Quality Index based on Local Variance (QILV)

Method to assess image quality based on local variance comparison with Golden Standard


Updated 31 May 2012

View License

QILV calculates a complementary method to assess image quality. It is based on the comparison of the local
variance distribution between an image and a Golden Standard. The index is
suited to better assess the non-stationarity of images, therefore
it explicitly focuses on the image structure.

The method is presented in

S. Aja-Fernández, R. San José Estépar, C. Alberola-López and C.F. Westin, "Image quality assessment based on local variance", EMBC 2006, New York, Sept. 2006.
