Abstract – The assessment of cranio-facial structures forms a part of orthodontic diagnosis. The medical procedure of marking landmarks on the standardized X-Ray of the face and finding the distances and angles between the landmarks in order to calculate the facial proportions is known as Cephalometric Analysis. The traditional method of manually marking the landmarks on a tracing paper placed over the Cephalogram (standardized X-Ray of the face) and making the scale measurements was vulnerable to errors. The evaluation prone errors were dealt by the semi-automatic software solution. This report talks about the project which aims at developing an algorithm which can automatically and intelligently mark the Anatomic landmark points on the digitally scanned cephalogram.
