“Robust Video Watermarking using Discrete Cosine Transform and Third level Discrete Wavelet Transform”
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 10
Abstract
Digital watermarking technique is becoming popular for copyright information. The watermark embedded in the digital video may be incorrectly detected and extracted due to lack of appropriate algorithm, so the main concern is to implement the algorithm which is more resistant to different types of attacks. In this paper, a Hybrid video watermark technique has been introduced where DCT and 3 rd level of DWT, for adding more security, is used. PSNR, MSE and NC values of Hybrid technique are analyzed on the basis of different noises and attacks. Hybrid technique is robust against high stream, low stream, frame drop, frame trim attacks.
