# Text-guided depth-to-image generation | |
[[open-in-colab]] | |
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](https://github.com/isl-org/MiDaS). | |
Start by creating an instance of the [`StableDiffusionDepth2ImgPipeline`]: | |
```python | |
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, | |
).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: | |
```python | |
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 | |
``` | |
| Input | Output | | |

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