ComfyUI-BiRefNet-Super

English | 中文

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.

Features

Feature 1: Supports chunked loading on CPU and GPU

When CUDA is enabled, specify the cpu_size to load part of the model onto the CPU.

Feature 2: Model Caching

Feature 3: Multiple Cropping Methods

Supports putalpha, naive, and alpha_matting cropping methods.

News

Nov 19, 2024: Add mask_precision_threshold parameter to control the accuracy threshold of the mask, default to 0.1

Dec 10, 2024:

Add BiRefNet_onnx node to Support onnx model

Modify the name of repository from ComfyUI-BiRefNet-lite to ComfyUI-BiRefNet-Super

Installation

Method 1:

Navigate to the node directory, ComfyUI/custom_nodes/

git clone https://github.com/rubi-du/ComfyUI-BiRefNet-Super.git

cd ComfyUI-BiRefNet-Super

pip install -r requirements.txt

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.

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).
