A Robust Non-blind Algorithm for Watermarking Color Images using Multi-resolution Wavelet Decomposition
Research in the field of watermarking is flourishing providing techniques to protect copyright of intellectual property. Among the various methods that exploit the characteristics of the Human Visual System (HVS) for more secure and effective data hiding, wavelet-based watermarking techniques showed to be immune to attacks; adding the quality of robustness to protect the hidden message from thi...
متن کاملAn Efficient Non-blind Watermarking Scheme for Color Images using Discrete Wavelet Transformation
In this paper we present a new invisible robust non blind watermarking scheme. The proposed scheme embeds the monochrome (logo) watermark into the high and middle {HL, LH, HH} frequency bands of luminance channel of the color image. The Red (R), Green (G) and Blue (B) channels of color image are transformed into Luminance (Y), Intensity (I) and Hue (Q) Channels, the Luminance channel of color i...
متن کاملA Novel Blind Watermarking of ECG Signals on Medical Images Using EZW Algorithm
Introduction:In this study, ECG signals have been embedded into medical images to create a novel blind watermarking method. The embedding is done when the original image is compressed using the EZW algorithm. The extraction process is performed at the decompression time of the watermarked image. Materials and Methods: The multi-resolution watermarking with a secret key algorithm developed in th...
متن کاملA blind digital image watermarking method using interval wavelet decomposition
In this paper, we present a new blind digital image watermarking method. We introduce interval wavelet decomposition, which is a combination of a discrete wavelet transform and interval arithmetic, and we examine its properties. According to our experimental results, this combination is a good way to produce a kind of redundancy from the original image and to develop new watermarking methods. T...
متن کاملRobust Blind Image Watermarking Based on Multi-wavelet Transform and Singular Value Decomposition
Digital watermarking is a technique for copyright protection of multimedia products such as digital images, which embeds a watermark into a host image. The main challenge in image watermarking is the development of new robust methods against different attacks. This paper presents a robust blind watermarking scheme based on multiwavelet transform (MWT) and singular value decomposition (SVD). By ...
