Automatic Detection of Bone Contours in X-Ray Images

Detection of bone contours in x-ray images is an important step in the computer analysis of medical images. Analog X-ray images are characterized by low contrast ratio value and high variability of their optical properties. Therefore classical segmentation algorithms based on homogeneity criteria are not applicable. In this paper we propose an approach for automatic bone contours detection which does not require homogeneity of regions. This method is based on accurate edge fragments detection and elimination of discontinuities between them. We have dened the criteria for calculating numerical characteristics of the quality of image contours detection. The obtained results are used for diagnosis of abnormalities and diseases of the detected object.
