Abstract

Watermarking is a component of inserting data into the multimedia, for example, image, audio or video. This study propose a method for video watermarking using hybrid DWT-SVD to protect the copy right of images. In order to improve the efficiency of video watermarking two main processes are used namely 1) watermark embedding process and 2) watermark extraction process. Before embedding process the input video sequence convert into number of frames. Here Singular Value Decomposition (SVD) transforms and DWT is applied in watermark image. The improved artificial bee colony algorithm is proposed for generating random frame for the embedding process. The result obtain from the watermark embedding process is the watermark video sequence. Next watermark extraction process is carried out. It is the reverse process of watermark embedding. In watermark extraction process, it extracts the watermark image from the watermark video sequence. The proposed method is implemented in MATLAB.
