## Summary
Focus is a cornerstone of photography, yet autofocus systems often fail to capture the intended subject, and users frequently wish to adjust focus after capture. This work introduces a novel method for realistic post-capture refocusing using video diffusion models. From a single defocused image, the approach generates a perceptually accurate focal stack, represented as a video sequence, enabling interactive refocusing and unlocking a range of downstream applications.

## Usage
For detailed environment setup, training, and testing instructions, please refer to the official [GitHub repository](https://github.com/tedlasai/learn2refocus). The model utilizes fine-tuned Stable Video Diffusion (SVD) weights.
