[0071] The purpose of the present invention is to provide a color-blind watermarking method based on Hamming code, eigenvalue decomposition and image correction, which is characterized in that it is realized through four processes, specifically including a preprocessing process, a watermark embedding process, an image correction process and a watermarking process. Extraction process:
[0072] Process 1: Preprocessing process, the specific steps are described as follows:
[0073] Step 1: Preprocessing of the color host image: Perform dimensionality reduction processing on the 3D color host image H with a size of 512×512×3 to obtain three 2D layered host images H of red, green and blue p , and divide the pixels in each layer into 2×2 non-overlapping pixel blocks, p=1, 2, 3 respectively represent three layers of red, green and blue;
[0074] Step 2: Preprocessing of the color watermark image: Perform dimensionality reduction processing on the 3D color watermark image W with a si...
