Halo Reduction in Display Systems through Smoothed Local Histogram
  Equalization and Human Visual System Modeling
Prasoon Ambalathankandy Yafei Ou Masayuki Ikebe
Halo artifacts significantly impact display quality. We propose a method to
reduce halos in Local Histogram Equalization (LHE) algorithms by separately
addressing dark and light variants. This approach results in visually natural
images by exploring the relationship between lateral inhibition and halo
artifacts in the human visual system.
