The technique permits reconstruction of features such as structure walls that have a variable thickness, where a thin portion of the wall feature is marginally resolved by an image due to resolution limitations, and the marginally resolved portion of the feature is incompletely segmented. Using the systems, methods, and computer-readable media, such a wall feature can be recognized as a broken wall that misrepresents the completeness of the feature, and can be reconstructed as a completed wall feature.
