“…is about 7 times smaller than that of the proposed scheme. Although the method of Teng et al (2010) has acceptable PSNR values, its payload values are also about 6 times smaller than that of the proposed scheme and its PSNR results are diving when the payload is increased to 0.07 bpp. On the other hand, the method by Khrisna et al (2010) has almost similar payload sizes as the proposed scheme.…”

“…The proposed scheme's numerical performance is shown in table 6. Figure 10 provides PSNR and data embedding capacity comparisons between the proposed (using both schemes described above to increase capacity) and five other classical methods (Thanuja et al 2008;Teng et al 2010;Khrisna et al 2010;Lin & Chang 2007;Chang et al 2008) after increasing payload size.…”

The main purpose of this presented work is to develop a data embedding method based on a new digital image histogram modification approach. The proposed scheme fundamentally is concerned about the frequency of occurrence of the image brightness values of the cover image for the data embedding procedures. The proposed scheme effectively realizes both perceptual invisibility and statistical invisibility so that obtained covered images are highly robust against common perceptual and statistical steganalysis techniques. The scheme provides reasonably higher payload values than its counterparts, as well as providing comparatively improved PSNR results.

“…Above all, Ni et al's (2006) method offers very low data embedding capacity making it very unsuitable in current steganography applications. Teng et al (2010) slightly improved Ni et al's method detailed above. In accordance with Ni et al's method, the data hiding capacity of the cover image directly depends on the frequency of occurrence of the pixels.…”

“…Lee et al (2006) also proposed a reversible data hiding scheme based on histogram modification of difference images. To increase data hiding ability, Chang et al (2008) presented an efficient extension of the histogram modification technique by considering the pixel difference instead of simple pixel value and Teng et al (2010) had some other similar proposals. They also exploited a histogram shifting technique to prevent problems raised about overflow and underflow.…”
