Local contrast enhancement (LCE) gives a more lively look to an image or video. With a larger difference of a pixel's luma value from its local mean, the eye needs less time to adjust to that local region for a better contrast sensitivity. Since the human eye is trained and conditioned to recognize a natural looking face, the faces in a locally enhanced image may look unnatural even though other parts of the enhanced image is visually more attractive than the original image. To solve this

Experiment results show that SALSA produces natural looking face and non-facial skin regions in the locally enhanced image.
