Watermarking is a crucial tool for safeguarding copyrights and can serve as amore aesthetically pleasing alternative to QR codes. In recent years,watermarking methods based on deep learning have proved superior robustnessagainst complex physical distortions than traditional watermarking methods.However, they have certain limitations that render them less effective inpractice. For instance, current solutions necessitate physical photographs tobe rectangular for accurate localization, cannot handle physical bending orfolding, and require the hidden area to be completely captured at a closedistance and small angle. To overcome these challenges, we propose a novel deepwatermarking framework dubbed \textit{Aparecium}. Specifically, we preprocesssecrets (i.e., watermarks) into a pattern and then embed it into the coverimage, which is symmetrical to the final decoding-then-extracting process. Tocapture the watermarked region from complex physical scenarios, a locator isalso introduced. Besides, we adopt a three-stage training strategy for trainingconvergence. Extensive experiments demonstrate that \textit{Aparecium} is notonly robust against different digital distortions, but also can resist variousphysical distortions, such as screen-shooting and printing-shooting, even insevere cases including different shapes, curvature, folding, incompleteness,long distances, and big angles while maintaining high visual quality.Furthermore, some ablation studies are also conducted to verify our design.
