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
FIGURE 3 Two different shapes after affine deformations ((a) and (c)) and curve resampling
((b) and (d)).
