The PyCurv library established itself as a valuable tool for curvature estimation in 3D microscopy images. However, in noisy images, the method exhibits visible instabilities, which are not captured by the standard error measures. In this article, we investigate the source of these instabilities, provide ade- quate measures to detect them, and introduce a novel post-processing step which corrects the errors. We illustrate the robustness of our enhanced method over various noise regimes and demonstrate that with our orientation correcting post-processing step, the PyCurv library becomes a truly stable tool for curvature quantification.Keyphrases: curvature estimation, error measures, normal estimation, pycurv, surface orientation, tensor voting In: Varvara L Turova, Andrey E Kovtanyuk and Johannes Zimmer (editors).
