A novel reversible data hiding method with image contrast enhancement

作者：

Highlights：

•

• A novel method is proposed for reversible image contrast enhancement.

• Better image quality can be obtained by applying the proposed method.

• Automatic contrast enhancement can be implemented with the proposed method.

• Five image quality metrics are used to assess the contrast-enhanced images.

• Experimental results have validated the efficacy in image quality preservation.
