Abstract
In this paper, we suggest a new watermarking scheme. The purpose of this technique is based on image content description and specifically the corner points. In our proposed scheme, Harris detector is used for get some corner points, which are united with a rectangle decomposition method in order to get a set of insertion blocks and to bind the watermark with the image content. The proposed scheme is divided into two phases: The embedding scheme, where we embed the watermark into the original image (one bit of message in each rectangle insertion block) to get the watermarked image. The extracting scheme is the reverse phase that aims to extract the embedded message from the watermarked image. The experimental results demonstrate that the proposed scheme preserves the image visual quality (PSNR up than 53 dB) and with less algorithm complexity (0.3 s as average) and we arrive to detect 100% of message embedded (messages between 9 to 20 bits) in various images.
