This paper describes the Active Shape model for automatic segmentation of cephalograms image using contour lines. Cephalogram image is a X-ray image of human head. It is also a radiograph of an image. The aim of our project is to evaluate an automatic segmentation of cephalograms image using contour based ASM. Cephalometry is used to assess craniofacial growth and devolpment of human head. Craniofacial is nothing but the medical term that relates to bones of the skull. A contour line is a function of two variables that is curve along which the function has a constant value. In this project we use this contour lines which gives the accurate image segmentation.ASM method improves the point location in an image. In previous method they achieved only 95% of accuracy. So we increase the accuracy using contour based ASM.
