ADE20K probe on DINOv3 ViT-B/16 at 128 px

A linear ADE20K semantic segmentation probe on frozen DINOv3 ViT-B/16 features at 128 px, a passive-vision reference for CanViT, trained with the paper's probing protocol.

CanViT, the Canvas Vision Transformer, is an active-vision foundation model: it sees a scene through a sequence of glimpses and remembers it on a scene-wide canvas.

Usage

uv add "canvit-pytorch>=0.2" transformers

import torch
from PIL import Image
from canvit_pytorch.preprocess import preprocess
from canvit_pytorch.probes import SegmentationProbe
from canvit_pytorch.teacher import load_teacher

dinov3 = load_teacher("facebook/dinov3-vitb16-pretrain-lvd1689m", torch.device("cpu"))
probe = SegmentationProbe.from_pretrained("canvit/probe-ade20k-40k-dv3b-128px").eval()
scene = preprocess(128)(Image.open("scene.jpg").convert("RGB")).unsqueeze(0)  # [1, 3, 128, 128]

with torch.inference_mode():
    patches = dinov3(scene).patches.unflatten(1, (8, 8))  # [1, 8, 8, 768]
    logits = probe(patches)  # [1, 150, 8, 8]
