Abstract

A method for the automatic extraction of the soft-tissue facial profile contour is proposed, along with the detection of key cephalometric landmarks based on extremum analysis of a parameterized contour function and subsequent determination of the profile type and its harmony. A variational and numerical analysis of the influence of weighting coefficients in the energy functional on segmentation accuracy and diagnostic indicators is conducted, allowing the parameter selection to be justified and ensuring robust automatic annotation comparable to manual cephalometric analysis

Keywords
