6 April 1995 Neural network applied to direction map extraction in fingerprint images
Author Affiliations +
We present a new technique for extracting the direction map from fingerprints. The fingerprint image is first partitioned into small image blocks. Then, a set of parameters is extracted from each block and fed into a neural network that outputs the preferential direction for each block. The technique performed very well in operational conditions. It was developed to be employed in an Automatic Fingerprint Classification System.
