Abstract
Slices of image data are collected and frames of image data within the slices are compared and used to determine the overlap between slices so that full images may be reconstructed. Slice and frame image correlation methods are also used to compensate for image stretch. Slice and frame correlation techniques are disclosed that may be used to determine swipe start, swipe stop and swipe too fast conditions as well as anti-spoof techniques.
