This is a ComfyUI workflow to nudify any image and change the background to something that looks like the input background.

DISCLAIMER: I AM NOT RESPONSIBLE OF WHAT THE END USER DOES WITH IT. ALL THE EXAMPLES IN THE POST ARE BASED ON AI GENERATED REALISTIC MODELS.

Input :

• Image to nudify

• Image of the background to imitate

• Seeds for generation (random or fixed)

• Resolution size (512 by default)

• Number of iterations for the background and foreground generation (It is using Euler for sampling but you can easily go and change it in the flow)

• CFG for background and nudify

• Positive and negative prompts to generate the background and the body

Models used :

• epiCRealism : https://civarchive.com/models/25694/epicrealism

• LORA epicRealismHelper : https://civarchive.com/models/110334?modelVersionId=118945

• stable-diffusion-v1-5 : https://huggingface.co/runwayml/stable-diffusion-v1-5/blob/main/v1-5-pruned-emaonly.ckpt

• 4x Ultrasharp upscaler : https://civarchive.com/models/116225/4x-ultrasharp

What it does :

• Load the inputs

• Resize to processing resolution

• Preprocess the image to nudify by generation masks, pose, depth, prepare color correction...

• Inpaint nudify

• Color correction of the skin

• Generate a new background based on the example in inputs

• Combine the foreground and the background

• Upscaling and saving

A few notes :

• Feel free to finetine the weigths of ControlNet and the FaceSwap node for more precise results

• You can also do more postprocessing of the image if you desire

It uses a few custom nodes like Efficient Loaders and more to accomplish the tasks. Don't forget to install the missing nodes in ComfyUI manager.
