DESCRIPTION:Alexandre De Skowronski\nEDIC candidacy exam\nExam president: 
 Prof. Pascal Frossard\nThesis advisor: Prof. Pascal Fua\nCo-examiner: Prof
 . Cécile Hébert\n\nAbstract\n3D reconstruction from electron microscopy 
 (EM) images is a central topic in computational imaging. Current reconstru
 ction methods\, borrowed from other imaging modalities\, are limited in ha
 ndling low image counts and noise corruption. Recent attempts using neural
  implicit representations and learning-based techniques are discussed. The
  research proposal focuses on incorporating neural implicit functions for 
 memory-effective reconstructions and exploring learning-based regularizati
 on to enhance denoising. Specific priors tailored to different sample type
 s are considered to reduce the number of required images. The abstract emp
 hasizes the need for contrast-agnostic models and addresses the limitation
 s of existing systems.\n\nBackground papers\n1) J. R. Ramirez\, P. Rautek\
