In a 8-bit image the maximum entropy achieved can by 8 bits/pixel_value this occurs when the histogram is flat. In the Table 4 the entropy of Lena image Fig. 6(a) and medical image Fig. 7(a) and their cipher image entropy of Figs. 6(b) and 7(b) respectively is shown. The comparison analysis is calculated with [1] and [3].Table 4.Entropy of original and encrypted images
