Abstract :
In this paper, we propose a scatter-glare correction method based on thickness estimation and digital filtration. The method is an improvement of the scatter-glare correction method proposed by Ersahin, et al The method estimates scatter glare fraction in two steps. The first step is to assign an equivalent Lucite thickness to every pixel in the image, and the second step is to estimate the scatter-glare fraction from the thickness information. Experiments show that this method can well estimate the scatter-glare fraction in a wide range of thicknesses, and a higher accuracy for scatter-glare estimation can be obtained by this method compared with Ersahin´s method.
