Triple-Watermarking Algorithm of Color Image
Xuan Li · Journal of Hebei North University · 2015
A color watermark algorithm was proposed.Watermark image after rotation transform was embedded in DCT coefficient of three color components of carrier image,and selection of embedding positions depends on the human visual characteristics.The extraction results were cross-validated.And the algorithm increased success rate of extraction.The experimental results show that the algorithm is of good invisibility and strength in robustness.
