Fast Speed Low-light-Image-Enhancement

C++ implementation of two low-light image enhancement techniques

• A Bio-Inspired Multi-Exposure Fusion Framework for Low-light Image Enhancement
• LIME: Low-Light Image Enhancement via Illumination Map Estimation

Requirements

• cmake
• eigen-3.4
• OpenCV-3.X

Usage

c++
mkdir build
cmake -DFAST_SMOOTH=1 ..
make -j4
./main <input_image>

python
mkdir build
cmake -DFAST_SMOOTH=1 -DOPEN_PYBIND11=1 ..
make -j4
cd ..
python3 enhancement.py
