Abstract
In this paper, we proposed a method to enhance global contrast of an image based on average luminance with weighted histogram equalization (ALWHE) for low dynamic range images (LDRI). Automation of parameter selection can easily be done by iteratively using the proposed method. The purposed method overcomes the disadvantage of HE like luminance shifting and washed-out looking. We present experimental results to compare results of contrast enhancement with other methods.
