Mask2Former: Masked-attention Mask Transformer for Universal Image Segmentation

Bowen Cheng, Ishan Misra, Alexander G. Schwing, Alexander Kirillov, Rohit Girdhar

[arXiv] [Project] [BibTeX]


Features

  • A single architecture for panoptic, instance and semantic segmentation.
  • Support major segmentation datasets: ADE20K, Cityscapes, COCO, Mapillary Vistas.

Updates

  • Add Google Colab demo.
  • Video instance segmentation is now supported! Please check our tech report for more details.

Installation
