Recolor Old Photo Restoration Workflow

This workflow utilizes multiple ControlNet, allowing for global and local analysis of images, extracting key features (such as brightness, contrast, color), and fine-tuning parameters through skeleton analysis functionality. Combined with Stable Diffusion's detail restoration capability and ControlNet's enhancement features, it can first restore the structure and texture of old photos and then optimize the overall visual effect.

Recolor functionality achieves intelligent coloring, automatically generating realistic colors for black-and-white old photos without the need for complex prompt words, enabling one-click coloring.

ControlNet ensures that the restored images maintain high consistency with the original photos in core elements such as character poses and scene layouts by constraining the feature space of the generation process, avoiding common structural distortion issues in AI-generated images.
