Abstract:
This paper presents a high-fidelity steganography method for 3D Gaussian splatting that requires no additional training. We propose a bit-level embedding technique that leverages the lower bits of the 32-bit floating-point representation. We further introduce an embedding strategy that considers each Gaussian’s opacity and incorporates RSA encryption.
