A fusion-domain color image watermarking based on Haar transform and image correction

作者：

Highlights：

• The Haar coefficient can be calculated directly in the spatial domain.

• The geometrically attacked watermarked image can be corrected.

• Different quantization steps are selected in different color channels.

• Affine transform is used to encrypt the color watermark.
