Abstract
In this paper we propose a technique to embed a digital watermark containing copyright information into a spectral images. The watermark is embedded by modifying the singular values in PCA/DWT domain of the spectral images. After modification the image is reconstructed by inverse processing, thus containing the watermark. We provide analysis of watermarkâs robustness against attacks. The attacks include lossy compression and median filtering. Experimental results indicate that the watermark algorithm performs well in robustness.
