Image Registration Method Based on Physical Forces for Color Images
Ali Ghayoor, Amin Sadri, Ali Asghar Beheshti Shirazi · 2010
A new method for image registration has been previously proposed by the authors, which the registration is based on physical forces. The registration parameters are translation and rotation. This method assumes images like charged materials that attract each other. In this case, one of the images moves in the same direction as the applied force while the other one is still. The movement of the image continues until the resultant force becomes zero. This approach estimates the registration parameters simultaneously and leading to a better optimized set of registration parameters. The previous work is presented for grayscale images, and in this paper we aim to develop this method for color images. The comparison of the results shows that the excess information which exists in color images can accelerate the registration process. Also, we find the optimum set of the parameters to improve the accuracy of the algorithm.
