equations and four unknown parameters that can be writen as

So we have to minimize the quadratic error
e
by using the pseudoinverse of
K
. We show

by the following figure an example of affine motion estimation between two synthetic curves

after contours resampling (
Figure 3
). The final result of curves alignment after affine motion

estimation is presented by
Figure 4
. The estimated motion parameters are presented in
Table

.

Two different shapes after affine deformations ((a) and (c)) and curve resampling

((b) and (d)).
