1. A computer-implemented method for assessing image quality, comprising: acquiring a first image and a second image, wherein at least a portion of the first image and the second image overlap; determining a rotation and a scale relating the first image and the second image; rotating and scaling a respective Fourier transform of the first image to correspond to a respective Fourier transform of the second image; determining a translation for the respective first image and the second image based upon the rotated and scaled Fourier transforms of the first image and the second image; and determining a score quantifying the quality of the registration of the first image and the second image.
