Imperceptibility—Robustness tradeoff studies for ECG steganography using Continuous Ant Colony Optimization
作者：
Highlights：
• ECG steganography is performed using DWT–SVD and quantization watermarking scheme.
• Imperceptibility-robustness tradeoff is investigated.
• Continuous Ant Colony Optimization provides optimized Multiple Scaling Factors.
• MSFs are superior to SSF in providing better imperceptibility-robustness tradeoff.
