1. A method for the processing of the images of an original batch of N images having at least two spatial dimensions, to remove the noise therefrom, the N images of this batch representing N states of a periodic phenomenon, wherein said method comprises the following steps: a 2D spatial analytic transform is carried out on the images of the original batch to obtain a batch of N transformed images, each transformed image comprising a real part and an imaginary part; the N transformed images are time filtered by combining each image element of these transformed images with corresponding image elements in the other transformed images in order to obtain a batch of filtered transformed images, and a reverse 2D spatial analytic transform is carried out on the images of the batch of filtered transformed images to obtain a batch of N original filtered images.
