NAME

       gmerlin_ssim - compare two images

SYNOPSIS

       gmerlin_ssim <image1> <image2> [<output_image>]

DESCRIPTION

       gmerlin_ssim  will  calculate  the  structural  similarity  between  <image1>  and <image2> and store the
       resulting image into <output_image>.

       The input images should be of the same dimension and format.

       The SSIM algorithm is taken from the paper "Image Quality Assessment: From Error Visibility to Structural
       Similarity" by Z. Want et. al.  published in IEEE Transactions on image processing, VOL. 13, NO. 4, APRIL
       2004. Homepage of the author:
