Abstract
SALAZAR COLORES, Sebastián et al. Dark Channel Applied for Reduction of the Effects of Non-uniform Illumination in Image Binarization. Comp. y Sist. [online]. 2019, vol.23, n.2, pp.409-416. Epub Mar 10, 2021. ISSN 2007-9737. https://doi.org/10.13053/cys-23-2-3202.
Non-uniform illumination is a common issue in images acquired in uncontrolled environments. Elimination or reduction of the non-uniform illumination problem is required in order to get an accurate image binarization. This paper introduces the combination of the dark channel and the atmospheric scattering model along with the k-means segmentation to reduce the effects of non-uniform illumination conditions in image binarization. The results show the effectiveness and robustness of this approach.
Keywords : Non-uniform illumination; uneven illumination; dark channel; binarization.
