Abstract

An adaptive correction algorithm for non-uniform illumination images is proposed, which can eliminate the impact of non-uniform illumination on imaging results. Firstly, the illumination component is extracted by the fast guided image filter based on the luminance-reflection imaging model. In succession, an improved two-dimentional Gamma function dynamically adjusted by the local distribution characteristics of illumination is constructed, which can increase the intensity value at the low-level illumination regions and vice versa at the high-level illumination regions in the luminance domain. Finally, the non-uniform illumination image is adjusted adaptively by the proposed algorithm. Experimental results of different imaging scenarios show that the proposed algorithm can reduce the impact caused by non-uniform illumination and enhance the quality of the images.
