Perp-Neg Stable Diffusion

This is the repository for using Perp-Neg sampling with Stable Diffusion model, as presented in Re-imagine the Negative Prompt Algorithm: Transform 2D Diffusion into 3D, alleviate Janus problem and Beyond..

Running code

Run compositional ebm with diffusion model

python scripts/image_sample_stable_diffusion.py --prompt="a boy wearing sunglasses|sunglasses with black frame" --weights="1|-1.5" --pipeline='cebm' --num_images=1

Run PerpNeg

python scripts/image_sample_stable_diffusion.py --prompt="a boy wearing sunglasses|sunglasses with black frame" --weights="1|-1.5" --pipeline='perpneg' --num_images=1

Run PerpNeg-rotation

python scripts/image_sample_stable_diffusion.py --prompt="a photo of lion, front view | a photo of lion, side view" --weights="1|-1.5|-1.5" --pipeline='rotation_perpneg' --num_images=1

PerpNeg-Stable DreamFusion

please use the scripts in stable-dreamfusion/scripts/run_if2_perpneg.sh to run the Stable DreamFusion + PerpNeg to avoid the Janus problem.

This code is manily based on Stable-DreamFusion
