In digital imaging, the replacement of each pixel's gray level with a new value that has been adjusted to take into account the values of neighboring pixels [;] the degree to which the image is either smoothed or sharpened depends upon the specific calculations performed. 4, record 1, English, - convolution

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 1, 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 1, Spanish, - convoluci%C3%B3n
