No variations: Traditional (consistent) watermarking model.
Translation: Random watermark position per image.
Opacity X/255: Random opacity changes introduced per image, within X intensity levels around the global blend factor (see paper for details). Reconstruction is shown with (top) and without (bottom) estimating a blend factor per image.
Spatial perturbation Ypx: Random spatial deformation introduced per image, of at most Y pixels in each direction (see paper for details). Reconstruction is shown with (top) and without (bottom) flow estimation per image.
Trans. + Opac. X/255 + Pert. Ypx: A combination of random translation, opacity change and spatial deformation introduced per image.
