This article presents an innovative technique for solving the problem of finding the core within a fingerprint. The Radon transform and a tree clustering algorithm were key to locating the coordinates of the core. Binarization and high-pass filtering processes to improve the contrast in fingerprints are proposed. The core of a fingerprint is located in the(More)
This paper describes a new implementation of a mixture of techniques not used before for fingerprint recognition. The implementation consists of three stages: the location of the core, which is done through Radon transformation, the extraction of features (out of which a square fingerprint is produced with the core, and the center of the mass is obtained(More)
In this paper we present the use of Kohonen's Neural Network (or Self-Organizing Map-SOM) in an Automatic Speech Recognition (ASR) for isolated words in Spanish language with Mexican accent for a single speaker, the words that used indicated directionality, this application could be used in an automatic wheelchair. The corpus of this application uses four(More)
