Text-guided depth-to-image generation
The StableDiffusionDepth2ImgPipeline lets you pass a text prompt and an initial image to condition the generation of new images. In addition, you can also pass a depth_map
to preserve the image structure. If no depth_map
is provided, the pipeline automatically predicts the depth via an integrated depth-estimation model.
Start by creating an instance of the StableDiffusionDepth2ImgPipeline:
import torch
import requests
from PIL import Image
from diffusers import StableDiffusionDepth2ImgPipeline
pipe = StableDiffusionDepth2ImgPipeline.from_pretrained(
"stabilityai/stable-diffusion-2-depth",
torch_dtype=torch.float16,
use_safetensors=True,
).to("cuda")
Now pass your prompt to the pipeline. You can also pass a negative_prompt
to prevent certain words from guiding how an image is generated:
url = "http://images.cocodataset.org/val2017/000000039769.jpg"
init_image = Image.open(requests.get(url, stream=True).raw)
prompt = "two tigers"
n_prompt = "bad, deformed, ugly, bad anatomy"
image = pipe(prompt=prompt, image=init_image, negative_prompt=n_prompt, strength=0.7).images[0]
image

Play around with the Spaces below and see if you notice a difference between generated images with and without a depth map!
