Problems solved by technology

However, other classes of methods use an in-loop approach, which means that the encoder architecture must be modified to accommodate block removal
Therefore, other classes of methods are not strictly preprocessing-based methods because the encoder must be modified

Abstract

Method and apparatus are provided for recovering a pruned version of a picture in a video sequence is disclosed. An apparatus includes a pruned block identifier for identifying one or more pruned blocks in the pruned version of the picture. The apparatus further includes a metadata decoder for decoding metadata for recovering the pruned version of the picture. The metadata includes position information of the one or more replacement blocks. The apparatus also includes a block restorer for respectively generating one or more replacement blocks for the one or more pruned blocks.
