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
|
|
||||||
|
|
||||||
