Image Remove Bg(imageRemBg)

Description

The Image Remove Bg node removes the background from input images and returns both the cut-out image and a corresponding alpha mask. It is part of the EasyUse/Image category.

Inputs

• images (IMAGE): The input image or batch of images to process.

• rem_mode (COMBO): The background-removal model to use. Options:

  • RMBG-2.0
  • RMBG-1.4
  • Inspyrenet
  • BEN2

  Defaults to RMBG-1.4.

• image_output (COMBO): Controls how the resulting image is handled. Options:

  • Hide — Do not show the output image in the UI.
  • Preview — Show the output image in the UI.
  • Save — Save the output image to disk.
  • Hide/Save — Hide the preview and save the image to disk.

  Defaults to Preview.

• save_prefix (STRING): The filename prefix used when the output image is saved. Defaults to ComfyUI.

• torchscript_jit (BOOLEAN, optional): Enables TorchScript JIT inference when supported by the selected model. Defaults to false.

• add_background (COMBO, optional): Adds a solid background color to the result after background removal. Options:

  • none
  • white
  • black

  Defaults to none.

• refine_foreground (BOOLEAN, optional): Enables additional foreground refinement for cleaner edges and detail. Defaults to false.

Outputs

• IMAGE: The processed image with the background removed, or with the selected solid background applied.
• MASK: The alpha mask representing the removed background.

Usage Notes

The rem_mode selection changes the underlying background-removal model, so different modes may produce different results depending on the subject matter. Use image_output to control whether results are previewed, saved, or both. The save_prefix is only relevant when an output mode that includes saving is selected. torchscript_jit can improve inference speed on supported setups, while refine_foreground is useful when the default mask leaves rough edges around the subject.
