Two Datasets Are Better Than One: Method of Double Moments for 3-D Reconstruction in Cryo-EM
Researchers have developed a novel data fusion framework called the method of double moments (MoDM) for reconstructing 3-D molecular structures from cryo-electron microscopy images. This method leverages two distinct sets of second-order moment statistics derived from projection images captured under different orientation distributions. The framework proves that these moments can uniquely determine the molecular structure, and an algorithm based on convex relaxation achieves accurate recovery using only these second-order statistics.
