Abstract

A morphological filtering algorithm based on the Minkowski Functionals in 3D for segmentation of macromolecular structures in intact eukaryotic cells depicted by cryo-electron tomography, was proposed. The 3D image data of an ice-embedded Dictyostelium amoeba directly grown on an electron microscopy grid was analyzed. The specimen is scanned by low dose transmission electron microscopy employing a CM 300 FEG TEM with a single axis tilt series of -50° to + 41.5° at an increment of 1.5°. A 3D reconstruction is obtained by weighted back-projection. Mathematical topology employs additive image functionals, to assign numeric quantities to the shape and connectivity of patterns formed by the pixels in an image.
