In the ever-evolving world of artificial intelligence and machine learning, the ability to generate and manipulate images has taken a significant leap forward with the advent of generative models like Stable Diffusion. Among the most exciting developments in this field is the integration of ControlNet with OpenPose, creating a powerful tool for controlling and manipulating human poses within images. This article will provide a step-by-step guide on how to use the ControlNet OpenPose model in Stable Diffusion, unlocking new creative possibilities for artists, designers, and hobbyists alike.

What is ControlNet OpenPose?

ControlNet OpenPose is a specialized implementation of ControlNet, a neural network structure that adds extra conditions to control diffusion models. It is specifically conditioned on Human Pose Estimation, which means it can control the generation of images based on the positioning and movement of human figures. OpenPose, on the other hand, is an advanced computer vision library that focuses on real-time human pose estimation. By combining these two technologies, users can now influence the poses of human figures in the images generated by Stable Diffusion.

Setting Up ControlNet OpenPose

Before diving into the creative process, it’s essential to set up the necessary tools and models. But lucky you, DiffusionHub eliminates the confusing installation of some extensions/model, and that is including ControlNet OpenPose.

Here is how to set up ControlNet OpenPose. 

• On the text to image tab,  upload the image with specific pose you aim to achieve (for the best result you can download a real image you can find in the internet) to the ControlNet single image section as shown below

• Enable the ControlNet extension by checking the Enable checkbox.
• Select OpenPose as the control type
• Select “openpose” as the Pre-processor. OpenPose detects human key points like the positions of the head, arms, etc.
• Choose “control_sd15_openpose” as the ControlNet model, which is compatible with OpenPose.

Using ControlNet OpenPose

Now that you have everything set up, let’s walk through the process of creating an image with a custom human pose:

1. Select the Preprocessor and Model: In the Stable Diffusion interface, click on the explosion icon next to the Pre-processor dropdown menu. Choose the OpenPose pre-processor that fits your needs, such as OpenPose, OpenPose_face, or OpenPose_full. Make sure the corresponding ControlNet model is selected in the Model dropdown menu.
2. Edit the Pose: Navigate to the OpenPose Editor tab and use the tools provided to edit the stick figure into the pose you want to replicate in your image. This intuitive interface allows you to adjust the position of limbs and facial features.
3. Generate the Image: Once you’re satisfied with the pose, click on the “Generate” button. The ControlNet OpenPose model will take your edited stick figure and
4. use it as a condition to generate an image that matches the pose you’ve designed.
5. Refine and Experiment: The beauty of ControlNet OpenPose is in its flexibility. You can continue to refine the pose, adjust the prompt, and regenerate the image until you achieve the desired result. This iterative process allows for a high degree of creative control.
