| Abstract: | In the paper, automatic extraction of affine invariant contour of objects was dealt with. First, six parameters of affine transformation are normalized according to the practical problem in applications. Then, the values of the parameters of affine transformations are computed using a Genetic Algorithm while the energy of contour is referred to as a fitness function. Automatic extraction of affine invariant contour is performed. Finally, experiment results are showed. |
