Opentestbench : an open-source framework to assess the performances of image compression schemes Copyright (C) 2015 intoPIX s.a. , Sébastien Lugan Copyright (C) 2017 Universite Catholique de Louvain, Alexandre Willème Opentestbench is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.

See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program. If not, see . For any question please contact : Alexandre Willème (alexandre.willeme@uclouvain.be) ------------------------------------ IMPORTANT NOTES : - the boost library must be installed manually (for instance http://sourceforge.net/projects/boost/files/boost/1.60.0/boost_1_60_0.tar.gz/download) in order to make vc2-reference work - opentestbench works only on Linux. - If the target directory for decompressed frames already contain frames of the sequence under test, the compression/decompression will not happen ------------------------------------ Experiment types: - singlegen : simple encoding/decoding of a set of pictures and PSNR computations wrt the original picture (example runSG.sh) - multigen : several consecutive encoding/decoding of a set of pictures and PSNR computations after each iteration wrt the original picture (example runMG.sh) - errortest (to be fixed) : a single bit-flip at a random position is inserted in the bitstream before decoding and PSNR computations wrt the original picture - overlay test (to be fixed) - multi-generation test with pixel shift between each generation (to be fixed) - VDP assessment (to be fixed) ------------------------------------ Currently supported codecs : - JP2K ULL (Kakadu) - JP2K ULLC (Kakadu) - VC-2 LD (vc2-reference) - VC-2 HQCBR (vc2-reference) - JPEG (with pseudo-CBR mode) (jpeg-xt reference software) - JPEG LS (with pseudo-CBR mode) (jpeg-xt reference software) - DSC - HEVC HM (with pseudo-CBR mode) - HEVC HM Screen Content Coding extension (with pseudo-CBR mode) - XSM (version 1.4) ------------------------------------ Currently supported image formats : - RGB 4:4:4 8b, 10b and 12b in PPM files - YCbCr 4:2:2 10b and 12b in RAW planar 16-bit little-endian files ----------------------------------- Instructions : - To install: 1. Go to the opentestbench folder. 2. If you have a version of DSC (e.g. DSC_model_201407151.zip) put the zip file in opentestbench/codecs/DSC 3. To be able to make vc2-reference work, libboost must be installed (http://www.boost.org/) 4. Run bash install.sh. - To add a new codec: 5. Modify the encapsulator benchmark/prototype/prototype.sh to add your encoder and decoder command lines for RGB 8b, 10b and 12b and YCbCr 4:2:2 10b and 12b 6. For example, look at benchmark/vc2ld/vc2ld.sh if you want to know how to do format conversion using difftest_ng 7. Do not hesitate to ask support if needed - To run compression-decompression and compute PSNR 8. Configure the experiment (see runSG.sh or runMG.sh for examples) 9. Run the experiment configuration file (e.g. bash runSG.sh) 10. Observe the results in the "results" folder. - To generate rate-distorsion curves using Matlab: 11. Graphs can be generated automatically using matlab by modifying and running run_graphics.sh (work in progress) 12. Observe the results in the "graphics" folder. - To generate flicker sequences: 13. Flicker sequences (in the sense of the JPEG XS CfP assessment) can be generated (see run_subj_seqs.sh). This requires ffmpeg. 14. The results are available in the "preprocessed_material" folder ----------------------------------- Uninstall: 1. opentestbench installs all required software locally. Deleting the opentestbench/build folder undo the effect of install.sh -----------------------------------
