Rational polynomial functions have many applications, such as filter design, system theory, and digital image processing. In particular, rational polynomial functions provide the most common way of representing the z-transform. A rational polynomial function takes the form of the division of two polynomials...  3, record 1, English, - rational%20polynomial%20function

Wireless Digital Video. From a computer-engineering standpoint, this research combines elements of image processing, data compression, and networking theory into the development of a robust system capable of transporting video-like image sequences over relatively low speed links that are susceptible to interference.  2, record 2, English, - wireless%20digital%20video

Fractal Image Compression is about the mathematical ideas that lie behind the photographs and other pictures on Encarta. They are all fractals! They are stored as highly compressed data files produced using fractal image compression. Fractal image compression involves three basic mathematical modeling problems. The required models are [:] a mathematical model for real world image, a model for approximating model images by means of resolution independent image approximants, which must be described by finite data strings, and a computationally tractable model for the sources of the data strings, to enable the application of information theory to provide efficient representation of the image approximants.  2, record 3, English, - fractal%20image%20compression

Suppression automatique de tous les octets superflus dans une image numérisée, à l'aide d'algorithmes fractals qui combinent la théorie de l'information et la perception visuelle pour décrire des formes compliquées au moyen de formules très simples. Le stockage de ces formules permet la reconstruction par itération des images de départ.  1, record 3, French, - compression%20fractale%20d%27images

Les images codées en formules fractales ont un taux de compression de 70:1 et sont reconstruites sans aucune détérioration. Or, au-delà d'un taux de l0:1, les techniques habituelles risquent fort de nuire à la reconstruction de l'image. Technique déjà appliquée avec succès à la compression d'images sismiques en utilisant un algorithme fractal inspiré de la courbe de Peano. Voir les travaux récents de M.

In theory, one might expect that stereoscopic vision would be a desirable feature in order to give depth to the intensified image, but in practice this is not so : stereo can be traded for reduced weight and cost.  1, record 4, English, - intensified%20image

Les conducteurs y gagneront en vision périphérique mais au prix d'une plus grande fatigue. En théorie, on pourrait croire que la vision stéréoscopique est souhaitable de façon à donner du relief à l'image intensifiée mais l'expérience montre qu'il n'en est rien.  1, record 4, French, - image%20intensifi%C3%A9e
