Optimum Watermark Detection in Color Images
نویسندگان
چکیده
This work concentrates on the problem of watermarking embedding and optimum detection in color images through the use of spread spectrum techniques, both in space (Direct Sequence Spread Spectrum or DSSS) and frequency (Frequency Hopping). It is applied to RGB and opponent color component representations. Perceptive information is considered in both color systems. Some tests are performed in order to ensure imperceptibility and to assess detection quality of the optimum color detectors

متن کاملColor image watermarking using channel-state knowledge
This work concentrates on the problem of watermarking embedding and blind optimum detection in full-frame DCT domain using channel-state knowledge concepts. Minimum length sequences are used to embed the watermark information in the color components. Each chip of the sequence is inserted in a random-like fashion in those coefficients that ensure imperceptibility, robustness and a very low proba...
متن کامل“ Multiple Channel Watermarking of Color Images ”
A novel scheme for the watermarking of color images is presented in this communication. An attempt has been made to find the most appropriate alternative to the RGB color space. Color spaces with linear relation to the RGB color space with uncorrelated components are found to be most suitable for watermarking. Another objective has been to propose an adaptive watermarking scheme for any type of...
متن کاملPerformance Analysis of a Block Complexity Based Data Embedding (abcde) for Color Images in Spatial Domain
The watermarking techniques for grayscale images can be easily extended to handle color images, for this purpose, watermark casting is done by generating three different watermark patterns SR, SG, SB, one for each RGB channel and modifying for each channel, the intensity of the pixels that belong to the corresponding sets AR, AG, AB. The watermark casting and detection procedures for color imag...
متن کاملMaximum-Likelihood Based Watermark Detection on Fingerprint Images
The integrity and security of fingerprint images can be achieved by using watermarking techniques. We introduce Maximum-Likelihood (ML) watermark detection method to detect an invisible watermark within discrete wavelet transform (DWT) coefficients of fingerprint images. Such an optimum technique, which is based on Bayes’ decision theory and the Neyman-Pearson criterion, requires parameters of ...
