SUPIR Image Upscaler

Introduction

This workflow is designed for high-quality image upscaling using the SUPIR Upscale (Legacy) method in ComfyUI. It provides advanced image enhancement by refining details, improving resolution, and delivering visually appealing outputs. Perfect for creators looking to enhance their digital images for professional or creative purposes, this workflow ensures a balance between automation and customization, making it suitable for MimicPC users.

SUPIR Overview: Scaling-UP Image Restoration

SUPIR is designed to develop practical algorithms for photo-realistic image restoration in real-world scenarios. It represents a groundbreaking advancement in image restoration, leveraging generative priors and the power of model scaling. By integrating multi-modal techniques with cutting-edge generative priors, SUPIR sets a new standard for delivering intelligent and highly realistic image restoration. The incorporation of model scaling serves as a critical enabler, significantly enhancing the model’s capabilities and unlocking new potential for high-fidelity image recovery and enhancement.

How to Use SUPIR Image Upscale Workflow on MimicPC

1. Set Up the Workflow

Open the ComfyUI interface on MimicPC. Load the provided SUPIR Upscale workflow and ensure the necessary model and checkpoint files are downloaded.

2. Upload the Image

Click "Choose file to upload" in the Load Image node and select your file.

3. Configure the SUPIR Upscale Node

Access the SUPIR Upscale (Legacy) node and configure the parameters as needed:

• Scale by: Adjust the upscaling ratio.
• CFG Scale: Balance the adherence to your prompt.
• Noise Level: Subtle the enhancements.
• Color Fix Type: Use Wavelet to preserve natural colors.

4. Enter the Prompts

In the Prompts section of the SUPIR Upscale node, write prompts to describe the desired enhancement.

Example prompts:

Positive Prompts (Upper column) : masterpices, best quality, finely detail, highres, 8k, beautiful and aesthetic

Negative Promtps (Bottom column): sketches, worst quality, low quality, normal quality, monochrome, grayscale, facing away, looking away, text, error, extra digit, fewer digits, cropped

5. Save the Output

The enhanced image is directed to the Save Image node. Right click and select Save Image.
