The work introduces PixelDense, which routes DINOv2 and SAM2 through a semantic projection stream and Depth Anything v2 and Metric3D v2 through a geometric projection stream, adding a weight-space orthogonality penalty that keeps the two streams in disjoint subspaces; with a single recipe on PixelGen and DeCo it improves GenEval, DPG-Bench and HPS v2.1, raising PixelGen-XXL's GenEval Overall from 0.7927 to 0.8093 and beating every single-teacher and unfactored multi-teacher variant.
