A new Retinex-based Squeeze and Excitation Network with Dark Region Detection (RSEND) is proposed for efficient low light image enhancement.
RSEND divides the low-light image into the illumination map and reflectance map, then captures important details in the illumination map for light enhancement.
The framework utilizes Squeeze and Excitation network to better capture details and performs well in complicated datasets like LOL-v2.
RSEND outperforms other CNN-based models and achieves significant improvement in peak signal-to-noise ratio (PSNR) in different datasets.
