Abstract
This article presents an implementation of the local image enhancement 
technique proposed in [J.L. Lisani, Adaptive local image enhancement 
based on logarithmic mappings, IEEE International Conference on Image 
Processing (ICIP), 2018]. The technique is based on a logarithmic 
mapping function that is adapted to the luminance characteristics of the 
neighborhood of each pixel. The method permits to simultaneously 
increase the luminance in dark regions and decrease it in bright 
regions. Variants of the originally published method are discussed in 
terms of contrast enhancement and creation of halo artifacts.
