Lossless medical image watermarking method based on significant difference of cellular automata transform coefficient

作者：

Highlights：

• A robust lossless medical watermarking scheme for copyright protection is proposed.

• The CAT coefficient is used to produce an OSI for verifying the medical image.

• The appearance of OSI is meaningful information to promote its management.

• Our scheme can keep the quality of the medical image for copyright protection.
