Abstract
Methods, mediums, and systems for constructing a 3D face model, including Deep Iterative Face Fitting (DIFF) and Recurrent Feature Alignment (ReFA). A processor provides a reference—containing a 3D mesh representing a median face, vertex positions, or surface points—as a template and UV texture mapping pointing the 3D mesh to a 2D UV space; receives input image(s) of a face and extracts geometry/texture features in an image space; extracts features in a UV space; iteratively produces a feature map via visual semantic correlation between UV and image spaces and regress geometry updates, predicting texture maps and comparing features, and inputs the map to an RNN-based neural optimizer of Gated Recurrent Units (GRU) to determine a hidden state. A head pose and/or updated 3D mesh/UV-space position map is output, each pixel in the UV-space map storing a coordinate of a corresponding point in a canonical space of the 3D mesh.
