Abstract

The aim of the present comment is to point out wrong claim made by (Hosny, 2010) on the exact computation of radial moments. These errors are corrected in the comment. It is shown that the correct values of radial moments can be computed from numerical integration as exact computation of radial moments is not possible when the difference between moment order and repetition is odd.
