ComfyUI-Mosaic

ComfyUI custom nodes for mosaic detection and creation.

Features

• Mosaic Detection: Detect mosaic patterns in images using computer vision
• Mosaic Creation: Create various mosaic effects (squares, circles, hexagons, gradients)
• Pattern Types: Multiple mosaic patterns with customizable parameters
• Mask Support: Apply effects to specific areas using masks

Installation

1. Navigate to your ComfyUI custom nodes directory:

cd ComfyUI/custom_nodes

2. Clone this repository:

git clone https://github.com/1038lab/ComfyUI-Mosaic.git

3. Install dependencies:

cd ComfyUI-Mosaic
pip install -r requirements.txt

4. Restart ComfyUI

Nodes

MosaicCreator

Create mosaic effects on images.

Parameters:

• image: Input image
• mosaic_type: Pattern type (pixelation, blur, block_average, squares, circles, hexagons, gradient_horizontal, gradient_vertical)
• block_size: Mosaic block size (2-100)
• intensity: Effect intensity (0.0-1.0)
• mask: Optional mask for selective application

Outputs:

• image: Processed image
• processing_mask: Applied mask

MosaicDetector
