3. Technical feasibility analysis

1.Full recovery possibility: Theoretically, it is irreversible after the original pixels are overwritten, and existing technologies are all “intelligent speculation”

2.Factors affecting success rate: Mosaic strength > Original image quality > Algorithm advancement > Processing time

3.latest breakthrough: MIT research team improves restoration accuracy by 15% through "texture synthesis" technology (2023)

4. Legal and Ethical Controversies

1.Privacy Invasion Risk: A Japanese artist’s photos were maliciously restored, triggering legislative discussions

2.Double-edged sword of technology: Can be used to restore historical documents and may also be used to crack privacy protection

3.Performance expectation management: The difference in comparison test results between different tools can reach 60%

Conclusion

Demosaic technology is developing rapidly, but its application must be established within a legal and ethical framework. Users need to clarify technical boundaries, and developers should establish protection mechanisms to prevent technology abuse. "Anti-reduction mosaic technology" may appear in the future, and this offensive and defensive battle will continue to evolve.
