Robust Digital Watermarking Algorithm Based on Image Geometric Correction and SVD of Block Compressive Sampling Measurements
摘要
Abstract
It will lead to the poor robustness when the watermark is directly embedded into the compressive sampling measurements.To solve this problem,a robust digital watermarking algorithm based on image geometric correction and singular value decomposition (SVD)of block compressive sampling measurements is proposed in this paper.The water-mark is embedded into the singular values of the image in compressive sampling transform domain.Meanwhile,the water-marked image under geometric attacks is corrected using the image normalization technique.After geometric correction, the watermark can be correctly extracted.Experimental results have shown that the proposed algorithm achieves the bet-ter robustness to common attacks and geometric attacks.关键词
