Abstract

In this work we propose a system for localization of cephalometric landmarks. The process of localization is carried out in two step: deriving a smaller expectation window for each landmark using a trained neuro-fuzzy system (NFS,) then applying a template-matching algorithm to pin point the exact location of the landmark. The system is trained to locate 20 landmarks on a database of 200 images. Preliminary results show an average of 90% recognition rate.
