Abstract

In this proposed work a new and fast technique has proposed for watermarking of real time video using discrete wavelet transformation (DWT) frequency domain. Lab View and IMAQ vision software package has been utilized to achieve the proposed method of real time video watermarking. The use of Lab View and IMAQ toolbox present a complete set of digital image processing and acquisition function that improve the efficiency of the project and reduce the programming effort of user obtaining better result in shorter time. In this method the real time video has been captured from the external device, in this work laptop from camera has used for input of video to be watermarked in audio video interleave (AVI) format has taken, which is then converted into number of frames. Each frame of the video is then embedded with watermarked using blind wavelet function. In this method the level of DWT can be easily controlled. Multi resolution analysis has been performed on watermarked video and peak signal to noise ratio (PSNR) and mean square error (MSE) values has taken out to get the performance accuracy and quality of watermarked video which actually depicts the efficiency and performance of watermarking technique and the results of these has compared to one of the existing technique.
