Munker–White-Like Illusions without T-Junctions

Some interpretations of the Munker–White illusion were evaluated by designing new versions of this illusion devoid of T-junctions (Munker–White-like images). The magnitudes of both Munker–White and Munker–White-like illusions were then quantified by using a brightness-matching technique. The results showed the effect to persist in all proposed versions. Since the illusion still remains despite the absence of explicit T-junctions and any explanation considering transparency, mechanisms other than those proposed by these interpretations must be responsible.
