“…subbands S6-S8, there is a substantial improvement with the proposed technique as compared to the prior work. Thus, the proposed technique could also be very helpful for digital watermarking applications [19,20] that mostly utilize the middle frequency regions to conceal the watermark message bits. Figure 5 demonstrates the performance of the proposed technique in terms of different images.…”

“…In [6], a novel watermarking approach was proposed by combining the both GA and PSO to obtain an improved performance in watermarking criterion. However, [6] decomposes the image through the most popular Discrete wavelet transform (DWT) which is having main problem of information loss. Due to the down sampling process in DWT, the extracted watermark and also the host image can't recover entire information.…”

“…With lifting wavelets the inverse transformation is undoing the operations of forward transform which reduce the artifacts during transformation. An intelligent reversible watermarking scheme for medical images using Differential Evolution is proposed in [22] and an intelligent reversible watermarking scheme using GA and PSO is proposed in [23].…”
