Upscale Images And Prevent The Face From Changing - FOOOCUS

Introduction

When working with image upscaling in FOOOCUS, a common issue that users encounter is that the face in the image tends to change, especially when increasing the size by factors like 1.5x or 2x. This alteration can be quite problematic when the goal is to retain the likeness of the individual. Fortunately, there is a straightforward fix available within a hidden menu in the application.

To resolve this issue, follow these steps:

1. Access Advanced Settings:

   • Start by enabling the developer debug mode in FOOOCUS. This will give you access to more advanced options.

2. Navigate to Debug Tools:

   • Once in developer mode, go to the Debug Tools section of the settings.

3. Adjust Denoising Strength:

   • Scroll down until you find an option labeled Force override of Denoising strength of upscale.
   • By default, this setting is set to -1, which effectively disables it.
   • Change this value to 0.01.

This adjustment is crucial because it allows the software to generate an image that closely resembles the original. There is no need to enter specific prompts or alter any styling options; simply click on generate, and you'll receive an upscaled image that's nearly identical to the original.

To illustrate the effectiveness of this adjustment, let's compare the results:

• Original Image: The face is as it appears before the upscaling process.
• Default Upscale (-1): The result shows a significant change in the facial features, making the person look different.
• Upscale with 0.01: The image generated using the adjustment is almost identical to the original, preserving the likeness effectively.

In conclusion, by simply adjusting one hidden setting, users can ensure that image upscaling does not alter facial features and maintains the integrity of the original subject.
