Tiling Artifacts and Region Of Interests


The left column contains results of regular compression at different bit rate with 5/3 reversible wavelet transform, no termination.

The right column contains images compressed under the same condition but with Region Of Interest specified for all samples at tile borders. The amount of shift is 10 bits and all samples in all subbands and resolutions are shifted if they are at the edge of a tile.
