Abstract

In the modern digital life, the increased important roles of digital content invites new challenges for securing the exchange of digital media. This paper addresses a unique, best copyright protection and watermarking scheme for videos. In the video watermarking chrominance, channel of the selected frames is decomposed into two types of even and odd shares of video frames. For embedding, if odd share is selected, then DT-CWT (Two dimensional Dual Tree Complex Wavelet Transform) is applied on it. Video watermarking has two main process - watermark embedding and watermark extraction process. Before the watermarking embedding process, the input video sequence is converted into a number of single frames. Here the authors have applied Singular Value Decomposition and Dual Tree Complex Wavelets Transform on watermark image.
