This paper introduces a new method to solve the problem of matching correspondent feature points across two images containing a moving rigid object. Two successive time-varying images are used. Edge points are first extracted using a 3x3 Laplacian mask. Walsh transformation is then applied to the feature points in both images. The choice of Walsh transformation in contrast to other orthogonal t...

In this paper, we propose a secure route optimization mechanism for network mobility management. By means of the mechanism, the Mobile Router securely proxies the care-of address for the Mobile Network Node. The Mobile Router sends a Binding Update directly to the Correspondent Node on behalf of the Mobile Network Node. The Binding Update binds the Mobile Network Node’s original address to the ...

We study the behavior of bound energy levels for the case of two classical interacting fields φ and χ in a finite domain (box) in (1 + 1) dimension on which we impose Dirichlet boundary conditions (DBC). The total Lagrangian contain a λ 4 φ self-interaction and an interaction term given by gφχ. We calculate the energy eigenfunctions and its correspondent eigenvalues and study their dependence o...

RÉSUMÉ. Cet article se propose de comparer les structures de discours proposées en RST, SDRT et dans les DAG de dépendances prolongeant le niveau sémantique de MTT pour le discours. Le point central est le suivant : est-ce que ces formalismes permettent de représenter toutes les structures de discours qui correspondent à des discours bien construits et excluent toutes celles qui ne corresponden...

In this article, a new method for camera self-calibration is presented. A correspondent matrix can be built by matching the corresponding vanishing points between two images and the proposed method must use at least two of these matrices for calibration. The images are all taken from different orientations in any locations for the same object in space. The vanishing points in the image are the ...

Nous considérons plusieurs processus ponctuels de Poisson indépendants sur Rd, chacun d’une couleur différente et possiblement intensité différente, nous supposons donné un ensemble type familles, étant multi-ensemble couleurs comme rouge-bleu ou rouge-rouge-bleu. étudions les stratégies invariantes par translations pour partitionner points en familles types autorisés. Ceci généralise d’apparie...
