“…Among the several moment-based methodologies [158] incorporating moments as information carriers, new moment families [78,166,139,140,154,155], moments with improved local behavior [185,26,118,119], RST (Rotation, Scale, Translation)…”

“…The most emerging topics in moment-based watermarking is the application of the newly proposed quaternion moments as features to hide the watermark information inside color images [157,156,167] and the tackling of watermarking as an adaptive process [159,119,156,154,140] where the signicance of each moment coecient and the image insertion portion are dynamically decided.…”

This chapter aims to analyze the research eld of moments and moment invariants in a holistic way. Initially, a literature analysis of the last 50 years is presented and discussed in order to highlight the potential of this topic and the increasing interest in many disciplines. A more in depth study of the issues addressed through the years by the researchers is next presented both in theory and applications of moments. The most representative works in each research direction are discussed in a chronological order to point out the progress in each specic eld of action. This analysis concludes with the challenges and perspectives that should motivate researchers towards the promotion of the moments and their invariants to new scientic horizons. For the rst time, this chapter gives a global overview of what happened in the last 50 years in moments and moment invariants research eld, but most of all it brings to light the open issues that should be addressed and highlights the rising topics that will occupy the scientists in the coming years. This chapter serves as a guide to those who nd the eld of moments and moment invariants a brilliant eld of action since it encloses all the milestones of this eld.

“…The recent proliferations are copying data illegally, tampering and copyright protection in internet and multimedia. To protect the copyrights of such digital multimedia contents a standard elucidation is required.Digital image watermarking is one of the emerged solutions for protecting such multimedia contents [1].An effective Image watermarking has to meet the basic requirements of robustness, embedding capacity, visual imperceptibility and uniqueness for copyright protection, content archiving, meta-data insertion, broadcast monitoring, tamper detection and digital fingerprinting [2,3]. Generally the image watermarking techniques are classified as spatial domain watermarking techniques and frequency domain watermarking techniques.Spatial domain techniques are economical and easy to implement where the watermarks are directly inserted by simply varying the pixel values of the cover image.…”

The main objective of the majority of research in Digital Image Watermarking technique is to improve the robustness of attacks.In this paper, a new algorithm has been proposed based on Discrete Wavelet Transform, Discrete Cosine Transformation in association with Singular Value Decomposition for embedding the dual watermark which provides an efficient copyright protection.Here the primary watermark is embedded into the secondary watermark and the resultant image is used as a watermark for the host or cover image. The primary and secondary watermarks are retrieved back by using an efficient watermark retrieving algorithm. During the processes of embedding the scaling factor is varied to improve the quality of watermarked image. In this proposed algorithm the watermarked image is extracted back with same quality, high peak signal to noise ratio and normalized correlation coefficients. The quality of the extracted watermarks is authenticated using Peak Signal to Noise Ratio and Normalized Correlation Coefficient. Compared with previous methods the proposed algorithm has a significantly higher robustness against various geometrical and removal attacks.Nearly 28 attacks like Cropping, Rotating at various angles, Sharpening, Motion Blur, rescaling, resizing and adding noise like Salt and Pepper noise, Gaussian noise, Spackle noise, filters like average filter, median filters are attempted. Even after attempted all such attacks both the watermarks are retrieved back with the same quality and high normalized correlation coefficient.
