New image registration method based on the physical forces

In this paper, we propose a new method for image registration and template matching in which the registration parameters are translation and rotation. This method is based on the physical forces. The assumption is that images are like charged materials that attract each other, which is a unique feature of the proposed method. In this case, one of the images moves in the same direction as the applied force and the other one is still. The movement of the image continues until the resultant force becomes zero. This approach does not estimate the two parameters separately, but they are estimated simultaneously leading to a better optimized set of registration parameters. We compare the computation cost of this algorithm with other area based methods. In conclusion, we show that the approach is successful and yields to better results than mutual information and correlation-like methods.
