Face Alignment Across Expression Based on Multi State Layered Model
摘要
Abstract
The range of expression variety is discretized to be multi-state component model, which is used to describe nonlinear variety of a face. The hierarchical face alignment is achieved based on the cascade convolutional neural networks by introducing multi direction local gradient information and constructing the corresponding backprojection probability map to improve appearance representation of traditional grey images. The face shape initialization is realized and the current component state is predicted, according to the whole face and different regions. The face shape parameters are regressed to achieve final fine alignment, according to the chosen face model under correct state. The experiments performed on database demonstrate that the proposed method improves the robustness of face alignment under exaggerated expressions and correct rate, and convergence rate are increased under the considerable computational complexity.关键词
