The local Rényi entropy of a given image is calculated in four equally spaced orientations and used to determine the parameters of the von Mises distribution of the image entropy. The von Mises distribution’s concentration parameter κ and its fitness parameter φ appear as suitable for defining image quality assessment measures in some particular image distortions such as Gaussian blur or additive Gaussian noise. Details can be found in S. Gabarda and G. Cristóbal, “No-reference image quality assessment through the von Mises distribution”, J. Opt. Soc. Am. A, Vol. 29, No. 10 / October 2012. /
