  Image relighting is to change the illumination of an image to a target
illumination effect without known the original scene geometry, material
information and illumination condition. We propose a novel outdoor scene
relighting method, which needs only a single reference image and is based on
material constrained layer decomposition. Firstly, the material map is
extracted from the input image. Then, the reference image is warped to the
input image through patch match based image warping. Lastly, the input image is
relit using material constrained layer decomposition. The experimental results
reveal that our method can produce similar illumination effect as that of the
reference image on the input image using only a single reference image.
