WebOct 8, 2015 · A model is trained to predict relative reflectance ordering between image patches from large-scale human annotations, producing a data-driven reflectance prior and it is shown how to naturally integrate this learned prior into existing energy minimization frame-works for intrinsic image decomposition. We propose a data-driven approach for … WebJul 26, 2024 · Photo-realistic editing of outdoor scenes from photographs requires a profound understanding of the image formation process and an accurate estimation of the scene geometry, albedo and illumination. A delicate manipulation of the lighting can then be performed while keeping the scene albedo and geometry unaltered. We present the first …
