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 :

/* This program is an encoder/decoder for Reed-Solomon codes. Encoding is in
|
||||
systematic form, decoding via the Berlekamp iterative algorithm.
|
||||
In the present form , the constants mm, nn, tt, and kk=nn-2tt must be
|
||||
specified (the double letters are used simply to avoid clashes with
|
||||
other n,k,t used in other programs into which this was incorporated!)
|
||||
Also, the irreducible polynomial used to generate GF(2**mm) must also be
|
||||
entered -- these can be found in Lin and Costello, and also Clark and Cain.
|
||||
|
||||
The representation of the elements of GF(2**m) is either in index form,
|
||||
where the number is the power of the primitive element alpha, which is
|
||||
convenient for multiplication (add the powers modulo 2**m-1) or in
|
||||
polynomial form, where the bits represent the coefficients of the
|
||||
polynomial representation of the number, which is the most convenient form
|
||||
for addition. The two forms are swapped between via lookup tables.
|
||||
This leads to fairly messy looking expressions, but unfortunately, there
|
||||
is no easy alternative when working with Galois arithmetic.
|
||||
|
||||
The code is not written in the most elegant way, but to the best
|
||||
of my knowledge, (no absolute guarantees!), it works.
|
||||
However, when including it into a simulation program, you may want to do
|
||||
some conversion of global variables (used here because I am lazy!) to
|
||||
local variables where appropriate, and passing parameters (eg array
|
||||
addresses) to the functions may be a sensible move to reduce the number
|
||||
of global variables and thus decrease the chance of a bug being introduced.
|
||||
|
||||
This program does not handle erasures at present, but should not be hard
|
||||
to adapt to do this, as it is just an adjustment to the Berlekamp-Massey
|
||||
algorithm. It also does not attempt to decode past the BCH bound -- see
|
||||
Blahut "Theory and practice of error control codes" for how to do this.

26/6/91 Slight modifications to remove a compiler dependent bug which hadn't
|
||||
previously surfaced. A few extra comments added for clarity.
|
||||
Appears to all work fine, ready for posting to net!
