Deep Sky Modeling for Single Image Outdoor Lighting Estimation


Recent work on outdoor illumination estimation made use of existing analytical sky models. However, these sky models can only represent a small subset of the vast diversity of the outdoor lighting appearance. In this presentation, we will discuss our novel data-driven and learned sky model and describe a method to perform illumination estimation from a single image, solving both problems of lighting modelling and estimation end-to-end. Finally, we will demonstrate the versatility and expressivity of our learned sky model and show that it can be used to recover plausible illumination from a single limited field of view image, leading to visually pleasant virtual object insertions.
