Data embedding in digital images using critical functions
作者：
Highlights：
•
• Two novel functions and their characteristics are investigated.
• The “uniform embedding” and “adaptive embedding” frameworks are proposed.
• Some existing methods can be obtained from the proposed frameworks.
• Experiment results show the new methods can obtain better performance.
• Provide general-purpose strategies to acquire new image steganographic methods.
