A Multiple Frequency Band Watermarking Algorithm Based on Stripe Image
Abstract:
In this paper, a multiple frequency band watermarking algorithm based on stripe image is proposed. The algorithm converts watermark string representing the copyright of image works to stripe image before embedding it to host image. Because of the error correction ability of the stripe image, the algorithm takes on high robustness. This paper also proposed a multiple frequency band embedding strategy through analyzing and classifying various watermark attacking algorithm. Applying this algorithm, watermark can stand several kinds of attacks such as low pass filter and high pass filter. Experimental results show that a blind watermarking algorithm with high robustness to various watermark attacking can be achieved through combining stripe image coding and multiple frequency band strategy.
