In this paper, we present a novel method for face reconstruction from multi-posed face images taken under arbitrary unknown illumination conditions. Previous work shows that any face image can be represented by a set of low dimensional parameters: shape parameters, spherical harmonic basis (SHB) parameters, pose parameters and illumination coefficients. Thus, face reconstruction can be performe...

This paper investigates the evaluation of dense 3D face reconstruction from a single 2D image in the wild. To this end, we organise a competition that provides a new benchmark dataset that contains 2000 2D facial images of 135 subjects as well as their 3D ground truth face scans. In contrast to previous competitions or challenges, the aim of this new benchmark dataset is to evaluate the accurac...

The variation of facial appearance due to the viewpoint or pose obviously degrades the accuracy of any face recognition systems. One solution is generating the virtual frontal view from any given non-frontal view to obtain a virtual gallery/probe face. As the state-of-the-art face recognition algorithm, linear regression computes a reconstruction matrix from the images of each subject and then ...

We present a differentiable ray-tracing based novel face reconstruction approach where scene attributes – 3D geometry, reflectance (diffuse, specular and roughness), pose, camera parameters, illumination are estimated from unconstrained monocular images. The proposed method models via novel, parameterized virtual light stage, which in-conjunction with ray-tracing, introduces coarse-to-fine opti...

The use of 3D data in face image processing applications has received considerable attention during the last few years. A major issue for the implementation of 3D face processing systems is the accurate and real time acquisition of 3D faces using low cost equipment. In this paper we provide a survey of 3D reconstruction methods used for generating the 3D appearance of a face using either a sing...

Accurate and plausible 3D face reconstruction remains a difficult problem up to this day, despite the tremendous advances in computer technology and the continuous growth of the applications utilizing 3D face models (e.g. biometrics, movies, gaming). In this paper, a two-step technique for efficient 3D face reconstruction from a set of face images acquired using an uncalibrated camera is presen...
