4.2. Results and Discussion The experimental findings are presented in Table 2, where the PSNRs, MSEs, and hiding capacity are shown. For the proposed scheme, in terms of hiding capacity, the highest hiding capacity is 201,364 for the image of Lena. While the lowest hiding capacity is 104,284, as experienced by the image of the baboon. On average, the hiding capacity is 171,529. This means 60% of the test images exceed the average hiding capacity.
