A novel relighting is then produced by modifying the illumination parameters. Our solution capture shadow using a dedicated shadow prediction map, and does not rely on accurate geometry estimation. ...
We evaluate our technique subjectively and objectively using a new dataset with ground-truth relighting. ...
