# CCTV Frame Restoration with Diffusion Model

This demo is an AI-assisted development using **Claude Sonnet 5**.

Restores low-resolution, noisy, low-light CCTV/security camera frames using the pretrained **Stable Diffusion x4 Upscaler** (`stabilityai/stable-diffusion-x4-upscaler`). 

Upload a low-quality frame, adjust the prompt/steps if you like, and get a 4x upscaled, denoised, sharpened result.

**Note:** Input images are resized so their longest side is ≤128px before upscaling, matching the resolution the model was trained on. For CPU inference, it may take 1-3 minutes per image.
