PROBLEM TO BE SOLVED: To provide an inter-image prediction method and device, and a corresponding coding method and apparatus.SOLUTION: 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 (D) from a set of candidate patches (PS), each patch being formed of a pixel block of an image and a causal neighbourhood of this pixel block. In the method, a subset of candidate patches (SPS) is obtained from the set of candidate patches (PS) and the dictionary (D) is formed of a patch of the subset of candidate patches (SPS), called a first patch, and at least one other patch of the set of candidate patches (PS), called a second patch. |
