Abstract
Methods and systems for estimating HDR sky light probes for outdoor images are disclosed. A precaptured sky light probe database is leveraged. The database includes a plurality of HDR sky light probes captured under a plurality of different illumination conditions. A HDR sky light probe is estimated from an outdoor image by fitting a three dimensional model to an object of interest in the image and solving an inverse optimization lighting problem for the 3D model where the space of possible HDR sky light probes is constrained by the HDR sky light probes of the database.
