Record number: 4, Textual support number: 1 CONT

La convolution est utilisée dans le traitement d'image et plus particulièrement dans les applications de vision assistée par ordinateur. Elle aboutit, par exemple, à un renforcement des contours, à un lissage ou encore à la disparition de points parasites. La convolution consiste alors à modifier, à l'aide d'un algorithme spécifique, les caractéristiques d'un pixel (élément de base d'une image) en s'appuyant sur les pixels voisins.  3, record 4, French, - convolution

El tratamiento de imágenes más empleado y conocido, es el tratamiento espacial también conocido como convolución. Las convoluciones discretas son muy usadas en el procesado de imagen para el suavizado de imágenes, el afilado de imágenes, detección de bordes, y otros efectos. Mediante este proceso se calcula el valor de un determinado punto en función de su valor y del valor de los puntos que le rodean, aplicando una simple operación matemática en función de la cual se obtendrá un valor resultante para el punto en cuestión.  1, record 4, Spanish, - convoluci%C3%B3n

Modifying the geometry of an image (which may be from either a remotely sensed or map data source) [that] usually involves rectification and/or registration.  3, record 5, English, - resampling

Record number: 5, Textual support number: 1 CONT

Overview of resampling methods. From the perspective of space, a satellite camera or sensor takes images that provide unique Earth information at scales ranging from very small to very large. To better understand an image, its shape, scale and perspective often are changed by rectification, orthorectification or map projection to relate it to real world coordinates. During that process, however, gaps between pixels may form, requiring that images be resampled to fill in those missing pixels. There are basically 3 methods of resampling : nearest neighbor, bilinear interpolation and cubic convolution.  4, record 5, English, - resampling

Une fois déterminé le modèle mathématique permettant de passer d'un système de coordonnées à un autre, il faut encore calculer la valeur des pixels dans l'image redressée : c'est l'étape de rééchantillonnage. On a généralement le choix entre trois méthodes : [la] méthode du plus proche voisin (valeur de 1 pixel) [;] l'interpolation bilinéaire (valeur pondérée de 4 pixels) [;] la convolution cubique (valeur pondérée de 16 pixels).  3, record 5, French, - r%C3%A9%C3%A9chantillonnage
