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.
