An electronic device and method for 3D face modeling based on neural networks is provided. The electronic device receives a two-dimensional (2D) color image of a human face with a first face expression and obtains a first three-dimensional (3D) mesh of the human face with the first face expression based on the received 2D color image. The electronic device generates first texture information and a first set of displacement maps. The electronic device feeds the generated first texture information and the first set of displacement maps as an input to the neural network and receives an output of the neural network for the fed input. Thereafter, the electronic device generates a second 3D mesh of the human face with a second face expression which is different from the first face expression based on the received output.
