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.

rad2deg is a MATLAB function

Abhishek Dubey

you forgot to include rad2deg function

When I read the lena.png to variable X, I run [Qg,Qch]=blindimagequality(X).
Then,' Qg =0.0038' is return.
Is it right. If some is wrong, How can I run this program.


Where do I get the paper from?
