average_affine(1) 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.
