Due to magnetic field inhomogeneities, EPI images are geometrically distorted, predominantly along the phase-encoding direction. Currently, the distortion is either ignored or com...

We propose to embed watermarks by modifying the texture mapping information of 3D models rather than modifying the geometry information or texture image as existing works do. We p...
