MERGING AND SPLITTING DATA BLOCKS

摘要

A first set of discrete cosine transform (DCT) blocks is obtained. Each DCT block from the first set of DCT blocks has a first block size. When performing a split operation on the first set of DCT blocks, a filter is applied to the first set of DCT blocks. A second set of data blocks is generated based on the first set of DC blocks using a transform function. Each block in the second set of data blocks has a second block size. When performing a merge operation, the filter is applied to the second set of data blocks.

1. A method, comprising:
obtaining a first set of discrete cosine transform (DCT) blocks, each DCT block from the first set of DCT blocks having a first block size; determining whether to perform a merge operation or a split operation on the first set of DCT blocks; applying a filter to the first set of DCT blocks when performing the split operation; generating, using a transform function, a second set of data blocks based on the first set of DCT blocks, each data block from the second set of data blocks having a second block size; and applying the filter to the second set of data blocks when preforming the merge operation.
