“…Singular value decomposition (SVD) is used to embed the watermark image in to the cover image. Author conclude that, PSNR value for different combination of images and for various sub bands, is more when HH sub band is used for transmission and also concludes that PSNR value of the extracted watermark is increases after addition of Gaussian filter watermarking [6].…”

Abstract:Watermarking is the process of hiding the digital information, such as image, audio and video. It is typically used for authentication and copyright. Communication is a major part in our day-to-day life, now a day's exchanging of information in the form of image, audio and video takes place through internet. There are some issues or threads associated with internet transformation with respect to intellectual property rights (IP rights) like forgery, authentication and copyrights. In this paper we limit the survey to images only and we present a detailed survey of existing and newly existing watermarking techniques.

The modern applications of communications that use wideband signals suffer the lacking since the resources of this kind of signals are limited especially for fifth generation (5G). The Compressive Spectrum Sensing (COMPSS) techniques address such issues to reuse the detected signals in the networks and applications of 5G. However, the raw techniques of COMPSS have low compression ratio and high computational complexity rather than high level of noise variance. In this paper, a hybrid COMPSS scheme has been developed for both non-cooperative and cooperative cognitive radio networks. The proposed scheme compiles on discrete wavelet transform – single resolution (DWT-SR) cascaded with discrete cosine transform (DCT). The first is constructed according to the pyramid algorithm to achieve 50% while the second performed 30% compression ratios. The simulation and analytic results reveal the significant detection performance of the proposed technique is better than that of the raw COMPSS techniques.

In this paper, an algorithm for digital image watermarking which utilizes the hybridization technique is presented. The hybrid technique is formulated by combining the Redundant Wavelet Transform (RDWT) with Fractional Fourier Transform (FrFT) and Singular Value Decomposition (SVD). In this technique, watermark information is embedded in the low frequency band of Redundant Wavelet Transform. To increase the robustness, FrFT is implemented on low frequency coefficients of RDWT. Experimental results have been demonstrated on the basis of Peak Signal to Noise Ratio (PSNR), Correlation Coefficient (CC), and Gradient Magnitude Similarity Deviation (GMSD). A comparable improvement is witnessed from the results in terms of qualitative and quantitative analysis. The experimental results prove to be robust against various image processing and geometrical attacks applied on the standard test images.
