Blind robust image watermarking based on adaptive embedding strength and distribution of quantified coefficients

作者：

Highlights：

• Present a new adaptive embedding strength of the selected DCT coefficient.

• A new formula to estimate the distortion unit for selecting the watermark position.

• Use the block selection strategy to modify blocks with less simulated distortions.

• Investigate the robustness and imperceptibility of the various imaging attacks.
