Erratum to “Optimizing Template for Lookup-Table Inverse Halftoning using Elitist Genetic Algorithm” [Jan 15 71-75]

In the above paper [ibid., vol. 22, no. 1, pp. 71-75, Jan. 2015], the top plots in Fig. 5 and Fig. 6 were erroneously labeled as "EM". In fact, those curves are actually the result of EGA with iterations 250, 500, 1000, 1500, 2000, 2500, 3000, 4000, 5000 respectively when L = 5, ..., 13. So "EM" of Fig. 5 amd Fig. 6 should have been labeled "EGA5". The corrected figures are shown here.
