Performance Analysis of Various Image Watermarking Techniques using different Image Quality Parameters

Abstract

Digital technologies is showing tremendous growth and advancements in image transmission and processing during last few years. The image security during image transmission is one of the important areas for research. Various digital watermarking techniques are nowadays become popular for image security and copyright. But, due the rapid growth of the Internet and the development of digital multimedia technologies, illegal copying, modifying and copyright protection have become very important issues. Hence, there is a strong need of development of technique which will able to face these hurdles. There are various techniques to produce the watermark in digital images. In this paper, SVD, DCT, DWT and mixed watermarking techniques has been used for watermarking. The performance parameter like PSNR, MSE, MSSIM and WPSNR are used to evaluate the watermarking performance. The experimental results are shown in this paper for various methods.
