Abstract: Highlights•A new feature-extraction approach for efficient FR based on directional features.•An augmented multi-stage or multi-regularization convex optimization.•Results on various face databases demonstrate the effectiveness of our approach.•The approach presents a trade-off between recognition and computational complexity.•Three protocol experimental are tested among them the SSPP.
