Shkolnisky, “A common lines approach for ab initio modeling of molecules with tetrahedral and octahedral symmetry,” SIAM J. on Imaging Sciences, vol. 16, no. 4, pp. 1978–2014, 2023.<br /> <br /> == Abstract ==<br /> <br /> A main task in cryo-electron microscopy single particle reconstruction is to nd<br /> a three-dimensional model of a molecule given a set of its randomly oriented and<br /> positioned noisy projection-images. In this work, we propose an algorithm for ab-initio<br /> reconstruction for molecules with tetrahedral or octahedral symmetry. The algorithm<br /> exploits the multiple common lines between each pair of projection-images as well as<br /> self common lines within each image. It is robust to noise in the input images as it<br /> integrates the information from all images at once. The eciency of the proposed<br /> algorithm is demonstrated using experimental cryo-electron microscopy data.<br /> <br /> == Keywords ==<br /> <br /> == Links ==<br /> <br /> https://epubs.siam.org/doi/abs/10.1137/22M150383X<br /> <br /> == Related software ==<br /> <br /> == Related methods ==<br /> <br /> == Comments ==</div>
