摘要

Nowadays, the digital copyrights are the common concern in the Multimedia Digital production industry and these copyrights apply various watermarking techniques. In this paper we present a method for a robust watermarking insertion in a video frame. The proposed method works on the uncompressed video based on the spread spectrum communication. The researchers applied the technique in the discrete wavelet transform domain (DWT). The results showed that the watermark has high perceptual invisibility and robust against JPEG compression, geometric distortions such as Downscaling, Cropping, and Rotation, as well as noising. The watermark was successfully extracted from the video after various attacks.
