NAME

       average_affine - Average affine transformations

SYNOPSIS

       average_affine [options] x0 [x1 ...]
        WHERE  x0  ...  xN  is  [{-i,--inverse}]  affine  transformation  #. (If the first transformation in the
       sequence is inverted, then '--inverse' must be preceded by '--', i.e., use '-- --inverse xform.path').

DESCRIPTION

       This tool computes the average of a sequence of user-provided affine coordinate transformations.
