基于雅克比-傅里叶矩的数字图像水印方法
Image watermarking based on Jacobi-Fourier moment
摘要
Abstract
This paper presents a new digital watermarking scheme using the Jacobi-Fourier moment(JFM), a kind of con-tinuous orthogonal moment. JFMs are defined on the polar coordinates, and the magnitudes of JFMs are invariant to image rotation. In this paper, the properties of JFMs are investigated, and a binary watermark sequence is embedded into the invariant magnitudes of some selected JFMs by quantization. Besides, the watermark can be extracted from the magnitudes of JFMs without the original image. Simulation results show that the proposed method can resist both geometric attacks and traditional signal processing attacks, such as rotation, scaling, flipping, JPEG compression, median filtering, etc.关键词
