The digital image contains efficient and useful information which enables measurement and data acquisition. One of the methods that facilitate measuring and interpreting objects, using the image solely, is close-range photogrammetry. Among the various fields of science, whenever a precise measurement is required, this approach can be applied. One of these fields is Medical Sciences that due to ...

Single-particle cryo-electron microscopy is widely used to study the structure of macromolecular assemblies. Tens of thousands of noisy two-dimensional images of the macromolecular assembly viewed from different directions are used to infer its three-dimensional structure. The first step is to estimate a low-resolution initial model and initial image orientations. This is a challenging global o...
