Abstract :
In recent years, copyright protection becomes more and more important in daily life, especially in digital products. A new algorithm uses 3D slant transform and short video segmentation techniques to embed watermark in the coefficient matrix. The experiment results show that the proposed method can enhance the robustness of original video and resist common watermark attacks.
