Reference-Free Isotropic 3D EM Reconstruction using Diffusion Models

no code implementations3 Aug 2023 Kyungryun Lee, Won-Ki Jeong

Electron microscopy (EM) images exhibit anisotropic axial resolution due to the characteristics inherent to the imaging modality, presenting challenges in analysis and downstream tasks. In this paper, we propose a diffusion-model-based framework that overcomes the limitations of requiring reference data or prior knowledge about the degradation process.
