Rotation-Invariant Spherical Watermarking via Third-Order SO(3) Representation Coupling
Researchers have developed a novel watermarking technique for panoramic images that remains robust to arbitrary 3D rotations by leveraging SO(3) representation theory and spherical harmonics. The method embeds watermarks into higher-order spherical harmonic coefficients and recovers them using rotation-invariant bispectral scalars, achieving near-perfect robustness while maintaining visual quality.
