First Claim
Patent Images

1. A method, comprising:

  • automatically displaying curvature of a spine as a line in an image of the spine;

    wherein automatically displaying the curvature of the spine comprises;

    improving contrast of the image of the spine by generating a mask of the spine and improving the contrast of vertebrae of the spine, wherein generating a mask of the spine comprises finding a region of interest, wherein finding a region of interest comprises;

    dividing the image into a plurality of slices, wherein a width of each slice is equal to a width of the image; and

    a height of each slice is a predetermined number of times smaller than a height of the image;

    for each slice, equalizing a histogram to spread the intensity distribution and applying a threshold of a predetermined percentage of a maximum intensity to raise the contrast;

    shifting each of the slices by one tenth of the height of the slice;

    repeating the steps of dividing, equalizing and shifting a predetermined number of times, obtaining a set of results; and

    calculating a mean of the set of results.
