      Adaptive face modelling for reconstructing 3D face shapes from single 2D images

      Maghari, Ashraf Y. A.; Venkat, Ibrahim; Liao, Iman YI; Belaton, Bahari (IET Digital Library, 2014)
      Example-based statistical face models using principle component analysis (PCA) have been widely deployed for three-dimensional (3D) face reconstruction and face recognition. The two common factors that are generally concerned ...
    • Distance-Based 3D Face Reconstruction Using Regularization

      Maghari, Ashraf Y. A.; Liao, Iman YI; Venkat, Ibrahim; Belaton, Bahari (Springer, Cham, 2015)
      This study addresses the problem of reconstructing 3D face shapes from a small set of 2D facial points. By using Maximum Posterior Probability estimation, prior information modeled by PCA is connected to Tikhonov regularization ...
    • Effect of Training Sample on Reconstructing 3D Face Shapes from Feature Points

      Maghari, Ashraf Y. A.; Venkat, Ibrahim; Liao, Iman YI; Belaton, Bahari (Springer, Cham, 2013)
      Statistical learning models are recognized as important emerging methodologies in the area of data reconstruction. The learning models are trained from a set of examples to reach a state where the model will be able to ...

      PCA-based Reconstruction of 3D Face shapes using Tikhonov Regularization.

      Maghari, Ashraf Y. A.; Venkat, Ibrahim; Liao, Iman YI; Belaton, Bahari (2013)
      Reconstructing a 3D face shape from a limited number of 2D facial feature points is considered as an ill-posed problem which can be solved using regularization. Tikhonov regularization is a popular method that incorporates ...

      Reconstructing 3D face shapes from single 2D images using an adaptive deformation model

      Maghari, Ashraf Y. A.; Venkat, Ibrahim; Liao, Iman YI; Belaton, Bahari (Springer, Cham, 2013)
      The Representational Power (RP) of an example-based model is its capability to depict a new 3D face for a given 2D face image. In this contribution, a novel approach is proposed to increase the RP of the 3D reconstruction ...

      Reconstruction of 3D faces by shape estimation and texture interpolation

      Maghari, Ashraf Y. A.; Venkat, Ibrahim; Belaton, Bahari (2013)
      This paper aims to address the ill-posed problem of reconstructing 3D faces from single 2D face images. An extended Tikhonov regularization method is connected with the standard 3D morphable model in order to reconstruct ...
