Video Watermarking Algorithm Based on DCT and SVD

Abstract:

This paper presents an original video based on DCT (Discrete Cosine Transform) and SVD (singular value decomposition) algorithm combined adaptive watermark embedding algorithm. Algorithm will first split the video stream into different scenes, each frame of the discrete cosine transform, and its singular value decomposition of the DC coefficient; the original watermark image and after scrambling algorithm using singular value decomposition singular value sequence, and finally watermarked image. Experiments show that the algorithm meet the invisibility requirements also meet the robustness requirements, efficiently against attacks as frame dropping, Gaussian Noise and Compression attack.
