Claim 8:
9. A system comprising:
an electron microscope to acquire an image of a sample, the sample including a plurality of regions of interest;
a core, coupled to or included in the electron microscope, including code or coupled to code that, when executed by the core, causes the core to:
initiate a fast marching level set seed within the image;
propagate a fast marching level set curve from the fast marching level set seed to locate boundaries of each of the plurality of regions of interest within the image;
optimize the boundaries of the plurality of regions of interest located via the propagated fast marching level set curve based on active contours or level set algorithms; and
perform metrology on the regions of interest based in part on the boundaries as optimized.
