Abstract
The invention relates to a method for predicting a pixel block of an image using a weighted sum of pixel blocks belonging to patches of a dictionary from a set of candidate patches, each patch being formed of a pixel block of an image and a causal neighborhood of this pixel block. The method is wherein a subset of candidate patches is obtained from the set of candidate patches and the dictionary is formed of a patch of the subset of candidate patches, called the first patch, and at least one other patch of said set of candidate patches, called the second patch.
