In Table 1, the method-1[28] is for cartoon image which is given as
input and the features like ASM, entropy, co-relation, IDM are retrieved
values respectively 17059.140, 436.382, -161.766, and 271.589. For the
method-2[29] MRI image which is given as input and the same
feature’s values are 2.09822, 0.55052, 0.62423 and 0.03225 respectively.
Except for co-relation, all the other values of the MRI image are
smaller than cartoon image. In case of an Iris image method-3[3],
the corresponding feature’s values are 0.870, 2.411, 0.899 and 0.014.

Chart 1. Co-relation
In chart 1. Discuessed about co-relation features of
different images such as irish, MRI, cartoon and QR image. Cartoon image
acquire lower value than others Correlation will be low if an image
contains a less amount of linear structure. Other three images have most
probably equivalent values so they contain large amount of linear
structure.

Chart 2. Entropy
In chart 2. Discuessed about entropy features of
different images such as irish, MRI, cartoon and QR image. Here QR image
acquire higher value than others .Entropy is highest when all entries in
P[i,j] are of similar magnitude, and small when the entries in
P[i,j] are
unequal.

Chart 3. IDM
In chart 3. Discussed about IDM features of different
images such as irish, MRI, cartoon and QR image. Here cartoon image
acquire higher value than others . The result is a low IDM value for
inhomogeneous images, and relatively higher value for homogeneous
images.

Chart 4. ASM
In Chart 4. discussion about ASM features of different
images such as irish, MRI, cartoon and QR image is made. Here cartoon
image acquires higher value than others. Table 2. shows the analysis
based on feature extraction time and Chart 5 displays analysis based on
data
size.
