SYSTEM AND METHOD FOR EMBEDDING INFORMATION IN DIGITAL SIGNALS |
摘要 |
A lossless, reversible data embedding technique uses a generalization of least-significant-bit modification. The portions of the signal that are susceptible to embedding distortion are compressed and sent as part of the embedded payload. A prediction-based conditional entropy coder uses unaltered portions of the host signal to improve lossless data capacity. |
