Octopus1/page-vitb

PaGE ViT-B Distill

Base distilled student; human-level performance. Part of the PaGE gaze target estimation family.

• —Backbone: DINOv3 ViT-B (derivative of DINOv3, full-parameter trained)
• —Params: ~90M
• —Scene input: 512×512, Head input: 256×256, Heatmap output: 64×64
• —Source checkpoint: vitb_distill.pt

Self-contained weights

This checkpoint includes the full DINOv3 backbone weights in its safetensors files. No external DINOv3 weights are downloaded — the DINOv3 model structure is provided by transformers==5.6.2 (built-in dinov3_vit), and the backbone weights here are derivative weights from full-parameter training of DINOv3. The model code (modeling_page.py) is loaded automatically from `Octopus1/PaGE` via auto_map when you pass trust_remote_code=True.

Installation

pip install torch torchvision timm "transformers==5.6.2" safetensors pillow

Tested with transformers 5.6.2.

Usage

from transformers import AutoModel, AutoImageProcessor
from PIL import Image
import torch

repo = "Octopus1/page-vitb"
model = AutoModel.from_pretrained(repo, trust_remote_code=True).eval()
processor = AutoImageProcessor.from_pretrained(repo, trust_remote_code=True)

scene = Image.open("scene.jpg").convert("RGB")
head = Image.open("head.jpg").convert("RGB")

inputs = processor(scene, head_crops=[head], bboxes=[[(0.10, 0.10, 0.30, 0.40)]])

with torch.no_grad():
    out = model(inputs)

heatmap = out["heatmap"][0]   # [Np, 64, 64]
inout   = out["inout"][0]     # [Np]

Inputs / Outputs

See the family README for the full spec.

• —Input dict: images (list of [B,3,512,512]), head_images (list of [sum(Np),3,256,256]), bboxes (per-image list of (xmin,ymin,xmax,ymax) in [0,1]).
• —Output dict: heatmap (list of [Np,64,64], sigmoid), inout (list of [Np], sigmoid).

License

• —The PaGE decoder and gaze heads are released under the MIT License (see LICENSE).
• —The DINOv3 backbone is a derivative work of DINOv3 (facebook/dinov3). The backbone was initialized from the public DINOv3 self-supervised weights and then trained in full (all parameters updated) as part of PaGE training — i.e. the backbone weights here are derivative weights produced by full-parameter training of DINOv3, not the original DINOv3 weights verbatim.
• —DINOv3 is released by Meta AI under the Meta DINO License (see DINOv3_LICENSE.md). Under its Section 1.b.i, derivative works of DINOv3 (including these backbone weights) are distributed under the DINO License terms, and DINOv3_LICENSE.md must accompany any redistribution.
• —By using or redistributing this model you agree to the DINO License for the DINOv3-derived portions.
