# TIPSv2 — B/14 DPT Heads

DPT (Dense Prediction Transformer) heads for depth estimation, surface normal prediction, and semantic segmentation on top of the frozen [TIPSv2 B/14](https://huggingface.co/google/tipsv2-b14) backbone. The backbone is loaded automatically. The depth and normals heads are trained on the NYU Depth V2 dataset and segmentation is trained on the ADE20K dataset (150 classes).

| Variant | Vision params | Text params | Embed dim | DPT Heads |

| [g/14](https://huggingface.co/google/tipsv2-g14) | 1.1B | 389M | 1536 | [g/14-dpt](https://huggingface.co/google/tipsv2-g14-dpt) |

## Usage

```bash
pip install transformers torch torchvision sentencepiece
```

```python
from transformers import AutoModel
from torchvision import transforms
from PIL import Image
import requests

model = AutoModel.from_pretrained("google/tipsv2-b14-dpt", trust_remote_code=True)
model.eval().cuda()

url = "https://huggingface.co/spaces/google/tipsv2/resolve/main/examples/depth/ade20k_00014.png"
image = Image.open(requests.get(url, stream=True).raw)
transform = transforms.Compose([transforms.Resize((448, 448)), transforms.ToTensor()])
pixel_values = transform(image).unsqueeze(0).cuda()

# All tasks at once
outputs = model(pixel_values)
print(outputs.depth.shape)         # (1, 1, 448, 448) — depth map
print(outputs.normals.shape)       # (1, 3, 448, 448) — surface normals
print(outputs.segmentation.shape)  # (1, 150, 448, 448) — segmentation logits

# Or individual tasks (only runs the requested head)
depth = model.predict_depth(pixel_values)
normals = model.predict_normals(pixel_values)
seg = model.predict_segmentation(pixel_values)
print(seg.argmax(dim=1).shape)     # (1, 448, 448) — per-pixel class prediction
```
