PERFORMANCE EVALUATION OF VIDEO WATERMARKING

A digital watermark is added to a image/frame, is a more or less visible information in the form of a text, logo, audio etc. that has been added to the original image, audio or video. The added information can be more or less transparent to make it either easy or hard to recognize the watermark. Video watermarking is relatively an innovative tool that has been proposed to solve the problem of illegal manipulation and sharing of digital video. It is the process of embedding copyright information into video watermarking. In this paper, we use DWT (discrete wavelet transforms) and SVD (single vapour decomposition) for embedding video watermarking algorithm and then we use IDWT (inverse discrete wavelet transforms) for extracting the video watermarking. For this video embedded and extraction of watermarking process we include image watermarking to get easy video watermarking and better understanding. The performance of the proposed algorithm is analyzed by using MSE, PSNR by adding attacks.
