Abstract
A computer-implemented method that includes: accessing data encoding a fingerprint slap scan image, the fingerprint slap scan image including fingerprints of a number of fingers from a subject's hand; performing a radon transform of the fingerprint slap scan image to generate a sinogram, the sinogram represented on a grid having a lateral span axis and a projection angle axis; automatically identifying patterns of segments on the sinogram as finger lines, each finger lines corresponding to a particular finger present on the fingerprint slap scan image; and based on identified finger lines on the sinogram, automatically determining whether one or more fingers are missing on the fingerprint slap scan image.
