Paper Abstract

This paper presents a novel digital image watermarking scheme that is invariant to rotation, scaling, and translation (RST). We embed watermark in the log-polar mappings of the Fourier magnitude spectrum of an original image, and use the phase information of the original image to rectify the watermark positions. The scheme avoids computing inverse log-polar mapping (ILPM) to preserve image quality and avoid exhaustive search to save computation time and reduce false detection rate.
