MATLAB Implementation of Digital Watermarking with Hypercomplex Frequency Domain Algorithm
This presents a novel watermarking algorithm for color carrier images using hypercomplex frequency domain processing. The method employs Fast Hypercomplex Fourier Transform (FHFT) to embed watermarks in selected frequency bands while modifying symmetric coefficient values, ensuring the watermarked image maintains RGB transmission compatibility. Through analysis and MATLAB implementation, the algorithm demonstrates effective error diffusion across RGB channels via inverse hypercomplex Fourier transform, achieving optimal balance between watermark imperceptibility and security. The proposed "cross-redundant embedding" strategy further enhances robustness, with experimental results validating the algorithm's superiority.
