Abstract
A method for coding a current block using a parametric motion model whose parameters are defined from the motion data of the causal neighborhood is disclosed. Specifically, the method for coding the current block comprises the following steps: According to the invention, the parameters of the motion model are determined from the motion data associated with the causal neighborhood blocks of the current block. Therefore, they can be deducted from parts of images already coded and do not need to be incorporated in the image data stream.
