DESCRIPTION

    Prints the polynomials that describe a photoshop curve.
    There are three curves (one per RGB channel) which you can later
    use to make a custom filter for your image.

    See http://www.weemoapps.com/creating-retro-and-analog-image-filters-in-mobile-apps
    for the theory behind this method.
