Design Method of H.264/AVC Video Watermarking Based on Intra Prediction Coding

Abstract:

Aiming at problems meet in the copyright of H.264/AVC video, a method of digital watermarking based on intra prediction coding. The method combines wavelet transforms, chaos theory and spread spectrum modulation to preprocess grayscale image. Then according to different intra prediction mode of I-frame brightness sub block, selects different DCT coefficient, and embeds the watermark information by improved LSB algorithm. Experiments show that, this method ensures video effects without distortion, high blind detection accuracy, and little effect on code rate.
