The XOR coding, on the other hand, is a simple, yet effective, process that helps in reducing differences between the cover and stego images.
According to renewal theory, the differences between the Cover and No Cover conditions may be due to the fact that in the Cover condition, a context change has taken place (Bouton and Bolles 1979).
For example, the increase in solar radiation and ambient temperature increases the still temperature, and the difference between the cover inner and outer temperatures enhances the condensing process and water productivity.
To minimize the difference between the cover- and the stego-medium, recent steganography techniques utilize natural limitations in human auditory and visual perceptions.
In other words, the difference between the cover-block and the stego-block is never more than, and the embedding capacity of a block equals.
After etching for 4 h in KOH solution and removal of the gold layers, there was no etching difference between the covered and exposed surfaces on the crystal quartz surface (Figure 8a).
However, as in the other experiments, we found a significant difference between the Cover and No Cover conditions in the Test phase.
Although the difference between the Cover and No Cover conditions tended to be smaller than in Experiment 1, in Session 1, which was uncontaminated by further extinction, there was again a clearly significant difference (p = 0.008).
Further analyses with the Bonferroni adjustment for multiple comparisons of difference scores within the first and the last test sessions revealed a significant difference between the Cover (M = 26.86, SEM = 5.02) and the No Cover (M = 10.44, SEM = 3.76) conditions for the first test session, t(14) = 2.62, p = 0.02.
Temporal, spatial, and attribute differences between the land cover product and pre-existing validation data can result in inconclusive depictions of map accuracy.
