A METHOD FOR ENCODING IMAGES IN A BLOCK-BASED MANNER EMPLOYING BLOCK SPATIAL PREDICTION

摘要

A method for encoding a digital image in a block-based manner, the method comprises performing a prediction for a block to be coded with respect to a reference block, wherein displacement between the block to be coded and the reference block is represented by a horizontal displacement and a vertical displacement; defining an ordered list of each possible horizontal and vertical displacements in a rank order; and providing a signal representative of the rank of the horizontal displacement and the vertical displacement in the ordered list.
