A WATERMARKING SCHEME FOR REMOTE SENSING IMAGES BASED ON CONTOURLET TRANSFORMATION
摘要
Abstract
Against problems of existing transformation domain watermarking algorithms for remote sensing images, the paper proposes a digital watermarking scheme for remote sensing images based on Contourlet transformation. At first,it normalizes a host remote sensing image. Then it scrambles the watermark image by Arnold;through line scanning the scrambling watermark image into one-dimensional vector,it uses the acquired binary watermark sequence as digital watermark information. Finally, it applies Contourlet transformation to the host remote sensing image and embeds the watermark into the selected Contourlet transformation coefficients by quantitative parity. Experiments have shown the algorithm's good robustness against JPEG compression, filtering and noise attacking,as well as against geometric attacks such as rotation,scaling,and moving etc.关键词
