1. Method for coding an image within a sequence of images, comprising a step for 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, also comprising a step of entropy coding of at least one of the signals of high spatial frequency relating to the current image by taking a temporal context based on the estimation of a movement into account, one of the parameters exploited for the calculation of the temporal context being the parity relating to a component of the motion vector.
