-Even for small images, the pyramid method achieved a speedup of over 100x, while for large images, the computation time is faster than using naive search to align 1 image. More concretely, because the image is downscaled by 2x at each layer of the pyramid, the total image area is less than 1 + (1/2)<sup>2</sup> + (1/4)<sup>2</sup> + (1/8)<sup>2</sup> + ... = 1 + 1/4 + 1/16 + 1/64 + ... &lt; 4/3 of the original.
