The figure 8 represents an image Lizard which has been submitted to
six rotations from 
to 
in the image plane.
The results on the figure 9 show clearly
that the characterization with the feature vector 
is invariant to rotation in a
robust way. According to the number of correct matches to be found, we are able to obtain more than
90 
of correct matches in most of cases, whatever the rotation applied. To realize the matching,
we have used the method of comparison vector described at section 4.1 and the
relaxation technique introduced at section 4.2.

the rotation applied, we are able to match correctly 90 couples of Harris points.
