Abstract
In this paper, a digital watermarking technique for copyright protection or ownership identification of digital media is introduced. In the proposed scheme, a novel classifier is employed to measure the visual activity of the image blocks. The proposed approach utilizes the level of visual activity within the host image and modifies the intensities of some pixels in image blocks accordingly. The described technique, is an invisible, image watermarking technique in the spatial domain and the experimental results show that the watermark can be extracted properly under image processing and destroying operations.
