Abstract:

A new video watermarking algorithm based on the 1D DFT (one-dimensional discrete Fourier transform) and Radon transform was proposed in this paper. The 1D DFT for a video sequence generates an ideal domain. The frames with highest frequency were chosen to embed the watermark in the Radon transform domain. The performance of the proposed algorithm is evaluated by video compression standard H.264 with three different bit rates; geometric attacks such as rotation, translation, and aspectratio; and other attacks like frame drop, frame swap, spatial filtering, noise addition, lighting were conducted. The results show that the algorithm is robust to the attack. One of the most important advantages of this video watermarking algorithm is its simplicity and practicality.
