An Efficient Watermarking Approach For Digital Images
نویسندگان
چکیده
Digital Watermarking technique is used to embed the useful information in a transmission media for copyright protection, authentication and broadcast monitoring etc. This paper describes an image hiding method using Fast Fourier Transform (FFT) algorithm which calculates the Peak Signal to Noise Ratio (PSNR) values and compare them with Gray Scale and Discrete Cosine Transform (DCT). The experimental results show that the quality and embedding capacity of watermarked image for this scheme is higher as compared to other existing watermarking schemes.

متن کاملIntelligent scalable image watermarking robust against progressive DWT-based compression using genetic algorithms
Image watermarking refers to the process of embedding an authentication message, called watermark, into the host image to uniquely identify the ownership. In this paper a novel, intelligent, scalable, robust wavelet-based watermarking approach is proposed. The proposed approach employs a genetic algorithm to find nearly optimal positions to insert watermark. The embedding positions coded as chr...
