List of parameters for the coder JPEG 2000 :
Date : June the 25th, 2003
Author : Yannick Verschueren
Contact : verschueren@tele.ucl.ac.be
- the option -help displays the readme.txt file on screen
- The markers COD and QCD are writed both of two in the main_header and never appear in the tile_header. The markers in the main header are : SOC SIZ COD QCD COM.
- This coder can encode mega image, a test was made on a 24000x24000 pixels color image. You need enough disk space memory (twice the original) to encode the image. (i.e. for a 1.5 Gb image you need a minimum of 3Gb of disk memory)
REMARKS :
---------
* the value of rate enter in the code line is the compression factor !
exemple :
-r 20,10,1 means quality 1 : compress 20x, quality 2 : compress 10x and quality 3 : compress 1x = lossless
* The number of resolution can be modified by the program in view to respect profile-0 conditions (Taubman, Marcelin (2002), "JPEG2000, image compression fundamentals, standards and practice", p700)
By default :
------------
* lossless
* 1 tile
* size of precinct 2^15 x 2^15 (means 1 precinct)
* size of code-block 64 x 64
* Number of resolution : 6
* No SOP marker in the codestream
* No EPH marker in the codestream
* No sub-sampling in x and y direction
* No mode switch activated
* progression order : LRCP
* No index file
* No ROI upshifted
* No offset of the origin of the image
* No offset of the origin of the tiles
* Reversible DWT 5-3
Parameters :
------------
-i : source file (-i source.pnm also *.pgm, *.ppm) "required"
-o : destination file (-o dest.j2k) "required"
-r : different rates (-r 20,10,5) "optional"
-n : Number of resolution (-n 3) "optional"
-b : size of code block (-b 32,32) "optional"
-c : size of precinct (-c 128,128) "optional"
-t : size of tile (-t 512,512) "optional"
-p : progression order (-p LRCP) [LRCP, RLCP, RPCL, PCRL, CPRL] "optional"
-s : subsampling factor (-s 2,2) [-s X,Y] "optional"
-SOP : write SOP marker before each packet "optional"
-EPH : write EPH marker after each header packet "optional"
-M : mode switch (-M 3) [1= BYPASS(LAZY) 2=RESET 4=RESTART(TERMALL) 8=VSC 16=ERTERM(SEGTERM) 32=SEGMARK(SEGSYM)] "optional"
for several mode switch you have to add the value of each mode you want
ex : RESTART(4) + RESET(2) + SEGMARK(32) = -M 38
-x : Create an index file *.Idx (-x index_name.Idx) "optional"
-ROI:c=%d,U=%d : quantization indices upshifted for component c=%d [%d = 0,1,2]
with a value of U=%d [0 <= %d <= 37] (i.e. -ROI:c=0,U=25) "optional"
-d : offset of the origin of the image (-d 150,300) "optional"
-T : offset of the origin of the tiles (-T 100,75) "optional"
-I : Use the irreversible DWT 9-7 (-I) "optional"
IMPORTANT :
-----------
* subsampling bigger than 2 can produce error
The index file respect the structure below :
---------------------------------------------
Image_height Image_width
progression order
Tiles_size_X Tiles_size_Y
Components_nb
Layers_nb
decomposition_levels
Precincts_size_X Precincts_size_Y
Main_header_end_position
Codestream_size
Tile0 start_pos end_Theader end_pos
Tile1 " " "
...
TileN " " "
Tpacket_0 Tile layer res. comp. prec. start_pos end_pos
...
Tpacket_M " " " " " " "

* NOTE:
* This is a modified version of the openjpeg dwt.c file.
* Average speed improvement compared to the original file (measured on
* my own machine, a P4 running at 3.0 GHz):
* 5x3 wavelets about 2 times faster
* 9x7 wavelets about 3 times faster
* for both, encoding and decoding.
*
* The better performance is caused by doing the 1-dimensional DWT
* within a temporary buffer where the data can be accessed sequential
* for both directions, horizontal and vertical. The 2d vertical DWT was
* the major bottleneck in the former version.
*
* I have also removed the "Add Patrick" part because it is not longer
* needed.

Preliminary DTD for Open JPEG "mj2_to_metadata" function.
Last revised: April 20, 2005
Author: Glenn Pearson, at U.S. National Library of Medicine.
See mj2_to_metadata.c regarding copyright, license, disclaimer status.
While the vocabulary of this DTD is based on the relevant portions of the
ISO/IEC JPEG 200 standard, the detailed representation is the author's own.
It is neither an ISO/IEC nor NLM official or consensus representation.
Furthermore, it deviates from a pure representation of the ISO/IEC standard
in these aspects:
- it is incomplete in a number of ways (which to some extent may be
addressed over time);
- it has extensions for "derived" data and "statistics";
- it is more flexible. That is, some elements are marked as optional
not because they are optional in an MJ2 file, but because reporting
of them is optional based on current or projected mj2_to_metadata
command-line flags.
