Performance analysis of combined discrete fourier transformation (DFT) and successive division based image watermarking scheme

Abstract

A combined Discrete Fourier Transformation (DFT) and Successive Division based image watermarking scheme has been proposed in this article. Due to intrinsic parameters: Imperceptibility, Data Embedding Capacity and Time of Execution, many spatial domain approaches are less efficient. Many frequency domain approaches satisfies imperceptibility and data embedding capacity, but utilizes more execution time. The proposed algorithm is a hybrid technique under frequency domain, which embeds watermark into host using Discrete Fourier Transformation (DFT) and successive division. Through DFT better imperceptibility is noticed and the algorithm utilizes very less execution time compared to other existing approaches. Performance analysis is done based on similarity between original and retrieved watermark images. The experimental results are better compared to other existing techniques.
