ity measuring techniques. In this work, six color images are
used for testing: Lena, baboon, airplane, Barbara, peppers,
and sailboat, each of dimensions 256×256, are used as the
input for the proposed HDOE scheme. Fig. 10 shows the
input images and their histograms. For space limitation, most
of the results are reported for the double image of Lena and
Baboon.
A. Digital Encryption Results
1) Fusion Process Resul
The two-color images are applied to the fusion process, which
is the first step of DEsS, and the obtained images at different the generated chaotic image IC with the color fusion image IF
points are given in Fig. 11. Parts a and b of this figure show
the resultant high-bit and low-bit fusion images IF1 and IF2
for Leana and baboon. Parts (c and d) and (e and f) present the 4) Scrambling Image Results
results corresponding to (Barbara and airplane) and (sailboat
and peppers), respectively.

double-color image. (a), (c), and (e) high-bit image IF1 , (b),
(d), and (f) low-bit image IF2.
2) Color Images Combiner Results
The image combiner gathers the two fusion images Lena and
Baboon IF1 and IF2, each of size 256×256, one above the
other to produce a single image IF with a size of 512×256.
The same process is applied for other images. Fig. 12 shows
the results of the combiner output image.
3) Chaotic Fusion Image Results
Fig.13 displays the results describing the XOR operation of
to get a chaotic fusion image ICF .
A random scrambling operation is applied to the chaotic fusion
image ICF and the result is given in Fig. 14, corresponding to
the Lena-baboon case.
