Achieving Resolution-Agnostic DNN-based Image Watermarking: A Novel Perspective of Implicit Neural Representation

no code implementations14 May 2024 Yuchen Wang, Xingyu Zhu, Guanhui Ye, Shiyao Zhang, Xuetao Wei

Unlike previous methods, our method does not rely on the previous reduction process by directly watermarking the continuous signal instead of image pixels, thus achieving resolution-agnostic watermarking.
