Editor's Note: This is Part 6 of 14 of a study introducing a method for improving how light and shadows can be applied to human portraits in digital images. Read the rest below.
We supervise both intrinsic image attributes and relit images using their corresponding ground truths, obtained from the lightstage. We employ a combination of reconstruction, perceptual [24], adversarial [22], and specular [34] losses.
Final Loss. The SwitchLight is trained in an end-to-end manner using the weighted sum of the above losses:
We empirically determined the weighting coefficients.
