  • Title: Developing an automatic lateral cephalometric landmark identification program and evaluating its performance.
    Author: Rakhshan V, Rakhshan H, Sheibaninia A.
    Journal: Int J Comput Dent; 2009; 12(4):327-43. PubMed ID: 20108870.
    Abstract:
    PURPOSE: To evaluate the accuracy of detecting cephalometric landmarks automatically by computer. MATERIALS AND METHODS: Digital image processing algorithms (edge-based and morphological) in addition to mathematical algorithms (knowledge-based) were used to develop a program for the identification of 15 lateral cephalometric landmarks on digital cephalograms. RESULTS: The automatic landmark identification system was clinically acceptable (p > 0.05 comparing with 2-mm error range) for five landmarks. CONCLUSION: The automatic landmark identification is accurate for only some landmarks. Additional studies may be necessary to improve this method.
