A method for 3D volume segmentation in digitized medical images includes providing a digitized medical image defined on an N-dimensional lattice, obtaining an oriented closed 2-dimensional contour on one or more 2-dimensional slices from said image, defining face weights w from said image intensities by forming a dual lattice of said image lattice, minimizingsummed over all faces subject to the constraint Bz=r wherein vector z is an indicator vector indicating whether a face is present in a minimum-weight surface, vector r is an indicator vector of said 2-D contour, and wherein B is an edge-face incidence matrix, and segmenting said 3-D image into distinct regions separated by the minimum-weight surface indicated by said vector z.
