1. A computer-implemented method for reconstructing an image, the method comprising: causing an electronic digital computer to receive tomographic data representative of an image signal; causing the electronic digital computer to derive, from the image signal, a plurality of components; causing the electronic digital computer to identify a spatial location associated with maximum phase congruency of the plurality of components; causing the electronic digital computer to incorporate, into an image, an edge at the spatial location; and causing the electronic digital computer to provide an output representative of the image.
