  Image relighting aims to recalibrate the illumination setting in an image. In
this paper, we propose a deep learning-based method called multi-modal
bifurcated network (MBNet) for depth guided image relighting. That is, given an
image and the corresponding depth maps, a new image with the given illuminant
angle and color temperature is generated by our network. This model extracts
the image and the depth features by the bifurcated network in the encoder. To
use the two features effectively, we adopt the dynamic dilated pyramid modules
in the decoder. Moreover, to increase the variety of training data, we propose
a novel data process pipeline to increase the number of the training data.
Experiments conducted on the VIDIT dataset show that the proposed solution
obtains the \textbf{1}$^{st}$ place in terms of SSIM and PMS in the NTIRE 2021
Depth Guide One-to-one Relighting Challenge.
