Patent ID: 11166019

Abstract:
The disclosure relates to a method for processing the noise of a stream comprising a series of images, comprising spatial filtering of a current image In in order to obtain a spatially filtered image Sn; determining a motion vector for each block B of pixels of the image Sn, from a single image Sn-1; calculating a confidence index αn[B] for each block B of image In, from the motion vector determined for B; constructing a temporal filter from the calculated confidence indices αn[B] and applying the temporal filter to the current image In in order to obtain a temporally filtered image Tn; spatial filtering of the current image In in order to obtain a spatially filtered image Dn where Dn can be equal to Sn, and obtaining a temporally and spatially filtered image Rn by applying a function combining image Tn and image Dn.
