Dense Face Alignment

Understand

Face alignment is a classic problem in the computer vision field.

• Previous works mostly focus on sparse alignment with a limited number of facial landmark points, i.e., facial landmark detection.
• In this paper, for the first time, we aim at providing a very dense 3D alignment for large-pose face images.
• To achieve this, we train a CNN to estimate the 3D face shape, which not only aligns limited facial landmarks but also fits face contours and SIFT feature points.
