%X In order to resist geometric attacks,a novel spatial domain image watermarking scheme (FAQ) using feature point and quantization is presented.The main methods adopted include:1) watermark synchronization is achieved by invariant local circular regions which can be generated using image locally most stable feature points;2) fan-shaped sub-regions are generated in a rotation invariant pattern by partitioning the local region,and the watermark bits are embedded in spatial domain by odd-even quantization;3) an odd-even detector is designed to extract the watermark blindly.Experimental results show that FAQ achieves high image quality,and it can efficiently resist traditional signal processing attacks,rotation/scaling/translation (RST) attacks as well as some combined attacks.
