<h1 align="center">ComfyUI-BiRefNet-Super</h1> <p align="center"> <br><font size=5>English</font> | <a href="README_CN.md">中文</a> </p>

Introduction

This repository packages the latest BiRefNet model as a ComfyUI node for use, supporting chunked loading on both CPU and GPU, as well as model caching features.<br>

Features

Feature 1: Supports chunked loading on CPU and GPU<br>
When CUDA is enabled, specify the cpu_size to load part of the model onto the CPU.
<br>
Feature 2: Model Caching<br>
Feature 3: Multiple Cropping Methods<br>
Supports putalpha, naive, and alpha_matting cropping methods.
<br>

News

• Nov 19, 2024: Add mask_precision_threshold parameter to control the accuracy threshold of the mask, default to 0.1<br>
• Dec 10, 2024:
  • Add BiRefNet_onnx node to Support onnx model <br>
  • Modify the name of repository from ComfyUI-BiRefNet-lite to ComfyUI-BiRefNet-Super<br>

Installation

Method 1:

1. Navigate to the node directory, ComfyUI/custom_nodes/
2. git clone https://github.com/rubi-du/ComfyUI-BiRefNet-Super.git
3. cd ComfyUI-BiRefNet-Super
4. pip install -r requirements.txt
5. Restart ComfyUI

Method 2:

Directly download the node source code package, unzip it into the custom_nodes directory, and then restart ComfyUI.

Method 3:

Install via ComfyUI-Manager by searching for "ComfyUI-BiRefNet-Super".

Usage

BiRefNet_Super | BiRefNet_Lite

Example workflows are placed in ComfyUI-BiRefNet-Super/workflow.<br/>

There are two options for loading models: one is to automatically download and load a remote model, and the other is to load a local model (in which case you need to set load_local_model to true and set local_model_path to the local model path under the models/birefnet directory, for example, the BiRefNet folder).<br/>

Workflow Address

BiRefNet_onnx

Example workflows are placed in workflow.<br/>

Place the model file in ComfyUI/models/birefnet.<br/>

Model file name should be one of the following:

• birefnet-general.onnx
• birefnet-general-lite.onnx
• birefnet-portrait.onnx
• birefnet_massive.onnx
• birefnet-hrsod.onnx
• birefnet-dis.onnx
• birefnet-cod.onnx
