Local 3D Shape Analysis for Facial Expression Recognition
Found in: Pattern Recognition, International Conference on
By Ahmed Maalej, Boulbaba Ben Amor, Mohamed Daoudi, Anuj Srivastava, Stefano Berretti
Issue Date:August 2010
pp. 4129-4132
We investigate the problem of facial expression recognition using 3D face data. Our approach is based on local shape analysis of several relevant regions of a given face scan. These regions or patches from facial surfaces are extracted and represented by s...
 
A Set of Selected SIFT Features for 3D Facial Expression Recognition
Found in: Pattern Recognition, International Conference on
By Stefano Berretti, Alberto Del Bimbo, Pietro Pala, Boulbaba Ben Amor, Mohamed Daoudi
Issue Date:August 2010
pp. 4125-4128
In this paper, the problem of person-independent facial expression recognition is addressed on 3D shapes. To this end, an original approach is proposed that computes SIFT descriptors on a set of facial landmarks of depth images, and then selects the subset...
 
Enhancing 3D Face Recognition By Mimics Segmentation
Found in: Intelligent Systems Design and Applications, International Conference on
By Boulbaba Ben Amor, Mohsen Ardabilian, Liming Chen
Issue Date:October 2006
pp. 150-155
In this paper, we present a novel approach for face recognition and authentication based on dimensional surface matching. While most of existing methods use facial intensity images, a recent set of approaches focus on introducing depth information to surmo...
 
New Experiments on ICP-Based 3D Face Recognition and Authentication
Found in: Pattern Recognition, International Conference on
By Boulbaba Ben Amor, Mohsen Ardabilian, Liming Chen
Issue Date:August 2006
pp. 1195-1199
<p>In this paper, we discuss new experiments on face recognition and authentication based on dimensional surface matching. While most of existing methods use facial intensity images, a newest ones focus on introducing depth information to surmount so...
 
An Improved 3D Human Face Reconstruction Approach Based on Cubic Splines Models
Found in: 3D Data Processing Visualization and Transmission, International Symposium on
By Boulbaba Ben Amor, Mohsen Ardabilian, Liming Chen
Issue Date:June 2006
pp. 279-286
In this paper, we develop a new hybrid active vision/ geometric modeling approach dedicated to 3D human face recovery. Initially, a 3D coarse reconstruction is obtained via a structured-light assisted stereo sensor. Here, the stereo matching problem is res...
 
3D Face Recognition under Expressions, Occlusions, and Pose Variations
Found in: IEEE Transactions on Pattern Analysis and Machine Intelligence
By Hassen Drira,Boulbaba Ben Amor,A. Srivastava,M. Daoudi,R. Slama
Issue Date:September 2013
pp. 2270-2283
We propose a novel geometric framework for analyzing 3D faces, with the specific goals of comparing, matching, and averaging their shapes. Here we represent facial surfaces by radial curves emanating from the nose tips and use elastic shape analysis of the...
 
Gender and 3D facial symmetry: What's the relationship?
Found in: 2013 10th IEEE International Conference on Automatic Face & Gesture Recognition (FG 2013)
By Baiqiang Xia,Boulbaba Ben Amor,Hassen Drira,Mohamed Daoudi,Lahoucine Ballihi
Issue Date:April 2013
pp. 1-6
Although it is valuable information that human faces are approximately symmetric, in the literature of facial attributes recognition, little consideration has been given to the relationship between gender, age, ethnicity, etc. and facial asymmetry. In this...
   
Fully automatic 3D facial expression recognition using a region-based approach
Found in: Proceedings of the 2011 joint ACM workshop on Human gesture and behavior understanding (J-HGBU '11)
By Boulbaba Ben Amor, Liming Chen, Mohamed Daoudi, Mohsen Ardabilian, Pierre Lemaire
Issue Date:December 2011
pp. 53-58
In this paper, we address the problem of automatic 3D facial expression recognition. Automatic 3D Facial Expression Recognition techniques are generally limited in that they require manual, precise landmark points. Here, we propose a framework capable of h...
     
Elastic radial curves to model 3D facial deformations
Found in: Proceedings of the ACM workshop on 3D object retrieval (3DOR '10)
By Anuj Srivastava, Boulbaba Ben Amor, Hassen Drira, Mohamed Daoudi
Issue Date:October 2010
pp. 75-80
In this paper we study the challenging problem of 3D face recognition in presence of facial expressions. Therefore, the facial surfaces are represented by an indexed collections of radial curves on them, emanating from the nose tips. Facial shapes comparis...
