Abstract

Discrete algorithms for low-level boundary detection are geometrically inaccurate and topologically unreliable. Corresponding continuous methods are often more accurate and need fewer or no heuristics. Thus, we transfer discrete boundary indicators into a continuous form by means of differentiable spline interpolation and detect boundaries using the exact watershed transform. We demonstrate that this significantly improves the obtained segmentations.
