Abstract
Face tracking methods are increasingly critical for many expression mapping analysis applications, along its research track, deep convolutional neural network (DCNN-based) search techniques have attracted broad interests due to their high efficiency in 3D feature points. In this paper, we focus on the problem of 3D feature point’s extraction and expression mapping using a light-weight deep convolutional neural network (LW-DCNN) search and data conversion model, respectively. Specifically, we proposed novel light-weight deep convolutional neural network for 3D feature point’s extraction to solve the great initial shape errors in regression cascaded framework and the slow processing speed in traditional CNN. Furthermore, an effective data conversion model is proposed to generate the deformation coefficient to realize the expression mapping. Extensive experiments on several benchmark image databases validate the superiority of the proposed approaches.
