We are dealing with large JPEG2000 satellite images which usually are **tiled** with **1024X1024** or **2048X2048** tile sizes (e.g. SPOT6 images). After some testing, we measured an improvement when the block size is equal to a tile size. To deal with too large tiles (or no tiles at all), it is necessary to keep an upper limit, say 2048 X 2048.
