Researchers have developed GroundControl, a novel diffusion model for synthesizing novel views of outdoor scenes by conditioning on both street-level images and satellite imagery. This approach aims to improve spatial layout realism and scene extrapolation compared to models that rely solely on street-level views. The method does not require 3D reconstruction and has shown superior performance on outdoor datasets, particularly when target views have minimal overlap with the input images. Separately, a study compared sequential and fully conditional specifications for tree-based synthesis of health data, finding no general superiority of one method over the other, with sequential synthesis being sensitive to variable ordering and fully conditional specification incurring higher computational costs.
