Abstract

The present disclosure relates to an apparatus and a method for providing a plurality of motion vectors related to an image coded in a bitstream. The method includes obtaining a set of sample positions within the image, obtaining respective motion vectors associated with the set of sample positions, deriving an additional motion vector based on information coded in the bitstream, determining an additional sample position located within a triangle, which is formed by three sample positions of the set of sample positions, based on the respective motion vectors associated with the three sample positions, the triangle not including the rest of the sample positions of the set of sample positions, adding the additional sample position to the set of sample positions, and associating the derived additional motion vector with the additional sample position.
