SUPIR Quickstart Guide: Effective Image Restoration & Enhancement

SUPIR (SUPer Image Restoration) is a versatile AI model designed for photo-realistic restoration, super-resolution, noise reduction, and historical B&W enhancement. This guide walks you through key parameters and recommended settings for popular use cases.

1. Core Workflow

1. Provide a high-quality URL or local path for the image input.
2. Choose your model_name:
   • SUPIR-v0Q (default): Balanced quality vs. speed
   • SUPIR-v0F: Highest fidelity at the cost of extra compute
3. Adjust general parameters (see below).
4. Launch batch jobs or single-shot runs via the Segmind API, Hugging Face, or GitHub integration.

2. Essential Parameters

• upscale (int): Output multiplier. 1 = no change, 2 = 2× resolution, etc.
• edm_steps (int, default 50): Number of diffusion steps. Increase to 100–150 for extra detail (at longer runtime).
• s_cfg (float, default 7.5): Guidance strength for text prompts. Higher values enforce prompts more strictly.
• a_prompt / n_prompt: Positive and negative text hints.
  – Example a_prompt: “Cinematic, ultra HD, high contrast, extremely detailed.”
  – Example n_prompt: “low quality, artifacts, watermark, blurry.”

3. Use Case Presets

1. General Photo Restoration

   • model_name: SUPIR-v0Q
   • upscale: 1
   • edm_steps: 50
   • s_cfg: 7.5
   • color_fix_type: Wavelet
   • a_prompt: “photo realistic, vibrant color, super detailed”
   • n_prompt: “noise, blur, artifacts”

2. Low-Light / Noisy Shots

   • edm_steps: 75
   • s_noise: 1.005 (slightly higher for robust denoising)
   • s_churn: 4 (stabilizes heavy noise removal)
   • a_prompt: “clean, sharp, high fidelity”
   • n_prompt: “grain, excessive noise, blur”

3. Super-Resolution (Upscaling)

   • upscale: 2 or 4 (based on target)
   • edm_steps: 100
   • s_cfg: 9–12 (stronger guidance for fine detail)
   • color_fix_type: AdaIn (for color fidelity on large scaling)

4. Historical B&W Restoration

   • use_llava: true (auto-generates context captions)
   • color_fix_type: Wavelet
   • a_prompt: “vivid colorization, realistic skin tones, natural lighting”
   • n_prompt: “over saturation, unnatural hues”
   • edm_steps: 60

4. Advanced Tips

• Seed control: Set seed for reproducible batches; leave blank for random diversity.
• Linear CFG & Staged Control: Enable linear_CFG or linear_s_stage2 for gradual adjustments across diffusion sigma. Great for extreme restoration.
• Keep originals: Always archive the source files for comparison and audit.
• Batch scripting: Use CLI or Python SDK to iterate parameters programmatically and identify optimal configurations.

By following these presets and best practices, you can maximize SUPIR’s capabilities and achieve consistent, high-quality results across diverse image restoration challenges.
