1. An automated method for determining the positional orientation of radiographic images including a foreground, a background and an object of interest, comprising the steps of:

  • acquiring a digital image of the object of interest;

    segmenting the image to separate the object of interest from the foreground and the background of the image;

    determining a center of the digital image of the object of interest of the segmented digital image;

    adjusting the position of the center of the digital image of the object of interest to coincide with the center of the segmented digital image;

    decomposing the image into one or more strips;

    extracting one or more features of the strips; and

    determining the orientation of the image;

    wherein the step of extracting one or more features of the strips further includes the steps of determining edge density, average density, intensity standard deviation and minimum average intensity of the image.
