Information Hiding - Final Project
Real-world Perturbed Quantization

Setup

git clone --recurse-submodules git@github.com:TFILIPS/infohiding-project.git
cd jpeglib
python setup.py install
cd ../conseal
pip3 install .

Prepare Benchmark Data

cd experiments
python .\prepare_data.py \
  --workflow compression juniward naive islow \
  --quality_factors 75 95 \
  --alphas 0.0 0.1 0.2 0.3 0.4 0.5 0.6 \
  --cutoff_range 0 2500 --workers 8

Run Benchmark

cd experiments
python .\benchmark.py \
  --stego_methods juniward naive islow \
  --quality_factors 75 95 \
  --alphas 0.0 0.1 0.2 0.3 0.4 0.5 0.6

Notes:

• Tests and running ci pipeline are in my fork of conseal.
• jpeglib implementation was already usable, and I did not change anything, although ifast coefficient extraction is probably incorrect.
