摘要：Dental Radiographs have a valuable aid in the diagnosis of periodontal diseases and the evaluation oftreatment effects. Computer-based image acquisition and processing techniques will now further increase theimportance of radiography in periodontal diagnosis. Digital Subtraction Radiography (DSR) requires a pair of imageswith identical gray-level distribution and projection geometry is needed to identify the periodontal diseases. In DSR, apair of identical images can be obtained without mechanical alignment of patient, film and x-ray source. The drawbackof this technique is, if there is any mechanical alignment in the camera view then mismatching will occur in the result.This paper presents a method for automated diagnosis of periodontal diseases using a single radiographic X-ray imagewhich eliminates the requirement of pair of images.
