ComfyUI Extension: FreeU_Advanced

FreeU_Advanced Introduction

FreeU_Advanced is an extension designed to enhance the capabilities of AI artists by providing advanced image processing techniques. This extension allows you to apply various multiscale modes and transformations to your images, enabling you to achieve unique and refined visual effects. Whether you are looking to sharpen details, blur certain areas, or enhance edges, FreeU_Advanced offers a range of tools to help you achieve your artistic vision.

How FreeU_Advanced Works

FreeU_Advanced operates by applying different multiscale modes to specific blocks of an image. Think of an image as being composed of multiple layers or blocks, each contributing to the final visual output. By targeting these blocks individually, FreeU_Advanced allows you to apply specific transformations, such as sharpening or blurring, to enhance the overall image.

For example, you can choose to sharpen the edges of an image while keeping the middle part smooth, or apply a Gaussian blur to the background while keeping the foreground in focus. This selective application of effects helps in creating more dynamic and visually appealing images.

FreeU_Advanced Features

FreeU_Advanced comes with a variety of features that you can customize to suit your needs:

• Model Selection: Choose the model you want to patch.
• Target Block: Specify which block to target (input_block, middle_block, or output_block).
• Multiscale Mode: Select from a list of available multiscale modes such as Bandpass, Low-Pass, High-Pass, Gaussian-Blur, Edge-Enhancement, and more.
• Multiscale Strength: Adjust the strength of the scaling effect, ranging from 0.0 to 1.0.
• Array Slice Size: Define the size of the array slice for operations b1 and b2.
• Output Multipliers: Set the output multipliers for b1 and b2.
• Fourier Transform Scale Strength: Adjust the scale strength for Fourier transform operations s1 and s2.

Optional Parameters

• Blending Modes: Choose blending modes for b1 and b2 results, such as bislerp, colorize, cosine interp, and more.
• Blending Strength: Adjust the blending strength for b1 and b2.
• Threshold: Set the threshold value for the Fourier transform function.
• Override Scales: Enable or disable custom scales and experiment with different results.

FreeU_Advanced Models

FreeU_Advanced offers different models that you can use to achieve various effects. Each model is designed to handle specific types of transformations:

• Default Model: Suitable for general-purpose image enhancements.
• Bandpass Model: Ideal for isolating specific frequency bands in an image.
• Low-Pass Model: Useful for smoothing and blurring effects.
• High-Pass Model: Great for edge enhancement and sharpening.
• Gaussian-Blur Model: Applies a Gaussian blur to soften the image.
• Edge-Enhancement Model: Enhances the edges to make them more prominent.
• Sharpen Model: Sharpens the entire image for a crisper look.

What's New with FreeU_Advanced

FreeU_Advanced is continuously updated to improve its features and performance. Here are some of the latest updates:

• New Multiscale Modes: Added new modes like Multi-Bandpass, Multi-Low-Pass, and Multi-High-Pass for more advanced image processing.
• Improved Blending Options: Enhanced blending modes and strengths for more control over the final output.
• Custom Scale Overrides: Introduced the ability to create and use custom scales for more personalized effects. These updates are designed to provide you with more tools and flexibility, making it easier to achieve your desired artistic outcomes.

Troubleshooting FreeU_Advanced

Here are some common issues you might encounter while using FreeU_Advanced and how to solve them:

• Issue: The image looks too blurry or too sharp.
• Solution: Adjust the multiscale_strength parameter to fine-tune the effect. Lower values will reduce the intensity, while higher values will increase it.
• Issue: The effect is not applied to the desired part of the image.
• Solution: Check the target_block setting to ensure you are targeting the correct block (input_block, middle_block, or output_block).
• Issue: Custom scales are not working as expected.
• Solution: Verify that the use_override_scales parameter is set to "true" and that the override_scales string is correctly formatted.
