Solving Parameters of Affine Transformation Based on ACO

The affine transformation is one of the most key techniques in image registration.Based on analyses for affine transformation model and basic ant colony optimization(ACO),a robust method to approximate the affine transform between two images of a scene was proposed.The proposed algorithm uses the properties of the ACO in continuous space.The new walking strategy and pheromone updating process were described.Some experimental results provided show that the proposed algorithm is effective.
