The watermarks are shaded in red color. watermarks are shaded in red colour.Conventionally, watermarks are inserted in imperceptible positions to enhance security. Within this experiment, we purposely embed the watermarks into big curvy spaces within the test models to evaluate the capability of our encoding procedure. As the resultant photos show, the watermarks blend nicely with their host models. The watermarks originate from a flat 2D pattern along with the ROIs are comprised with voxels, scattering in curvy distance levels. You’ll find massive geometric and topological imparities amongst these two kinds of media. The experimental final results show that the SOM subroutine bridges the gaps and successfully inserts the watermark into these voxel models. Apart from watermarking the test models, blank-and-white photos of the watermarks are created and recorded for authentication goal. These watermark images are displayed inside the upper row of Figure 7. The watermarks of the tetrapod and mug are rendered within the front view although the watermark of the bowl is imaged through the left upper corner on the AABB. After being watermarked, the digital models were converted into G-code programs by utilizing the slicer. The resultant G-code applications would create fingerprinted contents if they have been interpreted by simulators or executed by 3D printers.Figure 7. the recorded and extracted watermarks in the tetrapod (left), the bowl (middle), as well as the mug (appropriate).
