Abstract(in English) | The dental radiograph is used for diagnosis and individual identification. In the case of diagnosis, the digital subtraction radiography has been used. The projective distortion between two dental radiographs taken from the same patient is caused by the position of X-ray irradiator. For the digital subtraction radiography, the registration of two dental radiographs is required. In this paper, the projective transform is used for the registration. For the projective transform, it is necessary for deriving the transformation function to extract anatomical same points from the reference image and the objective image exactly. In this paper, we propose the methods to extract exact anatomical same points automatically for suitable projective transform. In proposed method, the least-mean-squared method is used for deriving the transformation function because the number of the anatomical same points is given more than six. |
