Title (EN) AUTOMATED NOISE ATTENUATION IN FREQUENCY DOMAINS
(FR) ATTÉNUATION DE BRUIT AUTOMATISÉE DANS DES DOMAINES DE FRÉQUENCE
Abstract:
(EN) In some examples, an apparatus for automated removal of noise in a frequency domain receives an image captured by an image sensor, converts at least a portion of the image into a frequency domain image, identifies a position in the frequency domain image, the position indicating a boundary between target content in the frequency domain image and noise in the frequency domain image, and removes content in the frequency domain image outside the boundary, to produce a noise-attenuated image.
(FR) La présente invention concerne, dans certains exemples, un appareil pour l'élimination automatisée du bruit dans un domaine de fréquence qui reçoit une image capturée par un capteur d'image, convertit au moins une partie de l'image en une image de domaine de fréquence, identifie une position dans l'image de domaine de fréquence, la position indiquant une limite entre un contenu cible dans l'image de domaine de fréquence et le bruit dans l'image de domaine de fréquence, et élimine le contenu dans l'image de domaine de fréquence à l'extérieur de la limite, pour produire une image à bruit atténué.
