In this research work adopted the frequency domain watermarking scheme which is embedded using discrete wavelet transform (DWT) singular value decomposition (SVD) and High Boost Filtering (HF). By singular values factoring it represent smaller set of values and it can preserve constructive feature of an original image. After that, apply high boost filtering in decomposed in high frequency sub-band on both images to improve the value PSNR. The MSE, PSNR and NC performance parameters are taken to measure the efficiency of the propose method. The simulated experimentation is done in MATLAB and the simulation results of propose method (DWT-SVD-HF) gives improved results than the existing method (DWT).
The fundamental idea of adjusting put together estimated multiplier depends with respect to adjusting of numbers. This multiplier can be connected for both marked and unsigned numbers. In this paper contemplated an Rounding Based Approximate Multiplier that is fast yet vitality effective. The methodology is to round the operands to the closest example of two. Along these lines the computational concentrated piece of the augmentation is excluded improving rate and vitality utilization at the cost of a little mistake. This methodology is appropriate to both marked and unsigned augmentations. The productivity of the ROBA multiplier is assessed by contrasting its execution and those of some rough and precise multipliers utilizing distinctive plan parameters.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
