SPATIAL PREDICTION METHOD AND APPARATUS IN LAYERED VIDEO CODING

摘要

A spatial prediction method for coding a residual image in layered video coding. The spatial prediction method includes selecting at least one of a default mode, a horizontal mode and a vertical mode as a spatial prediction mode, taking into account an activity of at least one adjacent block located adjacent to a first block among blocks included in the residual image; and coding differences between pixels of the first block and pixels of a prediction bock constructed by one of the selected at least one or more spatial prediction modes. The at least one adjacent block includes a first adjacent block located on the left of the first block and a second adjacent block located on the top of the first block.
