Abstract
A method is provided for predicting partitions of at least one group of pixels in an image to be coded, with respect to a group of reference pixels. Accordingly, the group of reference pixels is obtained by calculating a function characteristic of a predetermined mode of prediction, the reference pixels of the group obtained being variable from one partition to another.
