Joint Multi-view Face Alignment in the Wild
The de facto algorithm for facial landmark estimation involves running a face detector with a subsequent deformable model fitting on the bounding box. This encompasses two basic problems: i) the detection and deformable fitting steps are performed independently, while the detector might not provide best-suited initialisation for the fitting step, ii) the face appearance varies hugely across dif...
متن کاملFace alignment in-the-wild: A Survey
Over the last two decades, face alignment or localizing fiducial facial points has received increasing attention owing to its comprehensive applications in automatic face analysis. However, such a task has proven extremely challenging in unconstrained environments due to many confounding factors, such as pose, occlusions, expression and illumination. While numerous techniques have been develope...
متن کاملJoint Face Alignment and 3D Face Reconstruction
We present an approach to simultaneously solve the two problems of face alignment and 3D face reconstruction from an input 2D face image of arbitrary poses and expressions. The proposed method iteratively and alternately applies two sets of cascaded regressors, one for updating 2D landmarks and the other for updating reconstructed poseexpression-normalized (PEN) 3D face shape. The 3D face shape...
متن کاملThe First 3D Face Alignment in the Wild (3DFAW) Challenge
2D alignment of face images works well provided images are frontal or nearly so and pitch and yaw remain modest. In spontaneous facial behavior, these constraints often are violated by moderate to large head rotation. 3D alignment from 2D video has been proposed as a solution. A number of approaches have been explored, but comparisons among them have been hampered by the lack of common test dat...
متن کاملMulti-View Face Alignment Using 3D Shape Model for View Estimation
For multi-view face alignment (MVFA), the non-linear variation of shape and texture, and the self-occlusion of facial feature points caused by view change are the two major difficulties. The state-of-the-art MVFA methods are essentially view-based approaches in which views are divided into several categories such as frontal, half profile, full profile etc. and each of them has its own model in ...
