Claim:
An image encoding method, characterised by the following steps: selecting two images, split by series of at least one image that has to be undersampled; coding the images delimiting said series of images through a first image encoding, optimizing significantly a photometric representation of an image said first image encoding implementing a transformation on image blocks and a temporal prediction by blocks; coding each image of the series of images through a second image encoding optimizing a representation of motion between at least two images, said second encoding taking into account of at least one of: a motion vector field calculated from an immediately preceding image encoded using said first encoding, a motion vector field calculated from an immediately subsequent image encoded using said first encoding, said second encoding relying on the implementation of a mesh made up of nodes enabling to detect non predictable areas in the series of images, such that: said mesh is used to process the non-predictable areas; said motion vector field is applied to said mesh and is used to determine a deduced motion vector field, related to an image encoded using said second encoding, so that each image is coded according to only one encoding mode, and wherein said second encoding implements a forward motion estimation, between an image I t1 and a subsequent image I t2 , and a step of motion compensation in which motion vectors obtained during said motion estimation and not leading to reversal are weighted by a scalar k=m(t 1 +t 2 ), 0<k<1, in order to interpolate at least one image Im of the series, with m the index of the image in the series, m belonging to [t 1 , t 2 ], delivering an estimated image E 1 .
