description | Large head pose variations and severe occlusion are challenging problems for face alignment. In this paper,
we propose a Structure-aware Heatmap and Boundary map Regression Network (SHBRN), consisting of a rough
estimation network and a refinement network, to accounting for the structural geometry of faces via
the boundary map. Specifically, in the rough estimation network, a structure-aware module is designed
to capture low-level features rich in structure information, and both heatmaps and boundary maps are
predicted by the hourglass network. In this way, the network can not only estimate the initial location
of keypoints, but also implicitly take the geometric structure into consideration. In the refinement
network, the boundary maps and heatmaps are fused with the features extracted in the rough stage via
attention mechanism. As a result, the network can combine the global information with local appearance
for obtaining complete face representations, and also optimize the spatial relationship of different
keypoints. Our proposed network is superior to the existing methods on 300W, COFW, and AFLW datasets,
especially for those challenging situations, which proves the effectiveness and robustness of our model. |
