Fig. 1. Spectral Decomposition on Shapes – Any function f(x) on surface 1 (top row), or g(x) on surface 2 (bottom row) can be written as a sum of weighted…
compared to the state of the art. In addition, we show qualitative improvements on real X-ray data. 1 Introduction Minimally-invasive interventions are often guided by fluoroscopic X-ray imaging. X-ray imaging…
