Index mapping based hybrid DWT-DCT watermarking technique for copyright protection of videos files

A Survey on Robust Video Watermarking Algorithms for Copyright Protection

“…To combine the advantages of different transformation methods to better improve the performance, many watermarking algorithms in the hybrid domain have emerged [62][63][64][65][66]. In a previous paper [62], scene identification and scene summarization were adopted to generate the video summary, and then the summary was used to detect the first type of feature regions by using the crowdsourcing technique.…”

“…To resist frame blending and projection attacks, Gaj et al [63] combined DCT and 3D-DWT together to embed the watermark. Depending on the energy compression property of DCT and the multiresolution property of DWT, some hybrid DWT/DCT-based video watermarking algorithms have been proposed [64,65]. In another past paper [66], a zero-video watermark algorithm based on 2D-DWT and pseudo-3D DCT was proposed.…”

Robust Digital Watermarking Techniques for Protecting Copyright

“…In general, four key standards are used to determine the accuracy of the watermarking system. It is not visible, robust, eager or blind [2]. A digital watermark is a code containing data regarding the creator of the work, the copyright owner of the registered consumer and the rights to the property of that particular information.…”

“…The test findings demonstrate that, in the case of compression, cropping, scaling and other noise, the proposed system results in greater robustness and less distortion than other existing JPEG2000 implementations. A. Kunhu et al [2]This paper proposes a new technique of blind colour video watermarking for the protection of interactive colour videos by means of index mapping. The latest feature of the approach is the design of the dynamic video watermarking of the watermarks logo utilising the Index Mapping technique based on the hybrid, discreet wavelet transformation (DWT) and the discreet cosine transform (DCT).…”

Improved Method for a Secure Image Cryptography Based on Rsa and Des Algorithm and LSB Steganography Technique

“…The proposed video watermarking algo provide improved imperceptibility within harmony by way of human visual system and offers advanced toughness in opposition to signal processing attacks. [5] Ch.Sathi Raju et.al (2016) Compression is serious trouble in applications of capsule endoscopy. In this paper hybrid DCT compression method and DWT compression method is being employed to capitalize advantages of together techniques.…”
