The three different types of embedded structure alignment described in this work. (a) rCEED aligns two target structures indirectly using a reference structure. This alignment is based on classical Procrustes superimposition. (b) For the detection of outliers and/or common substructures, we use vCEED to perform a local alignment (rather than global in the case of rCEED). (c) If neither a reference structure nor correspondence information is available, we can align the structures using gCEED which adapts a Gaussian mixture model approach for the accurate superimposition.
