ComfyDeploy: How OpenPose Node works in ComfyUI?

What is OpenPose Node?

This extension contains a custom node for ComfyUI. The node, called 'Bounding Box Crop', is designed to compute the top-left coordinates of a cropped bounding box based on input coordinates and dimensions of the final cropped image. It does so computing the center of the cropping area and then computing where the top-left coordinates would be.

How to install it in ComfyDeploy?

Head over to the machine page

  1. Click on the "Create a new machine" button
  2. Select the Edit build steps
  3. Add a new step -> Custom Node
  4. Search for OpenPose Node and select it
  5. Close the build step dialig and then click on the "Save" button to rebuild the machine

OpenPose Node

This repository contains a Python implementation for extracting and visualizing human pose keypoints using OpenPose models. The OpenPoseNode class allows users to input images and obtain the keypoints and limbs drawn on the images with adjustable transparency. Additionally, it can provide an image with only the keypoints drawn on a black background, and the keypoints value in a JSON format.

Example

Example Workflow BODY_25 Example Workflow COCO You can find the example workflow here

Features

  • Download OpenPose models from Hugging Face Hub and saves them on ComfyUI/models/openpose
  • Process imput image (only one allowed, no batch processing) to extract human pose keypoints.
  • Draw keypoints and limbs on the original image with adjustable transparency.
  • Generate an image with only the keypoints drawn on a black background.
  • Generate JSON with list of keypoints
  • Choose between two OpenPose representations: COCO and BODY_25.

Prerequisites

Ensure you have the following packages installed:

  • torch
  • cv2 (OpenCV)
  • numpy
  • huggingface_hub
  • torchvision

you can install them with

  • pip install -r requirement.txt

or

  • python install.py
