Illumination compensation for face image using retinex method based on bilateral filtering
, 2010 Illumination variation is one of the critical factors affecting face recognition rate. In the paper, we propose a novel Retinex method based on bilateral filtering to compensate the illumination for face image.

Multi-channel low-light image enhancement method based on global robust Retinex model
Shenzhen Daxue xuebao. Ligong banIn response to the issues where existing illumination enhancement methods ignore the changes in hue and saturation under different lighting conditions, resulting in the loss of excessive detail information while suppressing noise, we propose a global ...
