Conditional Replenishment and Motion Compensation based on JPEG2000.
This is a work in progress.
0) Include the Kakadu SDK in the project
Kakadu SDK is needed in order to compile some tools used in this project.
KaKadu SDK has to be located in the next directory:
1) Compile Kakadu
Example of how to compile Kakadu (version: v6_4_1-00305L) on Linux:
$ /vagrant/src/Kakadu/v6_4_1-00305L/make/make -f Makefile-Linux-x86-64-gcc
2) Set the LD_LIBRARY_PATH variable
$ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/vagrant/src/Kakadu/v6_4_1-00305L/lib/Linux-x86-64-gcc
3) Set the PATH variable
$ export PATH=$PATH:/vagrant/src/Kakadu/v6_4_1-00305L/bin/Linux-x86-64-gcc
4) Set the CR_MC_J2K_HOME global variable
$ export CR_MC_J2K_HOME=/vagrant
5) Compile all the tools of the project
You can compile all the tools of the project using the Makefile located in
$ cd $CR_MC_J2K_HOME/make/ $ make
How to use
0) Add the directory with the source images
The source images (e.g. PGM) have to be located in the next directory:
In the directory
cr_mc_j2k/data/scripts there are some scripts that can be
useful in order to process the source images and prepare them for the
The compressed JPEG2000 images (J2C) have to be located in the directory:
Clean old and temp files:
1) Compress the sequence to JPEG2000
2) Create a config file for the sequence
Create a configuration file that includes all the parameters for running scripts and store it in the directory:
3) Update the config file
Once you have created the file you have to update the
$CR_MC_J2K_HOME/config/cr_mc_config.sh file to specify which configuration
file have to be used.
... source $CR_MC_J2K_HOME/config/sequences/speedway_layers-8_levels-2_precincts-64-32-16_blk-16.cfg ...
4) Create the Kanpsack files (JSON) (Only for knapsack mode)
Example of how to create the Knapsack files for a sequence of images composed by 900 frames (from frame 1 until frame 900):
$ $CR_MC_J2K_HOME/knapsack/tools/create_all_kanpsack_files/create_all_knapsack_files.sh 1 900
Note that you don't have to start in the frame 1, you can specify the number of the first frame where you can to start.
5) Create temporary directories
$ $CR_MC_J2K_HOME/scripts$ ./create_temp_directories.sh
6) Run the scripts!
Use the scripts located in the
$CR_MC_J2K_HOME/scripts to perform a simulation.
You can use the following scripts:
This script removes temporary files from previous simulations.
$ $CR_MC_J2K_HOME/scripts$ ./sequential.sh 1 900 5000
$ $CR_MC_J2K_HOME/scripts$ ./evaluate_bitrates.sh
The results of the simulation created with this script will be stored in a directory that should be indicated in the
