Methods and apparatus are provided for decoding video signals using example-based data pruning for improved video compression efficiency. An apparatus for recovering a pruned version of a picture in a video sequence includes a divider for dividing the pruned version of the picture into a plurality of non-overlapping blocks, a metadata decoder for decoding metadata for use in recovering the pruned version of the picture, and a patch library creator for creating a patch library from a reconstructed version of the picture. The patch library includes a plurality of high-resolution replacement patches for replacing the one or more pruned blocks during a recovery of the pruned version of the picture. The apparatus further includes a search and replacement device for performing a searching process using the metadata to find a corresponding patch for a respective one of the one or more pruned blocks from among the plurality of non-overlapping blocks and replace the respective one of the one or more pruned blocks with the corresponding patch. |
