Description:
    Octave/Matlab utility scripts for image metrics.
    
    *** image_diff.m
    Returns the metrics of the difference between two images as a TSV (Tab-Separated Values) formatted string.
    This function can be used to fill a spreadsheet with the statistics relative to multiple images and multiple methods.
    the optional PREFIX parameter can be used to identify different methods and parameters (this string may include the
    TAB character so it is possible to add several columns).
    All the metrics are normalized, so it is possible to compare the values of images with different size and number of
    layers.
    
    *** image_halfpixref.m
    Generate a reference image to account for the half pixel shift and crop factor introduced by the edge-directed
    interpolation methods like iNEDI that generates images with a size of: NEWSIZE = ((SIZE * 2^ZK) - (2^ZK - 1))
    where ZK is the zoom factor (1 = double size).
