We discuss a critical point of the paper. It is shown on the one hand that the author of this paper has mistaken the change of spectral content with the change in spatial resolution, and on the other hand, that the protocol used to establish the advantages of his smoothing filter-based intensity modulation (SFIM) technique over other methods is not appropriate at all. Though the SFIM technique has its merits, the article does not demonstrate its expected qualities.
