Abstract:

The tabulated BRDFs (bidirectional reflectance distribution function) can realistically reproduce the surface appearance of objects. However, due to their high-dimensional characteristics and the fact that a single planar image contains limited reflectance information and small differences, methods for estimating tabulated BRDFs typically require complex equipment or the capture of multiple images. To address this issue, a method is proposed for reconstructing material properties from a single image by combining neural networks with singular value decomposition. The singular value decomposition is introduced to compress the material into a lower-dimensional space. The task of solving the tabulated BRDFs is simplified to estimating the weight vectors of material bases. By combining a deep convolutional neural network, a mapping relationship between the single planar image and the weight vector is established. A logarithmic relative loss function is designed to suppress high dynamic range within the material. A planar sample dataset is constructed to train the network model. A two-sided training method is proposed to avoid ringing at the highlights. Experiments results on both synthetic and real data show that the proposed method outperforms previous methods.
