US Patent 7940270 Computer processing of multi-dimensional data

The present invention relates to a solution for processing source data into target data. A rim distance (δ4) between the block sample boundary (βSB) and the block edge (b4) is relatively short for a comparatively high resolution level (r3), and the rim distance (δ1) is relatively long for a comparatively low resolution level (rO). In connection with the production of the target data (DT) at least one interpolation parameter (ρS1, e(PS1)) is determined for at least one interpolated sample between a first block (B2) neighboring a second block (B3) at least based on a first rim distance (δ2) of the first block (B2) and a second rim distance (δ3) of the second block (B3).
