Abstract
In this work, a novel and efficient digital video watermarking technique based on the Singular Value Decomposition performed in the Multiresolution Singular Value Decomposition domain is proposed. While most of the existing watermarking schemes embed the watermark in all the video frames, which is time-consuming and also affects the perceptibly of the video quality, the proposed method chooses only the fast motion frames in each shot to host the watermark. In doing so, the number of frames to be processed is consequently reduced and a better quality of the watermarked video is also ensured since the human visual system cannot notice the variations in fast moving regions. The watermark information is embedded by Quantization Index Modulation which is a blind watermarking algorithm. The experimental results demonstrate that the proposed method can achieve a very good transparency, while being robust against various kinds of attacks such as filtering, noising, compression, and frame collusion. Compared with several methods found in the literature, the proposed method gives a better robustness.
Highlights
In recent years, the fabulous growth of the internet technology and the expansion of powerful computing devices have boosted the multimedia electronic commerce up and incited artists to share and promote their work online
We propose a novel video watermarking scheme in fast motion frames using Singular Value Decomposition in the Multiresolution Singular Value Decomposition (MR-SVD) domain
We carried out various experiments and found that the block size of 16x16 allows the embedding of an acceptable number of watermark bits without causing noticeable block effect
Summary
The fabulous growth of the internet technology and the expansion of powerful computing devices have boosted the multimedia electronic commerce up and incited artists to share and promote their work online. This obviously implied a massive presence on the web of digital multimedia data such as audio, image, and video. The embedding procedure consists of inserting in the host multimedia content (usually called the cover) a watermark which is a digital signature that holds copyright information exclusively limited to the owner. By means of the given secret keys, the extraction procedure permits solely to the owner or to an authorized recipient of the digital content to retrieve the watermark from the watermarked content [2]
