Egelman EH (1986) An algorithm for straightening images of curved filamentous structures. Ultramicroscopy 19:367–373
Flexible filamentous structures are characterized by variable curvature in electron micrographs. This frequently prevents the direct application of three-dimensional reconstruction methods to helical filaments. An algorithm for straightening the images of such filaments is presented based upon an assumption of a normal mode of bending.
