An image-processing method for filtering light pollution appearing in a video image stream acquired by a video camera. The method includes, for a current image of the video image stream, the steps of subtracting the background represented in the current image in order to obtain the foreground of the current image, determining a brightening matrix, determining a compensating matrix by restricting the values of the pixels of the determined brightening matrix, segmenting the determined brightening matrix, determining a mask from the segmented brightening matrix, applying the mask to the determined compensating matrix in order to obtain a filtering matrix, and filtering the foreground of the current image by applying the filtering matrix in order to decrease the zones of light pollution in the images of the image stream.
