Effective Video Quality Estimation Using Wavelet Based Watermarking Technique

Image and video quality measurement is a challenging problem in many of the image processing fields. The paper addresses the Image Quality Assessment (IQA) problem using the objective metrics of the watermarks. The proposed scheme helps to assess the quality of a video by using a tree structure based watermarking method without accessing the cover video.Process of the watermarking is done in the wavelet domain of the cover video .The watermarking coefficients are embedded in the selected trees of the decomposed video.Comparing the original watermark and the extracted watermark will indicate the quality degradation of the original cover video. Applications of video watermarking in copy control, broadcast monitoring, finger printing, video authentication, copyright protection etc is immensely rising Performance can be evaluated in terms of the PSNR,SSIM under different distortions.
