Abstract

Provided is a method for analyzing image slices. The method includes transforming a first slice and a second slice to frequency domain and determining shift data between the first slice and the second slice from only the phase component of the transformed first and second slices.

Description

technical field [0001] The present invention relates to image alignment. More specifically, the present invention relates to the alignment of partial images produced by swipe biometric sensing devices. Background technique [0002] In the field of biometric image analysis, conventional techniques sample an image, such as a fingerprint, as it is moved or touched across a sensing mechanism. This sensing mechanism (which could be a fingerprint sensor) captures a partial image of the finger during a single tap. This single tap produces data sets at different times and in different coordinate systems. Computer vision techniques can then be used to reconstruct an image about the entire fingerprint by sampling these data sets and combining partial images to form a full image of the fingerprint. [0003] Those skilled in the art know that the process of transforming these different data sets into one coordinate system is image registration. Registration is necessary in order to ...
