Abstract
Provided is a method and an apparatus for extracting an edge of a distal radius metaphysis. The method includes: setting a region of interest including a distal radius in an X-ray image; setting a potential energy distribution of the region of interest by using a gradient of gray levels; setting a temporary edge adjacent to both sides of a distal radius metaphysis and a side of an epiphysis in the region of interest; and extracting a detailed edge of the distal radius metaphysis having minimum energy by adjusting the set temporary edge using a metropolis annealing technique.
