Color image watermarking based on orientation diversity and color complexity

作者：

Highlights：

• The orientation diversity is considered into contrast masking modelling.

• The color complexity is first introduced to adjust the final JND model.

• The proposed JND is implemented into logarithmic STDM watermarking framework.

• The proposed scheme shows a better tradeoff between fidelity and robustness.
