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 Iin order to obtain a spatially filtered image S; determining a motion vector for each block B of pixels of the image S, from a single image S; calculating a confidence index α[B] for each block B of image I, from the motion vector determined for B; constructing a temporal filter from the calculated confidence indices α[B] and applying the temporal filter to the current image Iin order to obtain a temporally filtered image T; spatial filtering of the current image Iin order to obtain a spatially filtered image Dwhere Dcan be equal to S, and obtaining a temporally and spatially filtered image Rby applying a function combining image Tand image D.
