filtre anti-crénelage ou filtre de lissage Explanation: This expression seems to be used with graphics, where it reduces the blur on computer images. So at first, I didn't really see what it had to do with a propeller balancing equipment. But it also comes into effect to counteract motion blur, so maybe it is part of the balancing equipment as it removes the blur in the motion of the propeller as the sensor tries to see any out-of-balance motion. Does that make sense? "Anti crénelage (anti-aliasing) : C'est un filtrage qui corrige les effets visuels indésirables (moirage, apparition de formes imprévues, ...) provoqués par la superposition d'objets graphiques de résolutions différentes. La plupart des logiciels de dessin possèdent une fonction anti-aliasing, certaines cartes 3D réalisent ce filtrage en temps réel dans les jeux." "LISSAGE (anti-aliasing) Adoucissement ou suppression des défauts d'aliasing (notamment l'effet de crénelage) par filtrage ou autres techniques." "crénelage n. m. <GRAPH> Effet très moche apparaissant sur les bords des éléments d'une image, dû à l'aspect discret (non continu) des données numérisées. Particulièrement disgracieux et indésirable. On applique alors un anti-aliasing pour le faire disparaître." "anticrénelage n. m. <GRAPH> Version française d'anti-aliasing. On rencontre bien plus souvent la version anglaise Reference: http://www.fulmedico.org/problem/dico/definitions/anti_alias... Reference: http://www.titan.be/titan.pages/glossair/l/lissage.htm |

filtre anti-aliasing Explanation: Just like Daupihne, I too found references principally to the types of context cited in her answer. My initial researches brought me onto the Kodak site : In digital imagery, this was explained as being information, images and colours which enter into an image although these were not part of the original scene. Filters are used to get rid of these unwanted "aliases". (www.kodak.fr/global/en/professional/products/cameras/antiAl... Also, with regard to noise, to remove frequencies above 20kHz from signals so as they are not aliased on the samlping - filters used to filter ou HF noise from external sources. (www.ph.ed.ac.uk/-dbs/thesis/mode31.html I agree with Dauphine's analysis that it is clearly a terms use din many contexts when unwanted and unsollicited elements appear, be it in terms of sound, images or whatever.(see the Barco site for cinema projectors too) Likewise, I think it is clear that the English term can be used in French too; This was confirmed by a cameraman client who confirms using it in lots of digital imagery and other contexts. Good luck. Nikki In terms of noise, thes filters are used see webrefs in body of explanation |
