Blind watermarking for color images using EMMQ based on QDFT

作者：

Highlights：

• EMMQ incorporated EPA, MPSAM, and MM within a QDFT-based blind watermarking.

• EPA is first pre-worked to ensure that the watermark is correctly embedded.

• MPSAM is used to enable the mapping of multiple bits within a single QDFT block.

• MM allows watermarked image superior image quality and strong resistance to attacks.

• PSO makes it possible to optimize the EMMQ parameters.
