Field Detail

zSize

private int zSize

Definition in SIZParameters.zSize.

ySize

private int ySize

Definition in SIZParameters.ySize

xSize

private int xSize

Definition in SIZParameters.xSize

WTLevels

private int[] WTLevels

Definition in CODParameters.WTLevels

blockWidths

private int[] blockWidths

Definition in CODParameters.blockWidths

blockHeights

private int[] blockHeights

Definition in CODParameters.blockHeights

precinctWidths

private int[][] precinctWidths

Definition in CODParameters.precinctWidths

precinctHeights

private int[][] precinctHeights

Definition in CODParameters.precinctHeights

blocksPerPrecinctWidths

private int[][] blocksPerPrecinctWidths

Number of blocks in each precinct for resolution level and component (width dimension). Index means [z][rLevel]. If the number of blocks does not fit with precincts, take upper left corner in the subband to start. For example, if a subband have 3x3 blocks:
-------------------
| 1 | 2 | 3 |
|-----------------|
| 4 | 5 | 6 |
|-----------------|
| 7 | 8 | 9 |
-------------------
and BDBlocksPerPrecinctWidths[z][rLevel]==2 then precincts will contain these blocks: {1,2,4,5},{3,6},{7,8},{9}.

Values greater than 1.

blocksPerPrecinctHeights

private int[][] blocksPerPrecinctHeights

Same as blocksPerPrecinctWidths but for precinct heights.

Values greater than 1.

imageStructure

private int[][][][][][] imageStructure

Is a multi-dimensional array with the image structure. Indices means:
z: image component
resolutionLevel: 0 is the LL subband, and 1, 2, ... represents next starting with the little one
precinct: precinct in the resolution level
subband: 0 - HL, 1 - LH, 2 - HH (ifresolutionLevel == 0 --> 0 - LL)
yBlock: block row in the subband
xBlock: block column in the subband
