Abstract |
|
Recently, digital watermarking algorithms are widely applied to digital image, audio or video for ownership protection and tampering detection. Digital watermarking is the process of reversibly or irreversibly embedding information into a digital signal. In this paper, Video watermarking algorithm based on discrete wavelet transform scheme is proposed. In which, the video is firstly divided into frames and each frames are divided in to three images of red, blue and green, then 4-level DWT (Discrete Wavelet Transform) is performed on each digital image. Here watermarking data is also color binary video, which is also first divided into frames and then three images are taken from each frame. Watermark frames are embedded into the original video frames according to the attribute of the sub-band (LH, HL) of every wavelet images. The simulation results show the effectiveness of the scheme. |
