Abstract

In the digital world in which we are living, the intellectual property protection becomes a concern especially with the proliferation of files transfer over networks. The ability to access data such as text, images, video, and audio has become quicker and easier for people with little to no knowledge of technology. In this paper, a robust watermarking scheme based on the original image content is proposed and simulated. Steerable pyramid transform is used as an embedding domain to its good spatial-frequency characteristics, and its wide applications in the image/video coding standards. The embedding process aims to insert some information in a digital document to identify its owner later. This process requires the original image to be protected and the watermark image related to the image’s owner. It needs also a threshold value used by Sobel-Feldman operator to extract the original image features. The embedding of the watermark image is performed in high frequency components of the original image. Experimental evaluation demonstrates that the proposed watermarking scheme is able to withstand a variety of attacks and at the same time provide good visual quality of the watermarked image.
