Super-Resolution Appearance Transfer for 4D Human Performances [article]

Marco Pesavento, Marco Volino, Adrian Hilton
2021 arXiv   pre-print
A pipeline is proposed for super-resolution appearance transfer from high-resolution static capture to dynamic video performance capture to produce super-resolution dynamic textures.  ...  A common problem in the 4D reconstruction of people from multi-view video is the quality of the captured dynamic texture appearance which depends on both the camera resolution and capture volume.  ...  The resolution of shape detail reconstruction is dependent on the image resolution and the 3D reconstruction systems use high-resolution (HR) cameras that can acquire higher resolution images of the subject  ...
