Method for determining the quality of digital images. An anisotropic measure is used as a metric to assess the quality of images. The method is based on measuring the variance of the expected entropy of a given image upon a set of predefined directions. Directional selectivity is attained by using an oriented 1-D pseudo-Wigner distribution.
