when re-encoding the optimized video into the latent (encoding) space to maintain data consistency.
- Parallel Sampling Process: Performs parallel sampling on the latent representation of each frame to obtain a pseudo-batch of Tweedie denoising, ensuring spatiotemporal data consistency.
