Stable Diffusion ComfyUI With An Awesome AI Background Removal - InSPyReNet

Science & Technology

Introduction

Hello everyone! This is another exciting update on ComfyUI, specifically designed for background removal. Introducing InSPyReNet, a method claimed to be the best to date for removing backgrounds in images with high precision. In this article, we will explore how to install and use InSPyReNet, and compare its performance with other background removal methods like SAM and U-Net.

Installation and Setup

First, click on the ComfyUI Manager where you will find the Custom Nodes Manager. Search for InSPyReNet in the search box and click install. The installation is straightforward. Once installed, restart ComfyUI to load the new custom nodes.

Using InSPyReNet

  1. Load an Image: You need to load an image that you want to process.
  2. Default Settings: The default settings usually work well, without needing adjustments.
  3. Inputs and Outputs: Inputs include the image, and the outputs will be the processed image and the mask.

Side-by-Side Comparison

InSPyReNet retains details such as hair and small gaps in clothing, making the background removal look natural and smooth. Here are comparisons with other methods:

  1. ComfyUI Essentials with UET: Some loss of detail in hair and gaps in clothing.
  2. MTB Nodes with Alpha Mapping: Worse performance with significant loss of detail.
  3. WAS Node Suite using UET: Similar issues with less natural removal.

InSPyReNet shows superior performance in retaining fine details, making it ideal for high-quality images.

Usage Scenarios

  • AI Videos and Movies: InSPyReNet works well for removing backgrounds and adding green screens, similar to movie production techniques.
  • Non-Human Objects: For items like coffee cups or tables, segmentation methods might be more effective.

Conclusion

For detailed image backgrounds, InSPyReNet is highly effective and improves the natural look of the final output. Adjusting settings like the mask kernel size can further enhance the results.
