Claim 0:
1. A computer-implemented method for retrieval of multispectral bidirectional reflectance distribution function (BRDF) parameters by using red-green-blue-depth (RGB-D) data, the computer-implemented method comprising:
capturing at least one image of one or more objects in a scene, wherein the captured at least one image of the one or more objects comprises RGB-D data including color and geometry information of the one or more objects;
reconstructing the captured at least one image of the one or more objects to one or more three-dimensional (3D) reconstructions by using the RGB-D data;
classifying, by a deep neural network, the BRDF of a surface of the one or more objects based on the one or more 3D reconstructions, wherein the deep neural network comprises an input layer, an output layer, and at least one hidden layer between the input layer and the output layer; and
retrieving the multi spectral BRDF parameters by approximating the classified BRDF using an iterative optimization method.
