Halo Reduction in Display Systems through Smoothed Local Histogram Equalization and Human Visual System Modeling

Prasoon Ambalathankandy, Yafei Ou, Masayuki Ikebe

Abstract: 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.
