Custom Nodes for ComfyUI: CLIPSeg and CombineSegMasks

This repository contains two custom nodes for ComfyUI that utilize the CLIPSeg model to generate masks for image inpainting tasks based on text prompts.

1. CLIPSeg

The CLIPSeg node generates a binary mask for a given input image and text prompt.

Inputs:

image: A torch.Tensor representing the input image.
text: A string representing the text prompt.
blur: A float value to control the amount of Gaussian blur applied to the mask.
threshold: A float value to control the threshold for creating the binary mask.
dilation_factor: A float value to control the dilation of the binary mask.

Outputs:

tensor_bw: A torch.Tensor representing the binary mask.
image_out_hm: A torch.Tensor representing the heatmap overlay on the input image.
image_out_bw: A torch.Tensor representing the binary mask overlay on the input image.

2. CombineSegMasks

The CombineSegMasks node combines two or optionally three masks into a single mask to improve masking of different areas.

Inputs:

image: A torch.Tensor representing the input image.
mask1: A torch.Tensor representing the first mask.
mask2: A torch.Tensor representing the second mask.
mask3 (optional): A torch.Tensor representing the third mask. Defaults to None.

Outputs:

combined_mask: A torch.Tensor representing the combined mask.
image_out_hm: A torch.Tensor representing the heatmap overlay of the combined mask on the input image.
image_out_bw: A torch.Tensor representing the binary mask overlay of the combined mask on the input image.
