A fuzzy approach for segmentation of touching characters
Giuseppe Airò Farulla, Nadir Murru, Rosaria Rossini
The problem of correctly segmenting touching characters is an hard task to solve and it is of major relevance in pattern recognition. In the recent years, many methods and algorith…
Artificial neural networks and fuzzy logic for recognizing alphabet characters and mathematical symbols
Giuseppe Airò Farulla, Tiziana Armano, Anna Capietto +2
Optical Character Recognition software (OCR) are important tools for obtaining accessible texts. We propose the use of artificial neural networks (ANN) in order to develop pattern…
On the k-regularity of the k-adic valuation of Lucas sequences
Nadir Murru, Carlo Sanna
For integers and , let denotes the greatest nonnegative integer such that divides . Moreover, let be a nondegenerate Lucas sequence…
The Biharmonic mean
Marco Abrate, Stefano Barbero, Umberto Cerruti +1
We briefly describe some well-known means and their properties, focusing on the relationship with integer sequences. In particular, the harmonic numbers, deriving from the harmonic…
