1. A method for detection of bone fractures using image processing of a digitized x-ray image, the method comprising: extracting a contour of a bone in the digitized x-ray image; identifying a bounding box around an area of interest based on the extracted contour of the bone; and applying an adaptive sampling scheme in which the bounding box is divided into a predetermined number of sampling points of a normalized sampling grid such that sampling locations in different images correspond to consistent locations within the area of interest.
