News:

• Jan 8, 2023: Released a pytorch implementation. Check it out here: maxim-pytorch.
• Oct 21, 2022: MAXIM models have been ported to TensorFlow by @sayakpaul. Check it out here: maxim-tf. He also created a couple of Hugging Face Spaces to allow users to quickly try out the different models:
  • Denoising
  • Low-light enhancement
  • Image retouching
  • Dehazing indoors
  • Dehazing outdoors
  • Image deraining
  • Image deblurring
• Sep 8, 2022: our Google AI blog covering both MaxViT and MAXIM is live.
• Apr 25, 2022: Added demos.
  • Colab demo by @deshwalmahesh
  • Replicate web demo .
• Jun 22, 2022: MAXIM selected as 1 of the best paper nomination!
• Mar 29, 2022: MAXIM selected for an oral presentation at CVPR 2022!
