A unified framework for robust 3D watermarking based on feature integration [PDF]

open access: yesScientific Reports
In this paper, we present a unified framework for robust 3D embedded watermarking and non-embedded watermarking based on feature integration. It begins by segmenting a 3D model into multiple separate sub-models via empirical mode decomposition (EMD). And

Region-based image watermarking [PDF]

open access: yesIEEE Transactions on Image Processing, 2001
We introduce a novel method for embedding and detecting a chaotic watermark in the digital spatial image domain, based on segmenting the image and locating regions that are robust to several image manipulations. The robustness of the method is confirmed by experimental results that display the immunity of the embedded watermark to several kinds of ...
