1. A method for coding an image within a sequence of images, comprising spatial analysis of a current image in order to deliver a signal of low spatial frequency and signals of high spatial frequency and performing an estimation of a movement between a current time corresponding to the current image and a reference time corresponding to a reference image in order to supply a motion vector, and contextual entropy coding of at least one of the signals of high spatial frequency relating to the current image using table of probabilities defined by a temporal context based on the estimation of a movement, one parameter exploited for a calculation of the temporal context being a parity relating to a component of the motion vector.
