This corrigendum fixes incremental errors in specific visual secret sharing schemes, aiding researchers in the field.
The paper corrects previously reported contrast values for several visual secret sharing schemes, recalculating and presenting the accurate values to address errors cited by other researchers.
It has been observed that the contrast values for (2, 3) VSS scheme, (2, 4) VSS scheme, (3, 5) VSS scheme and (4, 5) VSS scheme claimed by Wu and Sun (2013) are found to be incorrect. Since the same values are cited and compared by many other researchers in their works, we have calculated and presented the correct values of contrast in this note.
