ComfyUI Seamless Clone Node

A custom node for ComfyUI that implements OpenCV's seamless cloning functionality, allowing you to blend images naturally using Poisson blending techniques.

Features

• Seamless image blending using OpenCV's

• Three blending modes:

  • NORMAL_CLONE: Standard seamless

  • MIXED_CLONE: Mixed seamless cloning that preserves gradients

  • MONOCHROME_TRANSFER: Monochrome transfer mode

• Automatic or manual center point selection

• Compatible with ComfyUI's image processing pipeline

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

Requirements

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