Run EoMT with Keras 3: JAX, PyTorch, or TensorFlow

kerasformers/eomt_large_coco_instance_640

Paper: Your ViT is Secretly an Image Segmentation Model (arXiv:2503.19108) · HF Papers

EoMT (Encoder-only Mask Transformer) keeps segmentation inside a plain ViT: learned query tokens are concatenated with patch tokens and run through the same ViT blocks. No pixel decoder, no deformable attention decoder.

For more details on the model, please go to the upstream model card.

Pure-Keras 3 conversion of tue-mps/coco_instance_eomt_large_640 for kerasformers. One implementation runs unmodified on TensorFlow / Torch / JAX.

This is a instance checkpoint (EoMTUniversalSegment).

✨ Quick start

import os
os.environ["KERAS_BACKEND"] = "torch"  # or "jax" / "tensorflow"

from PIL import Image
from kerasformers.models.eomt import EoMTUniversalSegment, EoMTImageProcessor

model = EoMTUniversalSegment.from_weights("kerasformers/eomt_large_coco_instance_640")
processor = EoMTImageProcessor.from_weights("kerasformers/eomt_large_coco_instance_640")

image = Image.open("your_image.jpg").convert("RGB")
output = model(processor(image)["pixel_values"], training=False)
result = processor.post_process_instance_segmentation(
    output, target_size=(image.height, image.width)
)
print(result.keys())

Load any EoMT variant the same way with from_weights("kerasformers/<variant>"):

Variant	Hub	Task
`eomt_small_coco_panoptic_640`	`kerasformers/eomt_small_coco_panoptic_640`	panoptic
`eomt_base_coco_panoptic_640`	`kerasformers/eomt_base_coco_panoptic_640`	panoptic
`eomt_large_coco_panoptic_640`	`kerasformers/eomt_large_coco_panoptic_640`	panoptic
`eomt_large_coco_instance_640`	`kerasformers/eomt_large_coco_instance_640`	instance
`eomt_large_ade20k_semantic_512`	`kerasformers/eomt_large_ade20k_semantic_512`	semantic

Tips

Set KERAS_BACKEND before importing Keras / kerasformers.
Use the post-processor that matches the checkpoint task (panoptic / instance / semantic).
