Abstract
An algorithm consisting of a histogram equalisation technique followed by further enhancement using S and π membership functions is described to detect the small variation in grey levels of X-ray images. The effectiveness of the algorithm in identifying the different regional contours related to growth of normal bones is demonstrated.Keywords
