Claim One:
1. A method of processing images to determine at least one signature of a film, characterized in that it includes the following steps: selecting chronologically a series of images (I 11 , I 12 ,. .. I PN ) from said film; evaluating shifts relating to at least one descriptor corresponding to a physical property between consecutive images in order to obtain primary visual shifts; calculating differences between said primary visual shifts to determine secondary visual shifts (ES 1,1,1 ,. .. , ES 1,1,N-2 ); calculating differences between said secondary visual shifts to determine tertiary visual shifts (ET 1,1,1 ,. .. , ET 1,3,N-3 ); and determining a mean value and a standard deviation of the primary, secondary, and tertiary visual shifts to obtain the signature (S 1 ) of the film.
