Abstract
Methods and systems for predicting light probes for outdoor images are disclosed. A light probe database is created to learn a mapping from the outdoor image's features to predicted outdoor light probe illumination parameters. The database includes a plurality of images, image features for each of the plurality of images, and a captured light probe for each of the plurality of images. A light probe illumination model based on a sun model and sky model is fitted to the captured light probes. The light probe for the outdoor image may be predicted based on the database dataset and fitted light probe models.
Claims37
A computer-implemented method, comprising predicting a light probe for an outdoor image based on a learned mapping from the outdoor image's features to light probe illumination parameters.
A system, comprising:
- a camera configured to take an outdoor image;
- and
- a computer configured to predict a light probe for the outdoor image based on a learned mapping from the outdoor image's features to light probe illumination parameters.
A method of creating a light probe database, comprising:
- capturing a plurality of images for each of a plurality of locations with a camera;
- capturing the light probes for each of the plurality of images;
- and
- recovering image features for each of the plurality of captured images.
