Preparation: Data and Base Codecs

Data

# download ARAD 1K dataset from https://github.com/boazarad/ARAD_1K
ln -s ARAD_1K_HSI_abs_path data/ARAD

data/ARAD/ARAD_1K_09xx.tif

Base Codecs

See Codecs.py for HEVC and VVC, etc.

Encode

python encode.py -i data/ARAD/ARAD_1K_0901.tif -codec JPEG2000 -Q 6

Decode

python decode.py -i outputs/ARAD_1K_0901_JPEG2000_s1.0_Q6.0_D0_prec32/ARAD_1K_0901.bin -org data/ARAD/ARAD_1K_0901.tif

Experiments

python Codecs.py # run SOTA codecs (including preprocessing of the datasets)
python run_ARAD.py # run LoCaCF-HSIC: SOTA + LoCaCF
# Code of LineRWKV: https://github.com/diegovalsesia/linerwkv
# We provide the results of LineRWKV (+ LoCaCF) in SOTA_results
python BD_metrics.py # BD metrics and R-D curves

TODO

• AVIF (compression of 8/10/12-bits grayscale images), etc. https://gdal.org/en/latest/drivers/raster/avif.html
• HEIF with GDAL, https://gdal.org/en/latest/drivers/raster/heif.html
