Description
An important subproblem in image analysis is the comparison of different images, which usually involves the calculation of inner products between pairs of images. In this poster we provide a new method for computing such inner products for arbitrary rotations and a user-specified range of translations. Our method takes advantage of the Fourier–Bessel basis to efficiently handle rotations, while at the same time using an optimal factorization of the translation kernel. For standard applications in cryomicroscopy our method is roughly an order of magnitude faster than the state of the art.
