Contour tracking by minimal cost path approach. application to cephalometry
Résumé
In this paper, a minimal cost approach is used for contour tracking with a good robustness. Dynamic programming was chosen for its efficiency. This general method is applied to the extraction of the cranial contour on high-resolution X-Ray images. As a first step for automated localization of cephalometric points, an ellipse is then fitted on the extracted contour. This method was tested on 424 X-Ray images, with different acquisition parameters.
