This paper describes a new feature set for use in the recognition of on-line handwritten Devanagari script based on Fuzzy Directional Features. Experiments are conducted for the automatic recognition of isolated handwritten character primitives (sub-character units). Initially we describe the proposed feature set, called the Fuzzy Directional Features (FDF) and then show how these features can ...

In this paper we address the issue of recognizing Farsi handwritten words. Two types fo gradient features are extracted from a sliding vertical stripe which sweeps across a word image. These are directional and intensity gradient features. The feature vector extracted from each stripe is then coded using the Self Organizing Map (SOM). In this method each word is modeled using the discrete Hidde...

In this paper, we present a new approach for fingerprint classification based on Discrete Fourier Transform (DFT) and nonlinear discriminant analysis. Utilizing the Discrete Fourier Transform and directional filters, a reliable and efficient directional image is constructed from each fingerprint image, and then nonlinear discriminant analysis is applied to the constructed directional images, re...

Seismic coherence is widely used in seismic interpretation and reservoir characterization to highlight (with low values) faults and stratigraphic features from a seismic image. A coherence image can be computed from the eigenvalues of conventional structure tenors, which are outer products of gradients of a seismic image. I have developed a simple but effective method to improve such a coherenc...

L’extraction de motifs séquentiels est un domaine de la fouille de données permettant de rechercher des corrélations fréquentes entre des valeurs en prenant en compte leur chronologie d’apparition. Dans le contexte du panier de la ménagère, ce type de méthodes permet par exemple l’extraction de règles de la forme 〈(TV,DV D)(magneto numerique)〉, indiquant qu’un nombre suffisamment important (au ...

An Ad-hoc network is a dynamic network farmed on demand by a group of nodes without any pre-existing network infrastructure. Self configurability and easy deployment feature of the Mobile Ad-hoc network (MANET) resulted in numerous applications in modern era. An efficient and effective medium access control (MAC) protocol is essential in ad-hoc network for proper sharing of channel. The omnidir...
