Denoising Strength Parameters

A parameter controlling how much an input image is modified during img2img or inpainting. Higher values allow more change from the original.

Denoising strength determines the balance between preserving your input image and allowing the AI to create something new.

How It Works

The value (0.0 to 1.0) controls how much noise is added:

  • 0.0: No noise added, output equals input
  • 0.5: Half the noise of txt2img
  • 1.0: Full noise, like starting from scratch
