研究目的
To propose a robust multiple watermarking algorithm suitable for the lossy transmission of color images with compressed sensing, aiming for digital rights management applications.
研究成果
The proposed multiple watermarking algorithm effectively embeds watermarks into CS coefficients of color images, demonstrating robustness against lossy transmission. High reconstruction quality and watermark extraction accuracy are achieved, making the algorithm suitable for copyright protection in digital rights management applications.
研究不足
The study does not detail the computational complexity or the scalability of the proposed algorithm to larger datasets or different types of multimedia beyond color images.
1：Experimental Design and Method Selection:
The study employs discrete cosine transform (DCT) for sparsity and compressed sensing for compression. Watermarks are embedded into CS coefficients of different color planes.
2：Sample Selection and Data Sources:
A color image of size 256×256 is used for simulations.
3：List of Experimental Equipment and Materials:
Not explicitly mentioned.
4：Experimental Procedures and Operational Workflow:
The original image is separated into red, green, and blue planes. CS is applied to each layer, and watermarks are embedded into selected planes.
5：Data Analysis Methods:
Peak signal to noise ratio (PSNR) and structured similarity (SSIM) are used to assess watermarked image quality. Bit correct rate (BCR) evaluates watermark extraction accuracy.
