comfyui-seamless-clone

Installation

1. Navigate to your ComfyUI custom nodes directory:

cd ComfyUI/custom_nodes/

2. Clone this repository:

git clone https://github.com/Aksaz/comfyui-seamless-clone

3. Install the required dependencies:

pip install -r requirements.txt

Usage

The node accepts the following inputs:

• source_image: The image to be cloned (foreground)

• destination_image: The target image (background)

• mask_image: A binary mask defining the region to be cloned

• blend_mode: Choose between NORMAL_CLONE, MIXED_CLONE, or MONOCHROME_TRANSFER

• center_x: X-coordinate of the clone center (optional)

• center_y: Y-coordinate of the clone center (optional)

Output:

• cloned_image: The resulting seamlessly blended image

Important Notes

• Image Proportions: The node automatically resizes the source image and mask to match the destination image dimensions to prevent boundary errors.
• Center Point Validation: If center coordinates are provided, they are automatically clamped to valid image boundaries.
• Fallback Mode: If seamless cloning fails due to complex geometry or boundary issues, the node automatically falls back to simple alpha blending.
• Mask Validation: The mask is automatically cropped to ensure it fits within the destination image bounds.

Troubleshooting

Common Issues

1. "Mask is empty after processing": Ensure your mask contains non-zero values in the region you want to clone.

2. "No valid mask pixels found": Check that your mask image has visible content in the areas you want to clone.

3. Seamless cloning falls back to alpha blending: This is normal behavior when the geometry is too complex for seamless cloning. The result will still be a blended image, though without the advanced Poisson blending.

Best Practices

• Use masks with clear, well-defined boundaries for best results
• Ensure the source image has good contrast with the destination image
• For complex shapes, consider using the MIXED_CLONE mode which preserves gradients better

Requirements

• numpy==2.2.0
• opencv_python==4.10.0.84
• torch==2.5.1
