Ring Line Mapping and Rotation Inertial for Fingerprint Identification

This study uses the r-theta transformation technique to map a fingerprint image to the straight-line signals. Subsequently, the “vector magnitude invariant transform” technique is applied to them to generate an invariant magnitude for person identification. This technique can solve the image rotation problem. Various vertical magnitude strips are generated to deal with the imageshifting problem. The algorithm developed in this study can precisely classify the fingerprint images.
