EoMT-DINOv3

Overview

The EoMT-DINOv3 family extends the Encoder-only Mask Transformer architecture with Vision Transformers that are pre-trained using DINOv3. The update delivers stronger segmentation quality across ADE20K and COCO benchmarks while preserving the encoder-only design that made EoMT attractive for real-time applications.

Compared to the DINOv2-based models, the DINOv3 variants leverage rotary position embeddings, optional gated MLP blocks and the latest pre-training recipes from Meta AI. These changes yield measurable performance gains across semantic, instance and panoptic segmentation tasks, as highlighted in the DINOv3 model zoo.

The original EoMT architecture was introduced in the CVPR 2025 Highlight paper Your ViT is Secretly an Image Segmentation Model by Tommie Kerssies, Niccolò Cavagnero, Alexander Hermans, Narges Norouzi, Giuseppe Averta, Bastian Leibe, Gijs Dubbelman and Daan de Geus. The DINOv3 upgrade keeps the same lightweight segmentation head and query-based inference strategy while swapping the encoder for DINOv3 ViT checkpoints.

Tips:

• The configuration exposes DINOv3-specific knobs such as rope_theta and use_gated_mlp. Large DINOv3 backbones such as dinov3-vitg14 expect use_gated_mlp=True.
• DINOv3 models can operate on a broader range of resolutions thanks to rotary position embeddings. The image processor still defaults to square crops but custom sizes can be supplied through AutoImageProcessor.
• The pre-trained checkpoints hosted by the TU/e Mobile Perception Systems Lab provide delta weights that should be combined with the upstream DINOv3 backbones. The conversion utilities in the official repository describe this workflow in detail.

Usage examples

Below is a minimal example showing how to run panoptic segmentation with a DINOv3-backed EoMT model. The same image processor can be reused for semantic or instance segmentation simply by swapping the checkpoint.

import requests
import torch
from PIL import Image

from transformers import AutoImageProcessor, AutoModelForUniversalSegmentation


model_id = "tue-mps/eomt-dinov3-coco-panoptic-base-640"
processor = AutoImageProcessor.from_pretrained(model_id)
model = AutoModelForUniversalSegmentation.from_pretrained(model_id).to("cuda" if torch.cuda.is_available() else "cpu", device_map="auto")

image = Image.open(requests.get("http://images.cocodataset.org/val2017/000000039769.jpg", stream=True).raw)

inputs = processor(images=image, return_tensors="pt").to(model.device)

with torch.inference_mode():
    outputs = model(**inputs)

segmentation = processor.post_process_panoptic_segmentation(outputs, target_sizes=[image.size[::-1]])[0]
list(segmentation.keys())
['segmentation', 'segments_info']
