Abstract
The distribution of digital products like audio and video are increasing rapidly over the networks, so the owners of such digital data are worried about their ownership protection. It may be possible that the third- party may claim the digital products as their own and misuse it in future. In order to overcome this problem, 'Video Watermarking Scheme Based on Principal Component Analysis and Wavelet Transform for Copyright Protection', is introduced for preventing illegal copying of their digital products. In this system, a Binary logo watermark is embedded in video frames for copyright protection. Principal Component Analysis (PCA) is applied to each block of the two bands (LL - HH) which results from Discrete Wavelet transform of the video frame. The watermark is embedded into the principal components of the LL blocks and HH blocks at different levels. Combining the DWT and PCA transform improves the performance of the watermark algorithm. This watermarking scheme shows no visible difference between the watermarked frames and the original frames i.e. imperceptible to the Human Visual System (HVS). It depicts the robustness against a wide range of attacks such as geometric transformation, histogram equalization, and gamma correction.
