Salient‑points‑guided face alignment

Regression-based face alignment approach is fast and accurate but is always limited by the initial face. Aim at limitation of initialization in regression methods, this paper presents a novel two-stage framework named salient-points-guided face alignment. In rst stage, we use cascade regression framework to train a salient points (eye centers, nose, mouth corners) localization model. Then the salient points information is used as a guidance for search- ing the similar faces from training set. I
