Rotation-Invariant Spherical Watermarking via Third-Order SO(3) Representation Coupling 事件

Rotation-Invariant Spherical Watermarking via Third-Order SO(3) Representation Coupling arXiv:2605.26702v1 Announce Type: new Abstract: Reliable watermarking of panoramic imagery is fundamentally challenged by arbitrary 3D rotations. As panoramas are defined on the sphere, they naturally transform under the action of $SO(3)$, rendering conventional planar representations and augmentation-based robustness strategies inadequate and devoid of theoretical guarantees. To address this, we formulate p
