An Enhancement Algorithm for Non-uniform illumination Image based on two Homomorphic Filters
Ruipeng Luan · 2016
To solve the non-uniform illumination problem of digital images, an enhancement algorithm based on segmenting non-uniform illumination image into two sub images and filtering separately is proposed.The method how to segment the non-uniform illumination image into two sub images and fix on the cut-off frequency of homomorphic filter is studied.The experiment shows image enhancement effect of the proposed algorithm in this paper.
