Claim 8:
9. A system for retrieval of multi lispectral bidirectional reflectance distribution function (BRDF) parameters by using red-green-blue-depth (RGB-D) data, the system comprising:
an RGB-D camera configured to capture 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; and
a computer comprising:
memory configured to store a deep neural network comprising an input layer, an output layer, and at least one hidden layer between the input layer and the output layer; and
at least one processor configured to store program instructions that, when executed on the at least one processor, cause the system to:
reconstruct 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;
classify the BRDF of a surface of the one or more objects based on the one or more 3D reconstructions, using the deep neural network; and
retrieve the multi lispectral BRDF parameters by approximation of the classified BRDF using an iterative optimization.
