GEDAI🔗

GEDAI denoising in python🔗

GEDAI_logo

For more details about the GEDAI algorithm, please refer to the MATLAB implementation.

Installation🔗

Standard (Lightweight NumPy)🔗

For standard CPU usage without heavy dependencies (~50 MB download):

pip install gedai

Accelerated (PyTorch Engine)🔗

For accelerated performance (up to 2.2x faster execution via vectorized PyTorch linear algebra):

pip install "gedai[torch]"

Note: gedai defaults to engine="auto". If PyTorch is installed, acceleration is used automatically; otherwise, it falls back cleanly to NumPy.

Tip for CPU-only systems: If you only need CPU acceleration on Windows/Linux and want to avoid downloading large GPU/CUDA binaries (~2 GB), install the lightweight PyTorch CPU wheel:
pip install torch --index-url https://download.pytorch.org/whl/cpu
pip install gedai
